What is a good CFM for a leaf blower? A good CFM for most yards ranges between 400-700, depending on the size of the area you need to clear. However, 150-400 CFM should do the trick for smaller yards.
The only number to keep an eye on is CFM. 750+ is needed if you want to replace a rake. 400 CFM is useful for blowing around trees and other little stuff.
400 CFM minimum if you're using it to move leaves. Preferably 600+.
250 CFM is enough to blow sidewalks, small yards, and most debris. 2 Ah battery lasts for about 15-20 minutes continuous and charges in about an hour. The blower is very lightweight and easy to use. Indicator lights to show charge volume on the battery.
You should look for a blower with 450-500 CFM and 150-190 MPH ratings.
If you have a small yard with little debris, choose one with 200-400 CFM. Our knowledgeable sales staff can help you determine a good CFM and MPH for your needs, whether for commercial or residential landscaping. (There are commercial leaf blowers with a CFM of up to 3,000!)
High CFM: If you need to clear large areas with a lot of leaves and debris, a leaf blower with a high CFM is more efficient. It will move more at once, saving you time and effort. High MPH: A high MPH leaf blower is your best bet if you're dealing with wet leaves or stubborn debris.
Small Yards (Up to 2,000 sq. ft.): A blower with 150-200 CFM is generally sufficient for light debris and routine maintenance. Medium Yards (2,000 to 5,000 sq. ft.): Look for a blower in the range of 200-400 CFM to handle a moderate amount of leaves and debris effectively.
Ducted Range Hoods for Electric Cooktops
Wall-mounted & Under-cabinet range hoods – 100 CFM for every linear foot of cooktop. Most common types of cooktops measure 30 inches wide or 2.5'. To meet the recommended CFM requirements, you'll need a range hood with 250 CFM.
What is a good CFM for a fan? This entirely depends on the application. For a residential fan you might have in your living room, a CFM of 5,000-6,000 might be totally sufficient. For large warehouses, you might want a fleet of large-diameter HVLS fans that each have a CFM of over 300,000.
Internet says anything north of 400 CFM. I've used the battery powered Milwaukee blower at work and it did pretty good. Was not too heavy... Maybe ten pounds with the large battery, you can drop that weight if you use smaller batteries. And you could lock it powered on.
450 cfm and 600 cfm are directly comparable, with 600 cfm being 33% more air by volume than 450 cfm. This measurement down not take into account the velocity of the air coming out of the nozzle.
If you're looking for the most powerful cordless leaf blower, go for EGO's 765 CFM model. Using a 5.0Ah battery, it hit 25.3 Newton on our meter. Stepping up to a 10.0Ah battery, it hit 26.1 Newtons!
Often, a ventilation power varying between 350 CFM and 500 CFM is sufficient, depending on your cooking habits. For example, if you are used to using many rings at the same time, you will require a higher ventilation power.
Blowers: Air Volume and Speed
The first is cubic feet per minute (cfm), which measures the volume of air produced, and miles per hour (mph), which measures air speed. The higher the cfm rating is, the more leaves you'll be able to blow at once. The higher the mph rating is, the farther you'll be able to blow them.
Walk-behind leaf blowers (also called push blowers) are designed for the heavy-duty landscaping jobs. They have the power to clear leaves and debris.
200-400 CFM: Great for homeowners with average-sized yards. This power level can be found in 18-24V leaf blowers. 400-600 CFM: Perfect for people with larger lots such as homesteaders, landowners, and property managers. This power level can be found in 40V leaf blowers.
The Husqvarna Leaf Blaster 350iB Cordless Leaf Blower has the longest run time of any cordless leaf blower we've tested, and unlike a lot of others, it matches that longevity with a substantial amount of power.
How to calculate the cfm of the blower? You can use the formula: CFM = (fpm * area), where fpm is the feet per minute. At the place of the FPM value, input the area after it is squared.
The speed of the air as it leaves the leaf blower is measured in miles per hour (MPH). This is another way to measure how powerful the leaf blower is. A leaf blower that's capable of blowing air at faster speeds will be more powerful and be able to blow away heavier objects.
