Automatic self-cleaning filter AS325-FD

Automatic self-cleaning filter for viscous media and very demanding applications

The AS325-FD automatic filter consists of the following components:

  • filter element
  • sieve (wedge wire element)
  • wiper blade
  • rotating arm
  • motor with spur gearbox

The filter media enters through the bottom inlet flange on the outside of the filter screen. From here it is pushed inwards through the screen, thus filtering it. The cleaned medium then flows into the upper part of the filter and then exits through the upper outlet flange. The solid particles are collected on the outside of the screen where they are continuously removed by a rotating wiper blade. The trapped sludge falls into the lower part of the filter body where it is discharged at regular intervals through the waste valve.

Sludge discharge can be achieved in three different ways

  • manually
  • automatically by timing
  • automatically according to DP

Maintenance is very simple, by loosening the 6 screws and hinging the lid with the motor, the wedge-sieve can be removed, which can then be cleaned of dirt.
