The Waterloo back pressure dampers, series BPD, may be used for room-to-room pressure control or as basic non return valves. Units are suitable for partition, wall, plenum, or duct mounting for projects requiring coarse control of differential pressure. The damper blades modulate automatically with increasing pressure and produce a flat pressure response which is useful for regulation purposes.
All dampers are constructed from aluminium alloy extrusions with mitred and welded/cleated frames. The blades are supported on plastic moulded bearing surfaces and blade weights are provided to vary control pressure.
