What is a rotary screw air compressor?

A Rotary Screw Air Compressor is a compressor that uses a rotary-type positive displacement mechanism, called a rotary screw, air-end. Rotary Screw Compressors are commonly used to replace piston compressors, in commercial and industrial applications, where large volumes of high pressure air are needed. Another name used (though not frequently) is “twin screw compressor”.

The compression process of a Rotary Screw is a quite different than that of a reciprocating piston compressor, as the Rotary Screw air-end generates compression in a continuous sweeping motion. There is very little pulsation or surging of flow, which occurs with piston compressors. Rotary Screw Compressors also use two inter-twined helical shaped screws, known as rotors, to compress the air. These rotors are precision machined to extremely tight tolerances, whereby the vanes on the rotors are almost touching, and typically just a few thousandths of an inch apart.

In an oil-flooded Rotary Screw Compressor, lubricating oil bridges the space between the rotor vanes, both providing a hydraulic seal and transferring mechanical energy between the driving and driven rotor. Air enters the system at the “suction side” of the air-end and moves through the rotor vanes as the screw rotors rotate. The inter-twined rotors force the air and oil through the air-end, which eventually exits at the end of the screws. The air and oil then go through a separation process. The air is cooled and routed to air lines and a receiver. The oil is also cooled, filtered and re-routed back into the air-end in a closed loop system

A rotary-screw compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism. They are commonly used to replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications or to operate high-power air tools such as jackhammers and impact wrenches. For smaller rotor sizes the inherent leakage in the rotors becomes much more significant, leading to this type of mechanism being unsuitable for small air compressors.

The gas compression process of a rotary screw is a continuous sweeping motion, so there is very little pulsation or surging of flow, as occurs with piston compressors. This also allows screw compressors to be significantly quieter and produce much less vibration than piston compressors, even at large sizes, and produces some benefits in efficiency.

What’s the difference between a fan and a blower?

HVAC systems rely on ventilation equipment for space heating and air conditioning, since chillers and boilers by themselves cannot deliver the heating or cooling effect where it is required. In addition, ventilation systems ensure a constant supply of fresh air for indoor spaces. Based on the pressure and airflow requirements of each application, either a fan or a blower is used.

Before discussing the main types of fans and blowers, it is important to understand the difference between both concepts. The American Society of Mechanical Engineers (ASME) defines fans and blowers based on the ratio between discharge pressure and suction pressure.

Fan: Pressure ratio up to 1.11
Blower: Pressure ratio from 1.11 to 1.2
Compressor: Pressure ratio exceeds 1.2

Fans and blowers are necessary for air to overcome the flow resistance caused by components like ducts and dampers. There are many types available, each suited for certain applications. Choosing the right type helps optimize HVAC performance, while poor selection leads to energy waste.
Types of Blowers

As previously stated, blowers operate with a pressure ratio of 1.11 to 1.2, which makes them intermediate between a fan and a compressor. They can produce much higher pressures than fans, and they are also effective in industrial vacuum applications that require negative pressurization. Blowers are divided into two main categories: centrifugal and positive displacement.

What’s the difference between a fan and a blower?

Centrifugal blowers have some physical similarity with centrifugal pumps. They normally include a gear system to achieve speeds well over 10,000 rpm. Centrifugal blowers can have a single-stage or a multi-stage construction, where the single-stage design offers a higher efficiency, but the multi-stage design provides a wider airflow range at steady pressure.

Like fans, centrifugal blowers have applications in HVAC. However, thanks to their superior pressure output, they are also used in cleaning equipment and automotive applications. Their main limitation is that airflow decreases rapidly when an obstacle raises pressure, making them unsuitable for applications with a high chance of clogging.

Positive-displacement blowers have a rotor geometry designed to capture pockets of air, driving flow in the intended direction at high pressure. Although they rotate at lower speeds than centrifugal blowers, they can produce enough pressure to blow away objects clogging the system. Another important difference with centrifugal options is that positive-displacement blowers are typically driven by belts instead of gears.

Fans and blowers are normally specified based on the pressure and airflow requirements of each application, as well as site-specific conditions such as dust and temperature. Once the right type of fan or blower has been specified, performance can normally be enhanced with control systems. For example, variable frequency drives (VFD) can drastically reduce the electricity consumption of fans that operate intermittently.

How does a rotary lobe blower work?

