Introduction

The CSS circular smoke and fire damper
is the latest development to join the
Actionair’s 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.
