UL listed Fire Damper

Motorised (electric, pneumatic / Manual operation, leakage Class I, high temperature, high pressure, UL listed fire dampers, also for explosion proof hazardous area 

Fire Dampers 

High Performance, low leakage, robust, high temperature fire dampers are used in air transfer openings, wall opening, ducts, and 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. 

Fire dampers can be operated using manual shaft, or electric / pneumatic motor actuator. These are available for explosion proof area Zone 1, Zone 2, 22 installation.
