Champion Automatic Backwash Filters

The debris laden dirty fluid enters the strainer’s large bottom chamber where the line velocity gets reduced. Flow continues upward passing in a radial manner through the “sealed” screen element.Unwanted materials are trapped on the inside of the filter element screen. The fluid keeps getting filtered and comes out clean through the outlet nozzle. As the filter screen gets loaded with dirt, the differential pressure keep raising.There is hollow full flow backwash arm extending the full length of the filter element. This can rotate and is piped to atmosphere through a backwash valve.
