Atlas Copco OSC25 Oil Water Seperator

Efficient. Compliant. Maintenance-Free.

When it comes to operating an oil-lubricated air compressor system, handling condensate responsibly isn’t just best practice—it’s the law. The Atlas Copco OSC 25 oil-water separator offers a compact, cost-effective, and eco-conscious solution that ensures you stay compliant with environmental regulations while protecting your compressed air system.

Why the OSC 25?

Compressed air systems naturally generate oil-laden condensate—a mixture of moisture and trace oils that, if improperly disposed of, can lead to heavy fines and environmental damage. The OSC 25 removes virtually all oil from compressor condensate, allowing for safe, legal water discharge directly into the sewer system in accordance with local environmental standards.

Key Features & Benefits

• No Electricity Required – The OSC 25 operates entirely mechanically, which makes it ideal for remote sites or energy-conscious facilities. No power supply or control panels needed—just set it up and let it work.
• Multi-Stage Filtration Process –  Utilizes a dual-stage filtration system including polypropylene and activated carbon filters that separate oil down to a residual level of <10 ppm, depending on the conditions.
• Universal Compatibility –  Designed for use with all types of lubricants, including mineral, synthetic, and ester-based oils—making it a versatile solution regardless of your compressor brand or model.
• Long Service Life – Built with robust materials that offer resistance to pressure, temperature, and corrosion. Internal media offers extended operational cycles, minimizing the need for frequent servicing.
• Tool-Free Maintenance –  Easy-to-access filter cartridges allow for quick, no-tool replacements. Visual indicators notify operators when filters are saturated.
• Compact & Space-Saving – Its vertical, free-standing design allows you to integrate it neatly beside your compressor without eating up floor space.
