A filter removes dirt from the water and prevents the water system from clogging and damaging the water system. Filters can release water from both rough and very dirty pollution of about 50 microns. Each filter has its own dirt capabilities, maximum flow rates and cleaning methods.

The filter range is divided into 4 different filters:

  • Plastic filters, all filters with a plastic/plastic outer shell;
  • Media filters and filters that filter with a certain amount of sand, gravel or other media;
  • Metal screen filters, filters with a steel exterior that can be completely both automatic cleaning and manually cleaning, and;
  • Special filters, these filters are special concerning operation or applications.

There are three different cleaning methods of filters: manual, semi-automatic and automatic.


Manual filters are filters that can clean only by hand. That is to say, remove the inner filter from the house, clean the rinse/brush, after which the filter can be placed back in the house and will be useful again. Manual filters are usually used for water with very little fouling.


A semi-automatic filter can be manually cleaned without opening the filter housing and without interrupting the system. The filter is cleaned by internal nozzles, which can be manually operated by a pendulum. These nozzles clean the filter and rinse the contamination through a purge tap.


An automatic filter is automatically operated and cleaned. The filter is also cleaned by nozzles operated by a hydraulic piston or electric motor. The nozzles rinse the contamination through a rinse crane. The automation of automatic filters can be supplied by us in a Filtron or other specific controller.
