The DSQW rectangular multi-blade dampers can be used to control and isolate air flow in square ductwork. The dampers can be installed in ventilation ducts, as wall-mounted air flow regulators, or AHU air flow regulating and shutoff units.
All dampers have a housing made of 4 galvanized steel sheet profiles framed with PQ angles, and a closure consisting of aluminium blades. The blade height is the same for all product sizes.
DSQW damper valves can be controlled by a manual mechanism or, after removing the handle, adapted for an actuator. The damper mechanism is installed on the outer surface of the housing. The damper blade rotation mechanism features short shafts and installed on bearings.
Operating temperature: -20˚C to +80˚C.