Rotary lobe pumps have been in industrial use since the late 1800’s. They were invented by the Roots Brothers around 1860. The brothers were looking for a way to build a more efficient “water motor” for a mill. When they were working on it, one of the brothers rotated the shaft, and it blew the other brother’s hat off. A superintendent of an iron foundry saw this, and said that would be helpful in smelting iron.

From there the Roots Blower Company was started and it sold “Roots Blowers” to iron foundries and for mine ventilation. The applications that rotary lobe blowers has since expanded to many different applications, and hundreds of different companies make them. They’re often still called “Roots Blowers,” and that company still exists today as a part of General Electric.

Rotary lobe pumps are used in a wide variety of applications, and not just in compressed air. The first engine supercharger was a rotary lobe pump. Interestingly enough, one of their most common uses is in mills, though not as the original Roots Brothers had intended. Rotary lobe blowers are nearly in every industrial grain, rice or flour mill, but they’re used for pneumatic conveying.

Rotary lobe pumps are positive displacement pumps. However, unlike the technologies we’ve covered before, no compression happens inside of the pump. There is reduction of volume to create pressure, but it’s not inside the pump.

So how do they compress air?

Inside the pump housing you’ll have two rotors that each have either two or three lobes. If the rotors have two lobes, they are shaped like the number 8.

If the rotors have three lobes they look like this:

Rotary lobe pumps with more than three lobes do exist, but as far as I know they are not used in compressed air.

One of the rotors is driven by the motor or engine and the other is geared to the driven one. When one spins, the other spins in the opposite direction with very precise timing and clearances.

Air is sucked into the inlet, and it is forced around by the lobes, and then pushed out of the discharge. A very small amount can escape back through the clearance in the rotors, and this is called the “slip.” The slip is why blowers are only used for very low pressures.

When the air is discharged out of the pump, this is when the volume reduction occurs occurs. The air gets forced down the pipe. Unlike the other positive displacement pumps we’ve covered, that take a fixed amount of air and gradually reduce its volume to increase pressure, the rotary lobe pumps takes a fixed volume and continually forces more air into it to increase pressure.

The amount of pressure a rotary lobe pump can produce is very small compared to what a piston or screw pumps can do. They’re referred to as blowers, because they produce low pressure at a high volume. They’re also used for high volume, light vacuum applications.

How does a rotary lobe blower work?

Pros and Cons:

1. Can produce a very high volume of air.

2. Very little maintenance – the compression chamber is oil-free, so you only have gearbox oil and maybe an air filter or silencer to change.

3. Plug and play – most manufacturers make the pumps to fit in the same spot as the other brands. Additionally these standard designs have been around for decades. So you might have a blower system from the 50’s, and most likely you can buy a new pump and it will drop right in the system with no modifications and perform the same.

4. Durable. The pumps can take a pretty good beating. They’re often used in harsh environments. Just make sure if it’s extremely hot, to change the gearbox oil more often.


1. Limited pressure range. They can only give you about 15 psi.

2. They’re not always the most energy efficient, due to the slip. Sometimes other technologies can out perform it.

3. Loud. Usually it’s not big deal, because these are in industrial environments where the noise doesn’t matter. However, you can put a silencing box around them or add silencers to reduce the noise.

If you have an application that needs below 15 psi of air, a large volume of air, and you have a dirty or dusty environment, a rotary lobe pump is often a good choice. As always, when sizing any application, contact your local compressed air expert.

What is a rotary blower?

Rotary piston compressors, also known as rotary blowers, roots compressors or roots blowers, are robust endurance runners. They convey and compress air or gases in a continuous air or gas flow. Positive displacement blowers are assigned to the group of valveless positive displacement compressors without internal compression.

Rotary piston blowers are used to generate both positive pressure and negative pressure or vacuum. Rico Positive Displacement Blowers have high availability, energy efficiency and freedom from oil in robust industrial applications and are durable, economical and powerful.

Two identical, normally symmetrical, counter-rotating rotors operate in one housing and are synchronized with a series of gears.

What is the difference between fan blower and compressor?

Turbomachinery equipment is generally segmented based on whether it extracts energy (e.g., turbines) or adds energy (e.g., pumps and compressors). The addition of energy is usually used to compress or move a fluid. When the fluid is a gas, the turbomachinery equipment is typically referred to as a fan, blower or compressor. This blog will explore the differences between these three devices and where they are used.

