UL-listed Fire Damper

Motorized (electric, pneumatic, or manual operation), leakage Class I, high temperature, high pressure, UL-listed fire damper, also for explosion-proof hazardous areas.

Dampers 

It is a high-performance, low-leakage, robust, high-temperature UL-listed fire-damper. It is used in air-transfer- openings, in wall openings, in ducts, and in other places. where fire-rated structures (e.g., walls, floors, or other fire barriers) are penetrated. The idea of compartmentalization is to keep the fire at its starting point and prevent it from spreading to other locations.

A fire damper can be operated using a manual shaft or an electric or pneumatic motor actuator. These are available for explosion-proof installation in Zone 1, Zone 2, and Zone 22.
