The CSS circular smoke and fire damper is the latest development to join the Actionairs innovative and tested range of damper products.
The damper has been developed for installing into standard circular spiral duct systems where the duct passes through, up to 2 hour rated walls. The easy fit flange system makes the installation quick and simple.
The CSS is available in a number of circular sizes to suit 50mm thermal insulated or non insulated ductwork, and is supplied with a factory fitted control mode, with Electrical Thermal Release (ETR) as utilised on our Smoke, Vent / Shield ranges.
