Roof and Duct Fans

Roof and Duct Fans

The fan is another element which, apart from the AHU unit, controls the amount of the air diffused and exhausted indoors.

Depending on the needs, it is a duct or axial type fan, available in a polypropylene or sheet metal enclosure. The available diameters range from 100 to 315 mm, depending on the fan type and power.

The roof fans and the PD-B3 roof bases can work as independent ventilation units, e.g. for industrial rooms.
