When shopping for a new blower, many consumers look at the “miles per hour” rating to assess the power of a blower. However, it is possible for a 230 MPH blower to have more power than a 240 MPH blower. Here is why:
MPH alone is not a good measure of power
A blower nozzle opening the size of a straw could blow air at 300 mph—it is good for clearing out cracks in the driveway, but not good for blowing leaves in your yard. Many of the tasks you expect to accomplish with your blower require both air speed (MPH) and air volume (CFM or cubic feet per minute).
CFM alone is not a good measure of power
A blower nozzle opening the size of basketball could put out 600 CFM of air—it is great for sweeping dust and sand off a driveway but without sufficient pressure, it would have a difficult time moving anything else.
You need both air speed and air volume
The most powerful blower will be one that maximizes both air speed (MPH) and air volume (CFM). Rather than reduce the size of the blower nozzle to achieve higher MPH ratings like some manufacturers, Toro engineers strive to provide an optimum balance to maximize the performance of our blowers and blower vacs.
What does more power mean?
Chores done faster and more effectively!
