FlexiFilter 400


The FlexiFilter filter material is suitable as a replacement for common filter cartridges for sand and cartridge filters. The FlexiFilter 400 package contains round filters of ø40 cm (4.5 cm thick).

  • When used alone, it is possible to stack several round filters on top of each other in the filter housing.
  • A “FlexiFilter 50” filter cartridge is recommended as an accessory part of the filter. It is designed for a deep filtration of liquids. The round filter ensures the overall efficiency of the filtration, the “FlexiFilter 50” cartridge ensures the volume capacity of your filtration.
    If you combine the cartridge with FlexiFilter 50 cubes, insert the round filter as the last layer. Never fill the filter housing completely.

FlexiFilter is a highly efficient filter for industrial and domestic use. FlexiFilter is a filter material with an excellent efficiency. It has a higher filtration capacity compared to traditional sand, cartridge, and other filters. Thanks to a deep filtration, it absorbs a larger number of impurities. The material is lightweight for easy handling. FlexiFilter works with a very low pressure drop.

The right size choice

In the pool skimmer, the round cartouche of the pre-filter is inserted either into the space of the housing (the diameter marked in red in the photo) or into the deep sieve basket (the dimension marked in yellow in the photo). Please make sure that the material does not interfere when opening the skimmer door. Always choose a slightly larger pre-filter diameter than the measured dimension.

Benefits of FlexiFilter:

  • Trapping of impurities of up to 0.003mm.
  • Easy handling and replacement.
  • A low pressure drop = energy savings
  • High absorption of impurities by a depth filtration.
