Rectangular fire damper Rectangular re dampers CU4 are installed in ventilation ducts passing through a construction element in order to stop the propagation of re. They dispose of a modular operating mechanism positionned completely outside the wall. The rectangular re damper CU4 has a re resistance up to 240' and was tested at 500Pa. The refractory casing is asbestos free and resistant to humidity. The re damper can be equipped with a common fusible link mechanism up to a motorized mechanism. 9 • Tested according to the European standard EN 1366-2 at 500Pa • Suitable for mounting in rigid wall...

Rectangular fire damper CU4L Elongated tunnel The CU4L damper is a CU4 damper of which the tunnel is extended to one or both sides Applications: - The damper can not exceed one or both sides of the tunnel - To allow an easy connection in case of a thick wall - To allow the installation of a grill directly on the tunnel of the damper x = elongation on the side of the mechanism y = elongation on the other side of the mechanism x of y>0 Rigid wall ve = damper mounted directly in the wall ho = damper mounted directly in a floor/ceiling i o = fire can come from either direction Pa = Pascal E = integrity...
