Supply fan with integrated pressure relief damper (mechanically regulated)

Type: DV-RK1

• Supply fan with integrated pressure relief damper (mechanically regulated)
• For the maintenance of an overpressure of max. 50 Pa in the pressure zone
• The automatic regulating pressure relief damper fulfils the control time requirements of DIN EN 12101-6, a direct reaction on opened up and closed doors are therefore given.
• At closed doors the backflow of the volume flow happens backwards over the open damper
• At opened doors from the pressure zone and the given exhaust flow possibility
• From using to the atmosphere the damper is closed und the volume flow is available for the perfusion of the open door cross-section
• The unit should be installed blowing out freely into direct contact to the pressure zone, external pressure losses are to restrict to < 25 Pa
• Different installation locations are to check with the manufacturer
• Construction form of the ventilator: Axial ventilator with an infinitely variable blade angle and characteristic stabiliser in the shutdown
• The characteristic stabiliser prevents the shut-off of the characteristic in the left area. So we guarantee a secure handling at changing system conditions
• Available frame sizes see selection table
• Constructions with weather protection case on request