It is important to note that nomenclature in turbomachinery is not standardized and can vary from country to country and industry to industry. In fact, some definitions in the turbomachinery industry can seem downright arbitrary! As a general rule, the industry does recognize certain differences between fans, blowers, and compressors. While all three devices generate a pressure rise in a gas and have a corresponding flow capability, they are differentiated by the amount of pressure rise created by each device, and consequently the resulting application. Let’s explore each in turn.


Fans are generally considered to have pressure ratios up to 1.11. Pressure ratio here is defined as the ratio of the fan discharge pressure to the fan inlet pressure, which is sometimes called the suction pressure. Pressure ratios of 1.11 and lower are very low in the turbomachinery world. Consider a fan you might have in your living room that helps keep you cool in the summer. The purpose of this fan is to create forced convection cooling of your skin by moving air across your body at a reasonable velocity. The pressure rise required to do this is small. The fan must only overcome local losses of the fan itself, including losses in the fan blading, resistance losses from other parts of the fan, such as the fan cage, and downstream mixing losses. The pressure just upstream and just downstream of the fan is ambient, so the pressure rise generated by the fan quickly overcomes these local losses. Pressure ratios for fans can be so small (perhaps 1.01) that fan pressure rise is typically given in head rather than pressure ratio, for instance, 2 inches of water. Generally, fans are devices that move larger amounts of a gas with a very low increase in pressure.

What is the difference between fan blower and compressor?


The term blower is sometimes used interchangeably with fan. In general, a blower has a slightly higher pressure rise than a fan: from 1.11 to 1.2. Here again, pressure rise is defined as discharge pressure over inlet pressure. Blowers are used in situations where the system resistance is higher than that for a fan. It helps to picture a blower as a device that needs to move a gas through a resistance, such as ducting, which obviously has a much higher system resistance than just the cage on a fan. A simple example is a forced hot air furnace which needs to move air throughout a house. Another example is a hair dryer, or blow dryer, which must overcome somewhat higher system losses than a basic fan (specifically the heating element and the nozzle that is used to accelerate the flow to a higher velocity). Generally, a blower is viewed as a device moving a generous amount of air across a moderate system resistance.

What is the difference between fan blower and compressor?


For applications where the required pressure rise is greater than 1.2, the device is usually referred to as a compressor, because more ‘compression’ is done. In fact, the purpose of a compressor is more to increase the pressure of the gas, rather than move a large amount of gas. One example is the turbocharger you might have in your car. The turbocharger compressor might operate at a pressure ratio of 3.5, forcing (compressing) air into the engine. In this type of application, the system wants to operate at a higher pressure level for thermodynamic or system reasons. In other applications, system losses are much higher, so more pressure rise is needed to overcome them. The volumetric flow rates are typically viewed as relatively small compared to a cooling fan or furnace blower. There are many industrial applications where compressors have very large flow rates, so, like everything, there are exceptions to the rule. Pressure ratios much greater than 1.2 are not uncommon for compressors, especially centrifugal compressors. Pressure ratios above 10 have been achieved in a single stage. So, think of a compressor as a device that can generate much higher pressure rise, across a wide range of flow rates.

To summarize, think of fans, blowers, and compressors as being selected and differentiated by the application, specifically the system resistance, with the required pressure ratio increasing respectively for these three devices:

Fans: Pressure ratio up to 1.11
Blowers: Pressure ratio of 1.11 to 1.2
Compressors: Pressure ratio greater than 1.2

Because of the different performance requirements for these three devices, pressure rise relative to flow rate, fan, blower, and compressor impeller geometries usually differ from each other, a subject I will cover in a future blog.

You might wonder how a pump relates to fans, blowers, and compressors. Well, a pump is a device that works on a liquid instead of a gas, raising the pressure of the liquid. Pumps generally do not have the refined breakdown in pressure ratio (head rise) that fans, blowers, and compressors do for gas applications.

Functionality of the “Roots” Positive Displacement Blowers

The air flow depends on the position and direction of the rotors. The typical installation provides a constant air flow, and that the rotational direction is dependent on the “Roots” blower design. As a side note, the Roots blower design is enduring and durable. The rotary positive air blower was designed in the 1850s and patented in 1860 by brothers Francis and Philander Roots and the Roots name has remained as the description of the design.

The basic principle is as follows: the process starts with air flowing from the inlet port into the element chamber. The timed rotation of the rotors against the wall of the chamber creates so-called “air flow direction”. There is still atmospheric pressure in these chambers.

