Circular air damper BID

Wozair manufactures a range of high integrity butterfly isolation damper suitable for use in a wide range of critical ventilation applications. A range of high integrity dampers has been designed to meet the requirements of the nuclear industry, where low case leakage, corrosion resistance and mechanical integrity are of prime importance. Control Mechanism Manual, pneumatic, or electric operation Leakage Rates The isolation damper has been designed to minimise leakage with the blade in the closed position. Extensive testing on 350 diameter Nuclear HEPA filter Isolation Dampers has indicated a mean leakage rate of 0.0001 m³/sec at a differential pressure of 10,500Pa.
