The SAF filter series are sophisticated yet easy to operate automatic filters, with a self cleaning mechanism driven by an electric motor. The SAF is designed to work with various types of screens and is available in 4″, 6″, 8″, 10″ inlet/outlet diameter.

  • For high flow rates -up to 400 m³/h; 1760 USgpm
  • Large filter area -3,000, 4,500 and 6,000 cm²
    xxx in², 690 in², 930 in²
  • Minimum water waste during flushing -less than 1%
  • Filtration degrees -from 500 to 10 micron
  • Uninterrupted downstream flow while flushing -self cleaning based on pressure differential and/or time option for continuos flushing.
  • Wide range of applications -water supply, cooling water, process water, effluent water.
  • Flexibility of construction materials -for adapting the units to different types of water and liquids.
  • Cooling water in high buildings and  industry.
  • Polishing effluent water in paper mills.
  • Filtration for drip irrigation.
  • Municipal drinking water supply.
  • Supply water for various industries.
  • Elimination of Zebra mussels.
  • Golf courses irrigation.
  • Pre filtration for ultra filtration and reverse osmosis.
  • Sea water filtration