As soon as the first lobe passes the opening to the pressure side, the system pressure is adjusted. This is called isochoric compression. The rotors seal each other off to the inside, which prevents a change of pressure.

What is a lobe blower?

Compression Principle

The performance of the compression principle is as follows. Positive displacement blowers operate using the isochoric compression principle, also known as external compression. The pressure increase is achieved by intermittently transporting a gaseous medium (e.g. atmospheric air) into a system. By forcing the medium from atmospheric conditions into a system with a given resistance (e.g. a water column, distribution network), the relevant pressure increase is achieved. The blower will operate at a controlled output level to overcome this resistance.

Positive displacement blowers are made up of two or three conjugate lobe shaped rotors which rotate inside a pre-machined chamber. The chamber is sealed by the rotating rotors. The rotors are synchronised by means of a timing 1:1 gear ratio, positioned at the end of the shafts. Bearings are positioned externally to the compression chamber with an oil lubricated system. The drive shafts have labyrinth style oil seals, so called because of the labyrinth of grooves that the oil must pass through. The splash lubrication system uses a fine mist of oil for lubrication.

Our products include vacuum pumps, screw compressors, and lobe compressors, and we can deliver the rotary lobe compressor to meet and exceed your application requirements. Our systems have a reputation for being low maintenance.

What is the difference between a Roots blower and a screw blower?

A supercharger is one of the oldest methods of adding power to an engine, so it’s no surprise that racers around the world have always found ways to harness that power to make their cars faster. The supercharger has been a staple in drag racing since the sport began, from the first hot rods on the salt flats to the beginnings of Top Fuel racing. The two most common types of superchargers in drag racing are the roots and screw blowers that can be seen sticking out of the hoods of different racecars in venues around the world. Today, we’re going to take a look at these superchargers to discuss their internal workings and how they’re so similar yet so very different.

Because an engine acts as a giant air pump, the best way to make more power is to increase the amount of air that flows through it. The supercharger forces more oxygen into the motor, allowing more fuel to burn, and that in turn creates a higher power output. The roots and screw blowers you see at the track may look like they bring air into the motor the same, but there are actually a few differences in how they function.

Blowers have been a part of drag racing since its earliest days and old blowers can still be seen on nostalgia cars like these.

The Roots Blower

The roots supercharger acts like a large positive displacement air pump on the top of a motor and is what the nitro-guzzling NHRA Top Fuel and Funny Cars use to make their power. Inside the blower, there are two rotors that typically have three lobes each, and they’re what move the air inside the case. The air is held inside pockets that are around the lobes and is then moved from the intake to the discharge side of the lobe. As this is done, the rotors move more air than the motor can ingest, creating boost inside the manifold of the supercharger.
Roots Blower Vs The Screw Blower

When it comes down to it, the goal of a roots and screw blower is the same; move as much air into the motor as possible to increase power. How well that’s done between the two is where the big differences arise and show which blower can make more power.

Andy Severyn, John Sears, and Chelsea Clark are the core group of people who run PSI Superchargers, one of the biggest names in the roots and screw blower market. They have spent years perfecting both kinds of blowers and know what it takes to make big power with each.

What is the difference between a Roots blower and a screw blower?

Roots Blower Overdrive

A roots blower can have a certain amount of overdrive based on the class you are in. Janis explains how overdrive in a roots blower works. “While you would think that turning a supercharger at a higher overdrive would make more power, it’s not always the case. It actually will create a lot of heat in the supercharger, which then causes the intake temperature to rise, thus making your turn up much more difficult. In our particular case, the NHRA mandates that our supercharger has an overdrive limit of 16.5 percent overdrive. This means that with the pulley combination of the top pulley and the bottom pulley, the blower is turning 16.5 percent faster than the actual engine RPM. It goes hand in hand no matter what overdrive combination you are using.”

How does a Roots blower work?

There are three types of superchargers: Roots, twin-screw and centrifugal. The main difference is how they move air to the intake manifold of the engine. Roots and twin-screw superchargers use different types of meshing lobes, and a centrifugal supercharger uses an impeller, which draws air in. Although all of these designs provide a boost, they differ considerably in their efficiency. Each type of supercharger is available in different sizes, depending on whether you just want to give your car a boost or compete in a race.

How does a Roots blower work?

The Roots supercharger is the oldest design. Philander and Francis Roots patented the design in 1860 as a machine that would help ventilate mine shafts. In 1900, Gottleib Daimler included a Roots supercharger in a car engine.

