The casing of the damper is made of corrosion-protected steel sheet. Certification according to EN 15650. Classification according to EN 13 501-3+A1. Fire resistance of the damper is EI90 or EI120 according to the installation method. Tested according to EN 1366-2 at 500 Pa.
Use
Fire dampers can only be used for air free of mechanical and chemical impurities and in environments without explosion hazards.
Variants
The fire damper is available in the following versions. With fusible link (type CFTH), which activates the closing mechanism at temperatures above 72 °C, or with actuator (type ONE/BFL(T)/BFN). The actuator can be fitted with a 24 V or 230 V actuator. The damper is fitted with a UL inspection opening. On request, dampers with an extended length of 500 mm or ATEX certified can be supplied.
