Cleaning principle of the automatic filter
4
A cleaning cycle is started when the maximum differential
pressure is reached (if a pressure transmitter / optional
differential pressure switch is installed) or after a preset
time.
5
The gear motor begins to turn the inser.
6
The valves (6+7) open. The flush medium flows at high
velocity from the external nozzle (8) through the filter wire
cloth and into the internal nozzle (9). The dirt particles are
thus discharged via the flush valve (6). The flush valves are
closed after one rotation. The filtration process is not
interrupted.