As the meshing lobes spin, air trapped in the pockets between the lobes is carried between the fill side and the discharge side. Large quantities of air move into the intake manifold and “stack up” to create positive pressure. For this reason, Roots superchargers are really nothing more than air blowers, and the term “blower” is still often used to describe all superchargers.

Roots superchargers are usually large and sit on top of the engine. They are popular in muscle cars and hot rods because they stick out of the hood of the car. However, they are the least efficient supercharger for two reasons: They add more weight to the vehicle and they move air in discrete bursts instead of in a smooth and continuous flow.

Should I get a leaf blower or vacuum?

Should I get a leaf blower or vacuum?

Should I get a leaf blower or vacuum?

Leaf blowers and leaf vacuums both are powerful tools that can make yard cleanup easy. Either type of equipment will help you remove leaves and other kinds of debris from your property far more quickly than a rake would.

But how do you know which one is better for you to buy? How do you know whether a lawn vacuum or a leaf blower will help you clean your yard or lot more effectively?

Read on to learn when it’s better to use a leaf vacuum and when it’s better to choose a leaf blower!
When to Use a Leaf Vacuum

For all the power they offer, leaf vacuums are usually the better choice for detailed work and for producing a finished look on your lawn.
Leaf Vacuums for Convenient Cleanup

Leaf Vacuum with Collection BagOne of the biggest advantages of using a vacuum over a leaf blower is the debris collection bag. When you vacuum your yard debris, the waste gets pulled into a vacuum bag. No shepherding stray leaves into piles, no need to bend over and scoop leaves—the leaves you wanted to clear are right there in a bag that you empty whenever it gets full.

Additionally, if you choose a push or a tow-behind yard vacuum, you’ll find that some models also can serve as litter vacuums, allowing you to pick up items like cans and food wrappers with almost no hassle.

Easy leaf (and litter) collection can be a major boon for people with limited mobility.
Leaf Vacuums for Making Mulch

Lawn Vacuum ImpellerInside of almost every lawn vacuum, whether it’s handheld or wheeled, is a component called an impeller. The impeller looks like a fan, but it does more than circulate air inside your blower. Its blades also chop up leaves and other debris into small pieces.

If you want to turn fallen leaves into mulch that you can spread over your soil for protection, a leaf blower is an excellent tool. Not only will it tear the leaves into tiny pieces that will decompose quickly and nourish your soil; its collection bag will also make gathering and distributing your new mulch material a simple task.

Similarly, vacuums are wonderful for breaking down and collecting leaves to add to a compost pile.
Leaf Vacuums for Careful Landscaping

Landscaping with FlowersIf you have roses and delicate flowers in your landscaping, you probably don’t want to expose them to the strong bursts of air that a leaf blower can produce. Doing so can risk damaging flower petals and thin stems.

To clean up the ground around your garden crops or landscaping showcase plants, use a leaf vacuum instead of a blower. Either a handheld vacuum or a push or tow-behind model with a small nozzle and vacuum hose attachment will provide you with the control you need in tight spaces.
Leaf Vacuums for Cleaning Other Narrow Spaces

Clear GutterThe spaces between plants aren’t the only spots that can benefit from cleanup with a leaf vacuum. Thanks to their nozzles, vacuums also are excellent for picking up dust and debris from gutters, window wells, and other narrow channels where a broad blast of air might scatter the debris too far.

(You can use a leaf blower to clean gutters as well, but be prepared for a few flying leaves!)
Leaf Vacuums for Pest Removal

Should I get a leaf blower or vacuum?

Japanese BeetleInsects happen. Whether you find Japanese beetles on your rose bushes or Colorado potato beetles on your backyard crops, you’ll need a way to get rid of plant-devouring insects before they multiply and decimate your annual growth. Catching them with a leaf vacuum is a pesticide-free way of getting them off your plants before too many appear.

Some horticultural professionals suggest using a wide nozzle to reduce the risk of the suction damaging your plants. And if you don’t want to harm any insect (or don’t want insects clogging the inside of your vacuum), you can fashion your own pest collection bag by securing a nylon knee-high stocking or other nylon cloth over the nozzle’s open end with a thick, strong rubber band.
When to Use a Leaf Blower

Yard vacuums are great for precision work. However, there might be situations in which you need to clear out a lot of debris. In these situations, a leaf blower will be the better choice.
Leaf Blowers for Quick Cleanup

Leaf Blower Pushing Large Pile of LeavesThere’s a reason why so many landscaping professionals can be seen carrying leaf blowers every autumn. Vacuuming leaves into a bag is convenient, but a vacuum’s suction force requires users to move more slowly than they would if they were pushing leaves ahead of them with a blower.

