What does MPH mean on a leaf blower?
Leaf blower miles per hour (MPH) Explained simply, this is the speed of air coming out of the leaf blower in miles per every hour. The idea is to inform us how many miles the air will travel if the speed remains the same for a full hour. It is comparative to measuring the speed of most moving objects.
What should I look for when buying a leaf blower?
Leaf Blower Features A high CFM will let you blow many leaves at once, while a high mph will move heavier debris or wet leaves. If in doubt, opt for a model with a higher CFM. Look for a leaf blower that feels balanced in your hand and moves and adjusts easily.
Is 300 cfm enough for a leaf blower?
The CFM of residential leaf blowers usually tops out around 1,000, with most of them moving in the 300-700 range. Whereas commercial (walk-behind) models are usually closer to 2,000 to 3,000.

What is a Good CFM for A Leaf Blower? – Chainsaw Journal
Walk behind wheeled leaf blowers. The walk-behind leaf blowers deliver the biggest punch but it’s built for a specific environment. A good CFM for a wheeled leaf blower ranges from 1080 cfm at 200 mph to 2600 cfm at 200 mph. The walk-behind model is most effective for wide-open spaces, like parks.
What does MPH mean in leaf blowing?
MPH tells us how fast the air exits a leaf blower.
What is the function of a leaf blower?
A brief rundown of the leaf blower’s function. The engine of a leaf blower creates force. The force acts upon the surface of wind – in other words, pressure is created. The force is a constant – it does not depend on the size of the surface.
What is CFM and MPH?
The two specifications that characterize a leaf blower’s “ability to blow” are the cubic feet per minute (CFM) and the miles per hour (MPH).
How to achieve a decent velocity with decent diameters?
In order to achieve a decent velocity with decent diameters, a sufficient CFM is needed. Thus, if the CFM seems suspiciously low compared to MPH, the manufacturer most likely boosted the MPH by decreasing the diameter of the pipe. This results in the above listed straw effect.
What is the highest CFM on a Billy Goat?
For the highest CFM, the Billy Goat F1802V, with a CFM of 2900.
Why is higher CFM important?
They are both important and distinct metrics. A higher CFM will help you clear a larger area and push leaves further. A higher MPH will help you better lift wet leaves and debris.
What happens when you blow a straw?
Two things happen: Even if you blow with the same force, you will notice a dramatic increase in velocity of the air exiting the straw. You have decreased the area through which the air is flowing. Even though you are now blowing faster, you will have tough time reaching all the candles on the cake.
What is a good CFM for a leaf blower?
A leaf blower with up to 500 CFM rating is going to provide enough airflow to blow a decent volume of leaves with ease. At the same time, a leaf blower in this CFM range will be easy to handle around confined spaces. Leaf blowers under 500 CFM are usually handheld making them perfect for small areas such as patios, lawns, and backyards. Generally, handheld leaf blowers have an MPH rating of around 100 MPH which is a great combination for this CFM range. Almost all of the leaf blowers in this range are battery powered cordless units which means you can only use them for a fixed amount of time until you run out of battery. But with an area under an acre, you will notice that a battery-powered leaf blower provides enough battery life to get the job done.
What does CFM stand for in leaf blower?
CFM stands for cubic feet per minute and it tells us the volume of air that comes out of the leaf blower’s nozzle in one minute.
What is the Newton force rating of a leaf blower?
It can be confusing to interpret CFM and MPH ratings when buying a leaf blower. Not to mention that leaf blower manufacturers usually boast one rating while keeping the other hidden when advertising their products. Because of that, people end up looking at only one rating while ignoring the other. For example, if a leaf blower has 200 MPH written on the package and the CFM rating is not clearly mentioned, people, will focus on the MPH rating while the CFM rating of the same leaf blower might be too low. Even if a leaf blower has both of the ratings mentioned clearly, you never know under what circumstances these ratings were measured. For example, a leaf blower will show a high CFM rating if the test is taken with the nozzle removed. Still, in the real-world scenario, the CFM with the nozzle attached matters since we will not use a leaf blower without its nozzle attached.
What is an ideal CFM and MPH rating?
There is no fixed rule for how much CFM and MPH a leaf blower should have. Instead, both of these ratings depend completely on how and where you intend on using the leaf blower. Some leaf blowers will have a higher MPH rating but a lower CFM rating, while others might be the opposite. So you have to pick the leaf blower as per the size of the area and the type of debris you want to push. Below are some general guidelines about how much CFM rating a leaf blower should have according to the size of the land it is going to be used on:
What is the best leaf blower for a large yard?
