How does a vacuum blower work?

A vacuum blower, whether for leaf or industrial applications, uses a rotating impeller (or rotor) to create a vacuum. This vacuum pulls air (or gas) into the blower, and the impeller’s rotation then forces the air outward with increased speed and pressure. This pressurized air stream can be directed for various purposes, like clearing debris or conveying materials.

This video explains how a leaf blower/vacuum works, including the impeller and mulching function:

۱٫ Air Intake: The blower’s design includes an inlet that draws air or gas into the device.

۲٫ Impeller Rotation: Inside the blower, a rotating impeller (or rotor) acts as a fan.

۳٫ Centrifugal Force: As the impeller spins, it generates centrifugal force, which pushes the air outwards towards the impeller’s blades.

۴٫ Increased Pressure: The air is accelerated by the impeller blades and its volume increases within the blower’s housing. This increase in velocity and volume leads to a buildup of pressure.

۵٫ Air Discharge: The pressurized air is then channeled out of the blower through an outlet, creating a directed airflow that can be used for various tasks.

In essence, the blower converts rotational energy into air pressure, creating a focused airflow for blowing or vacuuming purposes.
