OSC 625 oil/water separator combined with activated carbon

Effective and effortless condensate treatment

An oil-water separator removes the oil from your compressor condensate before it can enter the sewage system. However, too many oil-water separators offer subpar quality and minimal ease of use. Atlas Copco’s OSC series allows you to comply with local regulations and to protect the environment with unmatched filtration precision and zero-hassle maintenance.

High purity:

- Dual-stage filtration with polypropylene and activated carbon removes a wider range of oil types.

- Minimal oil content at outlet, as low as 5 ppm if required.

- Test outlet verifies filtration performance.

Easy to use and service:

- Easily removable filter bags and cartridges simplify and shorten maintenance.

- Long service interval of 4,000 hours.

- Service indicator signals the polypropylene filter is saturated.

- Overflow indicator monitors correct water passage.

High efficiency, 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, 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.
