Fermod 2227 Ser Pressure Relief Valve For 75-150 Panel

The walls of a cold room are constantly subject to strains caused by pressure variations, either from inside or outside of the room. It is important to equalise the pressure when necessary otherwise the walls & ceiling are at risk of blowing out or in causing damage or possible injury. A joint venture between CRH Australia & Fermod, The F2227 had been designed and manufactured to withstand Australia's harsh ambient temperatures and metric panel thicknesses. The F2227 Valve makes it possible to balance internal & external pressures through venting. It's mechanically operated valves (one intake and the other exhaust) has two water tight mobile flaps. This means that when not required the cold room is still sealed without precious cold air leaking out of the room and causing machinery to run more often. When pressure builds up the valves open and allow equalisation. The valve is fitted with an 8w heater which runs continuously and prevents the flaps from freezing. It...
