The DSQWA rectangular multiblade aluminium dampers can be used to control and isolate air flow in rectangular ductwork. The dampers can be installed in ventilation ducts, as wallmounted air flow regulators, or AHU air flow regulating and shutoff units. All dampers have a housing made of 4 aluminium profiles and a closure consisting of aluminium blades. The blade height is the same for all product sizes. The blades are fitted with gaskets to provide air tightness class 2 as per EN 17512003. The DSQWA damper can have a handoperated damper mechanism QDMPSAL, an externallymounted actuator, or an actuator mounting. The damper mechanism is installed on the outer surface of the housing. The damper blade rotation mechanism features short and long shafts rotating by intermeshed gears installed on bearings. The gears are installed on the outer surface of the housing.
