Condensate Management
Oil Water Separators 
Omega Air logo.jpg

Condensate is an unavoidable result of air compression. It is a chemically aggressive fluid that mainly consists of water, but also contains oil and dirt particles.


Oil carryover is unavoidable if you have compressors that use oil in the compression chamber. The lubricant will mix with the condensation and create an oily water that must be properly handled to avoid violating environmental regulations.


Just one litre of used oil can contaminate up to one million litres of fresh water. This is the reason that environmental regulations strictly prohibit the discharge of oily wastes and chemicals, including the condensate drained from a compressed air system.


Compressed air condensate must therefore be treated in accordance with water resource legislation to achieve prescribed safety levels before it can be disposed of in the waste water system. Compressor condensate must therefore be either collected and treated by special processes or treated prior to disposal to the environment. An oil/water separator can be used here to remove the oil from the condensate. Since the condensate is approximately 95% water and 5% oil, water/oil separators have been developed to reduce or eliminate the amount of oil in the condensate.

WOS Oil Water Separator <Click here for sizing table>

WOS water oil separators have been developed to separate lubricant oil from

condensate from compressed air systems.


WOS water-oil separator can be

used in variety of applications.


For applications not listed please contact us 

WOSm Oil Water Separator <Click here for sizing table>

WOSm water oil separators have been developed to separate lubricant oil

from condensate generated in compressed air systems.


Due to patented technology regular service can be done in 30 seconds

without any cleaning. Separation begins in “cyclonic depressurisation chamber”

and continues in “filter cartridge”.


When the “filter cartridge” is fully saturated you just

simply unscrew complete cartridge and replace it with

new one.


All the condensate stays in old cartridge

which can also be sealed with plastic cover and

disposed according to local

directives and laws.

WOS CD Oil Water Separator <Click here for sizing table>

WOS CD is intended for systems, where amount of generated condensate

exceeds capacity of single largest available WOS water oil separator.


WOS CD can evenly distribute collected condensate between up to three WOS 35

water oil separators. WOS CD is equipped with flow distributor

on the inlet port, up to 8 hose tail connections mounted on elbows

for convenient outlet, manual ball valve for cleaning purpose and vent port for safe aeration.


Optional wall mounting kit is available. Maximum capacity in regard to free air delivery,

when connected to WOS-35 is 120 Nm3/min.
