Application
Roof fans are used for overall ventilation or local extraction. They are reliable and efficient in application with ventilation systems and extraction units because of the increased fan pressure compared with traditional roof fans.
Structure
The fan consists of spiral housing, radial impeller, flange-motor and conic steel-hood. The fan outlet is equipped with a silencer. The fan can be installed on a roof base or a special wall bracket trough a flange-ferrule at the fan’s inlet.
