DRV / DRH

For building ventilation

Can be assembled at an incline of up to 20° (available for bigger roof pitches upon request). The bellmouth is deep-drawn for the best flow properties and therefore enables high aerodynamic efficiency. The impeller is made of sheet steel, has backward curved blades and is dynamically balanced. The fan has an external rotor three-phase or alternating current motor and a closed design with moisture protection insulation. The motor is fully protected due to guided-out thermal contacts embedded in the motor winding
