Innovative dual gradient design allows creating two distinct filter zones.


Larger particles are trapped and filtered out in the first zone and the smaller particles are trapped in the second zone.


It allows the cartridge to operate at higher velocities and lower pressure drop.

This structure allows filter efficient water purification with higher filtration rate with lower pressure drop.


The filter is intended to purify water from sediment particles such as rust, sand, scale, silt etc.


Key advantages

  • Up to 300,000 liters capacity

  • 25% higher rejection rates comparing to standard PP filters

  • Low pressure drop
