Pressure-Relief and Non-Return Dampers
Halton & Flamgard Pressure-Relief and Non-Return Dampers
Pressure dampers are used to control pressure levels in adjacent zones/areas. They are selected and installed to maintain a higher pressure than surrounding areas to prevent the ingress of hazardous gases. They are typically used in escape routes – fire fighting stairwells etc. – to assist in safe escape and to help the authorities deal with the emergency.
Backdraft dampers are used to prevent recirculation of ventilation air. Particularly useful as a low
cost solution to prevent air recirculation through an idle standby fan of a duty and standby ventilation fan configuration.
