Oil & Water Extractors

Reliable and Efficient
All compressed air systems contain water, dirt, rust and even degraded lubricating oil which all mix together to form unwanted compressed air condensate. This abrasive sludge collects in piping systems, filters,

aftercoolers and dryers and must be efficiently removed before it brings your production process to an expensive standstill.

Efficient on-site disposal of compressed air condensate with CompAir CS Range Oil/Water Separators.

After the oily condensate has been removed from the compressed air system, it cannot be discharged without the oil content being reduced to legal disposal limits.


The simple, economical and environmental solution is a CompAir CS Range Oil/Water Separator.

Oil/water separators are installed as part of the compressed air system and simply reduce the oil concentration in the collected condensate. By reducing the oil concentration in water to a permitted level, this allows the larger volume of clean water, up to 99.9% of the total condensate, to be discharged safely into the environment. This leaves the relatively small amount of concentrated oil to be disposed of legitimately and economically.

User Benefits

  • Help to protect and maintain the environment
  • Efficiently separate oil and water on-site and dispose up to 99.9% of the condensate
  • Meet trade effluent discharge regulations
  • Rapid payback over conventional disposal methods
  • Simple to install, operate and maintain

Standard Features

  • Large single piece units
  • Robust rotationally molded polyethylene construction
  • Ribs included for extra strength
  • Large centrifugal inlet chamber for effective venting of compressed air energy
  • Centrifugal inlet chamber has two inlet ports and four positions for ease of installation
  • Large, easily cleaned primary settlement chamber for the accumulation and removal of dirt particles
  • Large main settlement tank for increased settlement time and reduced oil carry-over to carbon stage
  • Large internal galleries reduce risk of internal blockage
  • Pre-filter for carbon bag protection
  • Large, carbon stage for increased contact time, improving water quality and extending carbon life
  • High specification carbon for improved service intervals
  • Optional flashing overflow indicator, or remote alarm contacts available
  • Adjustable oil outlet funnel for efficient removal of separate oil
  • Sealed external oil container for easy disposal
  • Sample tap for easy testing of outlet water quality

Standard Features

  • Remote overflow alarm connection (CSOA)
  • Overflow indicator (CSOI)
  • Flow splitter available on request

Clean and Simple Operation
CompAir
oil/water separators are designed to separate compressor oil from condensate without the use of external power. The oil/water condensate should be removed from compressed air system using a drainage method appropriate for the unit.

  1. Condensate from the system will enter the oil/water separator under pressure and is allowed to expand in the specially designed centrifugal inlet chamber.
  2. Liquid will drop out of the air stream as it impinges on the chamber walls and the vortex generator, draining without turbulence into the primary settlement chamber below.
  3. Dirt particles suspended in the condensate will settle to the bottom of the primary settlement chamber and the accumulating condensate will then flow into the main settlement tank.
  4. Entrained droplets of oil dispersed in water will rise to the surface due to the lower gravity of the oil, eventually coalescing to form a thick layer on the surface.
  5. Clean water taken from the bottom of the tank, flows into the carbon stage, through a pre-filter, into the top of the carbon bags.
  6. Any entrained droplets of oil remaining are then removed by absorption.
  7. The cleaned water can now be safely discharged through the outlet

Selection Criteria and Product Selection

Important Note:
Additives blended into the lubricants to prevent bacterial growth, rusting, corrosion and to promote emulsification, such as detergents etc., can have an impact on the separating process. Static oil/water separators are unable to separate stable emulsions or oils that are miscible in water. Additionally, these units will not completely separate stable lubricants containing: emulsifying agents; glycol additives; or polyglycol based coolants.