If you have a bigger yard with an area well above an acre in size, you will have to look for a leaf blower with a CFM rating of upwards of 500 CFM. Because the area to be cleaned gets bigger, so does the amount of debris that needs to be pushed. Not to mention with a bigger yard, you will be pushing leaves for longer distances to clean the area. Therefore you need higher CFM to tackle this situation. Leaves tend to pile up quickly in a larger yard, which means the leaf blower will be pushing heavier debris, so any leaf blower under 500 CFM rating will make the job really difficult in a yard that is well over an acre in size. So it is recommended to buy a leaf blower with a CFM rating of around 650 CFM and an MPH rating above 200 MPH for a bigger yard. You can get a leaf blower with up to 800 CFM range if you want to, but it will be more expensive. Of course, you can’t expect this kind of performance from a battery-powered leaf blower which is why all the leaf blowers in this CFM range are either electric or gas-powered. You can run these leaf blowers for longer to cover larger yards with ease.
How to tell how strong a leaf blower is?
If you want to know how strong the air that is blown from a particular leaf blower will be, then you need to look at the CFM rating of that leaf blower. This is because more air coming out of a nozzle means you should blow the debris further. So to summarize everything, you can take the CFM rating of a leaf blower as the ability of a leaf blower to push leaves using the airflow it produces. But CFM alone can’t tell you everything about a leaf blower when buying one, which is why you have to look at the MPH rating of a leaf blower as well.
How much air does a leaf blower blow?
But as a matter of fact, CFM is an equally important metric to consider if not more important than MPH. If you want to have an idea about how much air a leaf blower puts out, then CFM is the metric you need to look at. For example, if a leaf blower has a CFM rating of 300 CFM it means that it will blow 300 cubic feet of air every minute while it is running. CFM also tells you how much debris and leaves can you blow using a leaf blower and how wide the blow of air is going to spread. You are also going to notice that leaf blowers with higher CFM ratings have wider nozzles while the ones with lower CFM ratings have narrow nozzles. That is because a larger volume of air requires a wider nozzle to pass through and blow out.
What is CFM in leaf blower?
When discussing leaf blower CFM you get into the talk about volume. CFM refers to how much volume of air – measured in cubic feet – leaves the blower every minute.
How fast is air coming out of a leaf blower?
Explained simply, this is the speed of air coming out of the leaf blower in miles per every hour. The idea is to inform us how many miles the air will travel if the speed remains the same for a full hour.
Why is my leaf blower not blowing leaves?
Why? Because due to the tiny nozzle (maybe the size of a straw) it does not produce a good amount of air displacement to blow leaves away. In this instance, we have a high mph but a very low cfm.
What does 100mph mean?
When talking about a leaf blower, if the speed is 100mph, it means that the air will travel 100 miles if the speed of the blower remains the same for one hour.
How fast does a blower blow leaves?
The blower would definitely blow a lot of leaves away. This is because the exit of the blower produces a lot of air displacement at the high speed of 150mph.
Is 30 mph good for leaf blowing?
As you can imagine, even though the nozzle is huge enough to carry out a lot of air displacement, the 30mph speed of air is not good enough to help blow away anything. In this case, we have low MPH vs high CFM.
Is 100 mph better than 30cfm?
If you get a blower said to have 100mph and 30cfm, that does not make sense. 100mph would ideally have closer or more than 100cfm. This is not to imply that the CFM should be equal to mph. Because in some leaf blowers, you will find specifications like 150mph and 250cfm. Others will have 180mph and 600cfm. This is good because the CFM is indicative of great power. However, in the first example of 30cfm, you can bet there is no useful power in that leaf blower even if it had so much airspeed.
What does MPH mean on a leaf blower?
To sum it up, MPH is an indicator of the speed at which air comes out of your leaf blower. It, however, does not indicate anything other than the speed – so you don’t know how much air is coming out or anything else about it.
How is a leaf blower rated?
Leaf blowers are rated by the amount of air they move which is measured in cubic feet per minute (CFM). They are also measured by the speed at which they move that air measured in miles per hour (MPH). Larger more powerful blowers can move more air faster than smaller blowers but the tube size and shape play a role as well.
What is the difference between CFM and MPH?
