PRD Pressure Relief Dampers

by Waterloo Air Products plc

The Waterloo PRD pressure regulating dampers are designed to maintain a preset constant pressure differential across a partition wall or within a duct system. The damper incorporates a finely balanced aerofoil blade which is capable of regulating room or duct pressures within a tolerance band of ± 3 Pa over a wide airflow range.
Control pressures are factory set to customer requirements but may be adjusted in service by changing the blade weights. The units are available in three standard widths, with modular heights up to 1275mm, and may be combined with grilles or louvres for through the wall installations.
Typical applications include operating theatres, laboratories, or clean rooms where cascade systems may be used to regulate room pressures. They are also suitable for zone pressurisation systems for smoke control in the event of fire.
