Cubic Feet per Minute (CFM) represents a unit of measurement indicating the volume of air a leaf blower can move. A higher CFM rating signifies the tool’s capacity to displace a larger quantity of air within a given minute. As an example, a leaf blower with a rating of 400 CFM can move 400 cubic feet of air every minute.
The significance of this measurement lies in its direct correlation to a leaf blower’s clearing power and efficiency. A higher volume of air flow translates to a greater ability to lift and move leaves, debris, and other materials across a surface. Historically, this measure, combined with airspeed (measured in Miles Per Hour or MPH), has become a crucial factor in evaluating and comparing the performance capabilities of different leaf blower models. The combination determines how effectively the tool clears various types of debris and the area it can cover.
