METALDETECTORS BASIC FAN LAWS

Fan efficiencies remain constant for symmetrical design. Whenone or more conditions change, the other conditions varyaccording to certain fan laws for an established fan size, systemof ductwork and air density.

1. Fan’s air-delivery will vary directly as the RPM ratio.

2. Developed fan pressures will vary as the RPM ratio squared.

3. Horsepower absorbed by fan will vary as the RPM ratio cubed.
