A specially designed circulation plate, installed at the top of the screen, filters the water through four directional holes into the filter in a descending circular pattern.

This continuous downward spiral flushes the screen and forces the debris to the collection cell. The collection cell can be drained during the filtration process manually, automatically or continuously by a bleeder.

Pictured here is a Manual Circulating Screen Filter. Netafim offers an optional flush valve and timer.
