CFDM fire dampers are diaphragms in ducted ventilation systems that prevent the spread of fire and products of combustion from one fire segment to another by closing the air duct at points of fire separation structures. The damper diaphragm automatically closes the air duct with a closing spring.
LE flexible coupler
Flexible couplers are used to eliminate vibrations transmited from the fan of other ventilation devices to the ventilation system, as well as to compensate to some extant the ventilation ducts resulting from temperaturę elongation. It is used in ventilation devices in temperatures ranging from -40oC to +80oC.
