1. An Overvew of Centrifugal Fan With Backward Curved Blades
(1)Description
Backward curved centrifugal fans are used primarily for intake suction and do not require a scroll housing. They have high hydraulic efficiency. They usually offer a quiet and compact air moving solution. The Permanent Split Capacitor motors provide reduced operating costs and longer service life. Ball bearing construction allows multiple mounting options. Backward centrifugal fans have low profiles that do not need scroll housing. Air is discharged 360° radially from the impeller wheel. These units operate very efficiently at high pressures.
