Ultra-fine filters / Pressure filters

Ultra-fine filters FFR

The POLO Fine Filter FFR is a closed in-line filter system for the fully automatic cleaning of a wide variety of liquids.
The special feature is the backwash filter inserts. The ultra-fine filter can filter up to 3 μm particles despite different volume flows.
Special filter inserts even manage up to 1 μm.

Their advantages

  • Space-saving
  • Low energy consumption
  • Low maintenance

Short info

  • Variable filter finenesses
  • Easy replacement of the filter inserts
  • Backflash option
  • Low costs for consumables

Various filter inserts

By selecting the filter inserts, a wide variety of finenesses can be achieved. Each filter insert can be backwashed and therefore has a long service life.

Due to its compact design, the system can be easily retrofitted to existing systems / machines.



The ultra-fine filter consists of a pressure vessel with two filter inserts. The filter inserts can be backwashed.
Backwashing of the filter inserts is differential pressure or time-controlled. The backwash volume is processed by a secondary filter system.



The ultra-fine filter is mounted on a two-chamber tank which consists of a dirty and clean side. The dirty medium is transferred to the dirty chamber. By means of a filter circuit pump, the medium is forced through the ultra-fine filter and enters the clean chamber. The backwash process is triggered depending on the differential pressure. The backwash is carried out with purified medium. The backwash material is passed on to a secondary filter system.
