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.
TLE flexible acoustic silencers
A flexible TLE acoustic silencer is made of a perforated duct. The applied insulation is 25mm thick and covered with an aluminium-polyester jacket. The silencer is connected with metal flanges acting as a nipple. These are available in two lengths, 600mm and 1,200mm. Upon request, it is possible to manufacture silencers: with EPDM
