Design Pressure



Contaminants are captured on the outside of the filter element and effectively backwashed into the drain. The filter is backwashed using compressed air which flushes filtered water at high speed from the top of the container, through the filter element and on to the drain. Backwashing is automatic when the pressure drop across the filter increases. Flushing cycle approx. 10 sec. In some cases the pressure filter can be backwashed with clean water.
