Pneumatic Water Separator


The "Liquid Super Separator" is a new concept of a pneumatic mist remover without filter element. The "Element Free Pneumatic Water Separator" uses a special centrifugal technique with "radial multi-nozzles" that is world patent pending and makes it possible to reject liquid mist (water and oil) to 99.9%! This pneumatic mist separator is virtually maintenance free, as there is no need to replace any filter element. A standard traditional filter with an element and automatic drain may be placed downstream to control micron size but the high liquid and mist removal of the separator will keep it clean and it may not require element replacement for an extended period of time. Maintains extremely low pressure drop

  • Oil mist rejection rate : 99.99%
  • Semi-permanent durability
  • Power free
  • Complete with Auto-drain
  • No performance change over time
  • Trouble free with simple construction
  • Large capacity but compact
  • Low cost
  • 5 year warranty (except for auto drain)

    How Pneumatic Water Separator Works:

    The Nex Flow™ Super Separator is a unique device designed to near eliminate water and oil removal filter cartridge replacement. The Nex Flow™ Super Separator is designed to be used near the point of use of compressed air and will remove 99.9% oil and water. No filter cartridges need to be replaced. If a standard filter is utilized after the Nex Flow™ Super Separator, the filter cartridges may not need replacement for 4 times or more longer than before saving significantly on downtime and maintenance and in energy loss from system pressure drop.
