How The ABF Strainers Work
The ABF is a heavy duty strainer with an automatic, self-cleaning feature built-in. The ABF series is designed to achieve filtration from 3500 to 200 micron and is available with inlet and outlet diameters ranging from 8" to 14".

Straining Process
Water flows through the cylindrical strainer element from the inside-out allowing the strainer screen to trap debris on the inner surface. Debris collects on the inner surface of the screen forming a "filter cake".

Self-Cleaning process
The filter cake causes a pressure differential between the inlet and the outlet of the strainer. When this differential reaches the preset value of 7 psi, the self-cleaning process automatically starts. This operation consists of opening an exhaust valve located on the housing lid and starting an electric motor, which turns two stainless steel brushes which sweep the inner surface of the cylindrical screen. The particles trapped on the screen are dislodged by the revolving brushes and flushed out through the open exhaust valve. Service flow of strained water is uninterrupted throughout the approximately 20 second cleaning process.

Control System
The ABF is equipped with a pressure differential switch (PDS) that transmits an electric signal to the control board, initiating the flush cycle. A solenoid operates the exhaust valve by means of a hydraulic command or compressed air.

Features
Flushing can be initiated by the PDS or an adjustable timer setting. A fault indication output can be integrated into an existing central control system (to provide an alarm, open a bypass, shut-off a pump, etc.).
