Leaf Blowers & Yard Vacuums: CFM vs. MPH

Do you know why high CFM is essential for moving wet heavy autumn leaves, how metal shredder impellers reduce leaf volume, and how brushless fans operate?

Clearing wet autumn leaves and heavy pine needles requires high air volume (CFM) combined with sufficient air speed (MPH). Understanding impeller mulch ratios ensures peak blower performance.
