Pneumatech OWS 53 Oil Water Separator Condensate Manager, 8102046805

Part #: OWS 53

Pneumatech OWS 53 Oil Water Separator Condensate Manager – 8102046805

The condensate generated by oil-injected compressors contains traces of oil. This oil is removed by receiver tanks, dryers, and filtration. Because oil poses an environmental risk, it must be treated before it can be disposed. This is done by separating the oil and water contained in the condensate, thereby preventing polluted wastewater from harming the environment. It’s not just the right thing to do, in many countries it's a legal requirement.

If you are dumping the water from your air compressor onto the ground, outside, or into your sewer system without it first being treated through a condensate management system, you are breaking the law. An OWS 53 condensate manager will help.

Pneumatech's OWS 53 is the choice of decisions makers who will only settle for the most reliable and effect solution in the market. In the first stage of the dual-stage filtration system, the condensate flows through a polypropylene filter which separates out the oil in two steps: first as the condensate passes through it, and second when it fills in the chamber below which traps the oil that rises to the top. In the second stage, the condensate flows through another chamber where activated carbon filters out any remaining oil particles in the condensate.

The OWS 53 is rated to handle up to 53cfm in a mild climate with dryers and filters connected. If you are only tying this into your air compressor receiver tank, this oil water condensate separator is rated for 66cfm. This specific condensate manager is designed for mineral based oils typically shipped with piston/reciprocating air compressors and smaller rotary compressors.

The Pneumatech OWS 53 is the same as Atlas Copco OSC 25 and the Chicago Pneumatic CPP 31 with the only difference being the company logo on the front. The Atlas Copco part number for their OSC25 is 8102046656 and the Chicago Pneumatic internal part number is 8102046894.
