OSC 85 oil/water separator combined with activated carbon

Atlas Copco’s OSC 85 offers adsorption-based condensate management for oil-injected compressors.

If the oil in the compressor condensate is not removed before it enters the wastewater system, it can cause significant environmental damage.

Therefore, condensate treatment is not only the responsible thing to do; in most countries, it’s the law. Thanks to its multi-stage filtration, Atlas Copco’s OSC removes oil from your compressor’s condensate with unmatched precision to achieve an oil content of 10 ppm at outlet.

The Atlas Copco OSC oil-water separator uses proven, reliable and robust technology to remove oil concentrations to a maximum of 10 ppm.

Highly efficient multi-stage filtration:

1. The condensate enters the unit via one single or multiple inlets. It passes through a diffuser and depressurizes in the expansion chamber. The diffuser removes bigger solid particles from the condensate so that these cannot compromise the filter media.

2. The oil-water mixture continues to the first filter chamber. It seeps through the polypropylene filter, which adsorbs the oil, but not the water.

3. The condensate remains in the chamber for a while, starting a secondary, natural filtration as the remaining free oil floats to the top and is adsorbed by the filter bag.

4. Significantly cleaner condensate flows into the second chamber.

5. A removable cartridge, filled with activated carbon (or organoclay for stronger emulsions), separates the remaining oil droplets from the condensate.

6. Clean condensate exits from the removable cartridge with almost no residual oil content, allowing for safe discharge into the sewer system.
