(Capacity is based on the compressor running at 7 barg/100 psig or 12 hours per day, with all condensate from the compressor, the air receiver, the filters and refrigerant dryer piped into the unit. All capacities are based on an outlet oil content of 10 mg/l)


Oil water separators are a legal requirement, not an option, in most instances. Trace amounts of oil can be found in the condensate from oil injected air compressors.

The multi-stage filtration used by an Atlas Copco OSC removes oil from your condensate down to a level of 10 ppm at outlet – delivering unmatched precision, as you would expect from Atlas Copco.

Maintenance of this part is simple due to the easily removable filter bags and cartridges.

Condensate treatment is compulsory and regulated under the Water Resources Act (1991): law of discharge in the UK, Hazardous Waste regulations Act (2005) and European standard applicable since 23/10/2000. In the UK, a site must have a consent to discharge from the local water authority. Generally, the limit is 20ppm, but you need to check with your local authority as regulations can differ between areas.
