DKA TECHNICAL DOCUMENTATION Function and use | Accessories FUNCTION AND USE The round, manually adjustable damper DKA is suitable for installation in round supply air and return air ducts according to DIN EN 1506. It is used for regulating the volumetric flows in air-conditioning installations. The hand-adjustable device with integrated position indicator allows an exact setting of the damper blade, without tools, between 0° and 90°. The housing is dimensionally stable due to standard double beads. For use with airtight locking of volumetric flows, the damper DKA-L must be used. The damper type...

DKA TECHNICAL DOCUMENTATION Technical data | Legend Correction factor for noise level Lwa1 [db(A)] The leak volume with closed damper is approx. 5%, relative to the volumetric flow with open damper and at the same differential pressure. Duct velocity LEGEND Vzu (m3/h) = Supply air volume = Supply air volume = Duct velocity = Pressure loss = A-weighted sound power level (Lwa Lwai + KF) = A-weighted sound power level relative to NW 160 = Correction factor = Damper position = Nominal width = Length = Position of damper blade axle = Diameter Construction subject to change No return possible
