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 EI60, 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 CU-LT fire damper is available in the following versions. With a fusible link (type MFUSP), which activates the closing mechanism at temperatures above 72 °C, and a servo drive (type ONE/BFL(T)).
