Isolation and Retention Dampers
Halton & Flamgard Isolation and Retention Dampers for Demanding Applications
High integrity gas retention dampers are used for containing fire-extinguishing gases such as CO2 and FM200 within a ventilation or air-conditioning system during fire situations. They have a similar design to volume control dampers with additional seals to minimise leakage.
When actuated – electrical, pneumatic or hydraulic – gas retention dampers prevent movement of gases which are deployed to evacuate oxygen and effectively extinguish the fire, this assists the building systems – alarms, sprinklers etc. – and the fire authorities to ensure safe escape and to minimise fire damage.
