How it works

 

GENERAL

The TAF series consists of easy to operate 2″ and 3″ self-cleaning plastic filters, made of high quality material and driven by an electronic self-cleaning mechanism. The different types of TAF filter screens are designed for applications requiring filtration fineness of 500-10 microns and flow rates up to 50 m³/h (220 gpm).

 

THE FILTRATION PROCESS

Water enters the inner area of the filter (1) through the inlet (2) and flows through the screen to the filter outlet (3). The dirt particles accumulate on the inside of the filter screen and form a “filter cake” which causes a pressure differential.

 

THE SELF-CLEANING PROCESS

During the self-cleaning process, while filtered water continues to flow, the filter flush valve (4) is opened and the drive unit (5) actuates the dirt collector (6). The spiral rotation of the dirt collector with suction nozzles moves over the inner surface of the screen and sucks the filter cake out through the flush valve.

 

THE CONTROL SYSTEM

The control system consists of an Electronic Flushing Controller (7), a 3-way solenoid valve (8) that operates the filter flushing valve and
a differential pressure switch (9) that measures the differential pressure across the filter screen and sends a signal to the controller when it reaches a preset value (usually 0.5 bar / 7 psi).

The controller begins a self-cleaning cycle under one of the following conditions:

1. On receiving a signal from the differential pressure switch
2. Upon reaching a time interval parameter set by the user
3. Manual start function on the controller keypad.
