Roof Fan

Roof Fans

There are 2 types of roof fans: type DH/DHE with horizontal discharge (as can be seen in the picture to the left) and type DV/DVE with vertical discharge. Both of which are suitable on shed roofs, saddle roofs, flat roofs and pent roofs. The DH/DHE models are bet for less polluted air as opposed to the DV/DVE which is best for heavily contaminated air.

The DV/DHE model is available in both AC and EC variations, there is also an IEC motor version with the code DVWN. The housing of a DV model (vertical discharge) is made of seawater-resistant aluminium.

The DH/DHE (horizontal discharge) is available in AC and units up to size 500 have a protection cover for rain made out of seawater-resistant aluminium. Anything larger (from 560) has a rain protector made of galvanised sheet steel.

 

Commercial Roof Fans

Both are fitted with backward curved impellers made of plastic. AC products are ERP 2016 compliant, the EC models are ERP 2018 compliant.

The inlet nozzle in the base frame protects the duct against water ingress. The mounting screws ensure easy of the accessory on to the fan.  The motor carrier cage is a plastic coated round wheel and has been created with bird and contact protection. Their speed is 100% infinitely variable by using an auto transformer.

IEC Motor Variations (DVWN) can be operated up to 120 °C as the motor is outside of the airstream. The fans are driven by IEC three phase motors and up to size 450 are suitable for voltage control. From size 500 the fans are controllable with a frequency converter.

AC, EC and IEC motor models are all available in sound attenuating versions. ATEX versions are available on request.

Applications

Applications include but are not limited to warehouse ventilation, supermarkets ventilation, factory ventilation, swimming pools ventilation, gymnasium ventilation, garage ventilation, agricultural ventilation, stable ventilation, farm ventilation, commercial building ventilation, industrial building ventilation, residential building ventilation, toilet and bathroom ventilation and much more.
