The DSQW-A rectangular multi-blade aluminium 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 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 1751:2003.
