Roof Mounted Centrifugal Fans

Roof Mounted Centrifugal Fans

Our centrifugal roof fans are available in either vertical or horizontal discharge, depending on the setting. They can be mounted to almost any design of roof including saddle roofs, flat roofs and pent roofs. The DH models are best for less polluted, clean air as opposed to the DV which is best for dusty or contaminated air.

A choice of AC, EC and IEC motors are available, all of which offer noise attenuating versions.
