DEFINITION
The
Stockbridge Airco belt driven fan type DIDW is a high volume
centrifugal fan with either aerofoil (CBA) or laminar (CBL)
impeller. The more commonly used aerofoil impeller is specified
for heating and ventilating applications on clean air/gases.
With a relatively low fan height, the DIDW is the ideal compact
air mover for packaged air handling units (AHUs).
The
range of CMB fans is supplied in sizes from 300 mm to 900
mm, handling pressures up to 750 Pa and volumes up to 43,000
m3/hr. Bespoke variations can also be supplied.
