Gasket air - Import export

Pressed bends are designed for building ventilation systems based on spiral and plain ducts. Seam welds provide air tightness class D without the need to use any other sealants. In ventilation and heat recuperation systems, the double EPDM gasket provides air tightness class D according to EN 12237. The piece is connected with a duct by inserting one into the other. The pressed form of the ventilation piece helps to reduce the flow resistance and the pressure loss.

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.
