A byproduct of air compression is condensate. Condensate usually collects and should be drained from after-coolers, filters, tanks, and dryers is usually contaminated with compressor lubricant. Oil-water separators separate and clean waste liquid from the compressed air system so that the condensate may be safely and legally (EPA and Local) discharged into most sewer systems. We offer OWS's from Jorc, Clean Resources and Chicago Pneumatic.