Thanks to both the volume of air that a leaf blower can expel through its nozzle and the speed of that air, leaf blowers are the tool of choice for people who need to clear leaves off a broad surface and into a pile quickly, which is often true for anyone cleaning up a large lot.
Leaf Blowers for Use with Other Equipment

Debris Loader Picking Up Large Pile of LeavesAnother detail that’s usually true for landscapers (or anyone who owns a large parcel of property) is that a leaf blower is only one type of tool at their disposal. Frequently, people responsible for enormous lots have an extensive collection of equipment that they regularly use.

A leaf blower is a great complement to other tools like debris loaders. Use the leaf blower to gather leaves into large piles, and then use the debris loader to remove the leaves from the property without having to stop to empty a bag.
Leaf Blowers for Wet Debris

Damp Leaves on the GroundThe power of a leaf blower’s airflow also helps when you need to clean up a lot of wet leaves and other kinds of damp yard waste. Vacuums can struggle to produce enough suction to pick up the heaviest pieces of wet debris; wet leaves inside your vacuum also risk clogging the machine, at least temporarily.

However, the force of air from a blower can be just what you need to get the mess on your lawn out of your way.
Leaf Blowers for Cleaning Open Spaces

Bed of Pickup TruckJust as leaf vacuums are great for cleaning narrow spaces like gutters and window wells, leaf blowers are great for cleaning open spaces other than your backyard or driveway:

Garages and workshops
Pickup truck beds
Insides of other vehicles (SUVs, vans, boats)

And yes, as mentioned before, as long as you don’t mind a little mess, they’re excellent for clearing gutters. No matter what you’re doing, be sure to be considerate to those around you!

Whether it’s a leaf blower or lawn vacuum, whatever the task you have ahead of you, having the right tool in your hands will spare you some strain and help you be more efficient when it’s time to clean up.

Are leaf blowers worth it?

Are leaf blowers worth it?

[av_textblock size=” font_color=” color=”]

Are leaf blowers worth it?

You’ve seen them at work in television commercials and your neighbor’s yard, but do leaf blowers really make that much of a difference? The answer is a loud and resounding, “Yes!” Leaf blowers are very versatile machines that are able to help simplify your daily lives immensely if you know how to use them properly.
They Cut Down on Time

Leaf blowers are extremely effective at what they do, and they have the ability to speed up your tasks like you’d never believe. Many people discover when they buy their first leaf blower that the power it generates allows you to take a job that normally lasts hours and complete it in just a few minutes. This feature alone is worth the buy because you’ll be able to spend more time with your family doing the things you enjoy.
They Save You From Aches and Pains

Using a leaf blower also means you won’t have to exert your body too strenuously. Instead of having to constantly bend down and reach for leaves that caught in the spokes of your rake or crouch down to reach for leaves that may have gotten stuck underneath the furniture in your lawn. All you’ll have to do is point the leaf blower tube at the leaf covered areas and direct them into an organized pile. Then simply clear the leaves away, or use the mulch and vacuum features on your leaf blower to clean up your yard.
They Pay For Themselves

Are leaf blowers worth it?

Buying a leaf blower can seem like a big investment and perhaps even a luxury item, but if you factor in the fact that the leaf blower will save you valuable time you’ll see that the machine really does pay for itself. If you divide the price by the number of minutes you spent using the machine, you’ll find that after a few uses, the price of the leaf blower will be equal to or lower than the price of a rake and trash bags.
You Can Use Them For Snow Too

Leaf blowers are very versatile and can be used for more than just clearing away leaves. They’re also great for helping to get rid of snow that’s overwhelming your driveway. They can be effective for clearing away snow if you’re in an environment that has dry and light snow. Anything that’s too wet or heavy likely won’t be impacted too heavily.

Using your leaf blower to clean out the snow in the driveway or off your car is only effective if there isn’t more than an inch or two of snow. Any more than that might be too heavy for your machine to move.

You’ll also need to make sure that if you do this you use the best gas powered leaf blower you can find. Any other power source could cause too much damage and poise a threat to your safety.
