Fire & Smoke Damper

The Holyoake HFS damper is a fire, fire-smoke, and smoke rated motorised steel damper, designed to impede the spread of fire through ducted air systems whilst maintaining barrier integrity. Self-contained as a fire damper and externally operable by a spring return actuator, the HFS damper offers supreme fire and smoke leakage performance due to the unique patented sealing system.