In some ways CFM is like the flow of water in a hose and MPH is like the pressure of the flow measured in PSI, the speed at which the air is flowing gives a blower it’s strength but if CFM is low that strength will be isolated to a very small space. There are very specific reasons why this may be desired however but in most cases regular homeowners ...
Why won't my blower come out as quickly?
Once the exit tube is widened the same amount of air or more can exit the blower but it won’t come out as quickly because it doesn’t need to. To keep the velocity up the motor has to work harder and harder and with small outdoor tools the tool would have to get bigger, bulkier, and more expensive to keep up with the MPH demands as the CFM output increases.
Why are leaf blowers so expensive?
There’s a reason why the best leaf blowers on the market are expensive. To get high CFM and MPH ratings the machines simply cost more to produce. For battery blowers with high CFM specs the cost can get quite high indeed.
How does a blower work?
Most blowers work based on a motor or engine turning an impeller or a turbine. As the impeller spins air is sucked into the unit through a set of vents usually near the motor or handle. The blades then propel the air through a narrow shaft which increases it’s velocity at the exit point.
Why is CFM important?
Why CFM Is More Important (Most of the Time) In the vast majority of cases a blowers ability to push more air out ( CFM) is more important than any other factor… so long as velocity (MPH) remains high enough to actually move materials on the ground. Most people use leaf blowers to gather leaves or to move leaf piles in the fall ...
What is the difference between a CFM and a MPH?
CFM is more about how much air is pushed through the unit and out the nozzle. Where MPH is the speed at which it is pushed . One is like getting hit by an air compressor hose and the other is like sticking you head out a car window. The difference is can change the dynamic of how well your leaf blower does what you want it to do.
How fast can a 500 CFM battery run?
A 500 CFM model might put out no more than 160 MPH of air force. The battery will last about on hour at best, depending on the size. Once again, great for home, but not good for professional landscaping, unless you have lots of batteries and patience.
What is the difference between mph and cubic feet per minute?
Because cubic feet per minute is a measurement of volume, and miles per hour is a measurement of wind speed, CFM is the determination of how much area is covered in the span of 1 minute, where MPH is how fast that area is covered.
How many Newtons does a backpack gas blower have?
Cordless blowers hover between 8 and 17 Newtons, where as backpack gas models push between 28 and 39 Newtons. This gives you a different perspective if you were still a little confused.
What is the best CFM for a sandbox?
The best CFM is midrange between 350 to 600 CFM, blowing north of 190 MPH. Too low will not do the job, too high and you lose control of the leaves, making the job take longer.
Do you need blisters for a leaf blower?
Thank goodness those days are gone with the invention of the leaf blower, a powerful, directional tool that does much of that work, no blisters necessary. But while having a leaf blower might be sufficient, having the right leaf blower for your specific application is more important for the overall efficiency of the task at hand. And there are some big questions you must ask yourself before picking one, blowing power being chief among them.
Do you read reviews before buying a leaf blower?
We all read reviews before we make a purchase like buying a new leaf blower, weed whacker, or similar types of outdoor equipment. But one thing that many professionals pay even more attention to are the details they know make a bigger difference than the average consumer’s opinions, and that is hard data from the source.
Leaf Blower CFM vs MPH: Which is More Important?

Other factors like the design of the impeller blade and the leaf blower’s weight factor into the CFM and MPH values. Each type of leaf blower—handheld, backpack, or walk-behind—has its own set of CFM and MPH ratings.
Why is CFM important?
But why is that number important? Knowing the CFM allows the buyer to determine how big of an area they can clear in a period of time. The higher the CFM the more air that passes through and the more debris is moved. Generally speaking, the larger the mouth of the nozzle the more air will blow through, making the CFM higher.
How does a leaf blower change the CFM?
The nozzle is the key to changing both the CFM and MPH on a leaf blower. If the nozzle is narrower, the MPH will increase because the air has less room to expand. So, it will blow with more force. However, this decreases the CFM.
What does CFM mean in leaf blower?
Cubic feet per minute (CFM) measures how much air flows through the leaf blower each minute. The higher the CFM the more air your leaf blower produces. This number determines how big an area can be cleared in any length of time. Miles per hour (MPH) determines the speed of the air flowing through the nozzle. The higher the MPH the faster the debris is moved.
How is CFM determined?
Usually, CFM and MPH are determined by the leaf blower’s engine. The larger and more powerful the motor the higher the CFM and MPH will be.
What are the different types of leaf blowers?
