CU2+CFTH : Rectangular fire damper CU2 with the unlocking mechanism CFTH. It automatically unlatches the damper blade when the temperature in the duct rises above 72ºC. due to the rise in temperature the fusible link melts. This causes an armed internal torsion spring to unwind and thereby release the damper blade into its safety position (closed). The fusible link must be replaced after functioning.

the damper can be unlocked manually to test the proper functioning of the mechanism. The damper must be reset manually.
