Automatic Self Cleaning / Backwash Filters

Any, functioning, filter gets fouled in the normal operation cycle and the fluid flow needs to be diverted or stopped for maintenance to be carried out. However, continuous operation cycles call, for filtration to be a continuous process with no interruption of flow for cleaning the filter.

For such applications AOF Filters offers automatic filters/strainers that dramatically cut down maintenance and downtime costs. These automatic filters /strainers have cylindrical elements equipped with backwash arm or wiper blade to dislodge surface deposits during the cleaning cycle.

Debris scraped / wiped off the surface is accumulated bottom of the filter where from it is flushed out through drain valve operated manually or automatically.
