Do You Have Enough CFM? How to Measure Leaf Blower Power.

0

Technology for outdoor power equipment is continuously advancing and every new leaf blower seems to have more power than the last. But how do you know if you have enough leaf blower power for you? Or, how do you know if a leaf blower has too much power? To know this you need to understand the main components of measuring leaf blower power, which are CFM and MPH.

Today, we are breaking down these components for measuring leaf blower power and helping you gauge the correct power level for you.

Leaf Blower Power Guide

How is Leaf Blower Power Measured?

Leaf blower power is based upon two main measurements: CFM and MPH. The power level also relies on the leaf blower’s overall voltage and power source. Let’s break each of these components down to understand them individually, as well as how each component impacts each other.

What is CFM?

CFM stands for cubic-feet-per-minute and this measurement refers to the amount of air moved in one minute and CFM is measured with an anemometer. Fans and air compressors also use this measurement, but for leaf blowers this measurement refers to the amount of air being pulled in and exiting through the blower over the course of a minute.

To put it simply, the higher the CFM, the more leaves and debris that can be moved in one minute, theoretically…

MPH

Miles-per-hour (MPH) is the other measurement used to calculate leaf blower power. This is a straightforward measurement that most people are used to. For leaf blowers it refers to the rate of speed at which air exits the blower.

One would assume a high CFM would create a high MPH. CFM definitely impacts MPH. However, MPH can be manipulated based on how wide or narrow the tube or nozzle is.

The Husqvarna Leaf Blaster™ Blower we recently reviewed is a great example of this. The high-speed nozzle is narrower, and that tighter concentration of air increases the MPH.

With that in mind, high CFM does not necessarily equate to high MPH. Buyers need to pay attention to both units of measurement.

Power Source

Gas and electric are the two main power sources for leaf blowers. Now, these two power sources are measured differently. Gas is measured in cc’s and electric is measured in voltage, and both play a significant role in the engine’s power and the resulting CFM and MPH.

Gas vs Electric

Power source is another important factor when determining a leaf blower’s power.

Over the years there has been a steady rise in electric leaf blowers and outdoor power equipment (OPE). However, many consumers still use gas-powered blowers. Both sides make claims about which is better. To me, neither is better, but they’re different.

Here are a few quick facts about each type of power source so you can decide which is best for you.

Gas

  • Generally more affordable/lower upfront cost.
  • Added expense of gas and oil.
  • Requires regular maintenance.
  • Arguably longer or higher power performance than most battery equivalents, plus quick and easy refueling.
  • Loud when in use.
  • Two-stroke fuel-burning is a known pollutant and carcinogen.

Electric

  • Choice of corded or electric.
  • Generally more expensive/higher upfront cost.
  • Has renewable power source.
  • Requires minimal maintenance.
  • Shorter runtimes for battery-powered and may need multiple batteries to complete one area. However, battery recharge times are improving.
  • Generally quieter than gas-powered leaf blowers.
  • Arguably more environmentally friendly.

Based on current OPE battery technology, most homeowners can have their lawn and garden needs met with electric-powered leaf blowers and OPE.

How Much Leaf Blower Power Do I Need?

How much power you need will depend on what you need a blower for. Before purchasing, ask yourself:

  • Is this leaf blower for personal or commercial use?
  • How big is the area that I will regularly use this for?
  • How often will I use this leaf blower?
  • What is my budget?
  • Do I want a gas or electric leaf blower?

A shopper with a small yard who only needs a blower for weekly maintenance obviously needs less power than someone with a large yard with lots of trees or multiple areas to maintain. Once you figure out where your needs fall you can then gauge the appropriate level of CFM for your needs.

Here is quick almost cheat sheet for knowing how much power the average person needs in these common settings.

  • 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.
  • 600-800 CFM: Ideal for landscapers or property owners with a lot of brush. This power level can be found in 40-80V leaf blowers.

Types of Leaf Blowers

There are three main types of leaf blowers: handheld, backpack, and walk-behind.

Handheld leaf blowers are the most common type of leaf blower, especially among everyday consumers since the price and performance meet the needs of the average homeowner. Backpack and walk-behind leaf blowers are more common in commercial settings, or those with large and/or multiple properties to manage.

Buying your first leaf blower can be intimidating if you’ve never dealt with CFM’s or don’t know the difference between a volt and a cc. However, if you just sit down and take a moment to understand what these measurements mean it turns out it’s really not that complicated.

I hope you learned something today and are one step closer to finding the leaf blower that works for your life.
