Backward Incline Centrifugal Fans

Centrifugal fan is a constant CFM device or a constant volume device, meaning that, at a constant fan speed, a centrifugal fan will pump a constant volume of air rather than a constant mass.

This means that the air velocity in a system is fixed even though mass flow rate through the fan is not.

Centrifugal Fans are not usually good for higher static pressures.

Backward Inclined Blowers are an excellent choice for centrifugal fan applications that require high volumes of air and pressures
