Fans

RULA design, manufacture and supply fans for a wide range of Bulk Materials handling applications

Description

A centrifugal fan is a mechanical device for moving air. Centrifugal fans are constant displacement devices or constant volume devices, meaning that, at a constant fan speed, a centrifugal fan moves a relatively constant volume of air rather than a constant mass. This means that the air velocity in a system is fixed even though the mass flow rate through the fan is not.
