AFC-Series tubular automatic backwash self-cleaning filters

Automatic self-cleaning

The simple design and quick-element access of the AFC-Series Tubular Backwash Filter can significantly reduce the time and effort required to maintain, change elements and reconnect the unit's valves.

The AFC-Series tubular backwash filter is optimal for applications that demand high-pressure operation, up to 1,000 psi and scalable flexibility. Systems are available in single, duo, and multiplex configurations.
