F3400 Metal Screen Filters with Continuous Circulation are the ideal choice for applications without electricity. The F3400 Filter creates a centrifugal movement of the water to keep the screen clean during the irrigation process. The sediments collect in the lower chamber to be purged by the control valve. As a result there is no increase in head loss during operation. The flushing of the collecting chamber is done automatically by a flushing controller during the irrigation process.
The 3400 Metal Screen Filter with Continuous Circulation is used as a primary filter for water containing minimal quantity of suspended particles and from sources with good water pressure.
