LPG Fire Australia stocks a wide range of Puma fire rated barometric pressure relief vents for both inert gas and synthetic gas fire suppression systems.

Dual Flow Pressure Relief Dampers


The Dual Flow damper Inner Fire Section is fitted with balanced weighted blades, hinged on stainless steel rods and bronze bearings. The precision engineering and blade overlap provides a positive shutter to the wall opening and minimum leakage.


All Dual Flow Dampers are fitted with integral ‘ Cat Flap ‘ or positive shutoff closing door, this is held in place with a magnetic catch – this provides an intrinsic sound barrier and a positive air, dust and noise seal.


The integral ‘ Cat Flap ‘ will Provide a natural thermal barrier between the two areas, ideal when fitted in external walls, this will help to prevent condensation forming on the Inner Fire Section blades. Additional insulation can be fitted to increase the thermal and sound absorption characteristics


All products are manufactured from Zintec Steel and polyester powder coated to RAL9010

Special colours are available on request
