GCOS Series Oil / Water Condensate Separator

The GCOS system was developed to effectively separate the oil out of condensate that forms from a compressed air system by using a poly-element type filter. Different types of poly-elements with proprietary chemicals are available to treat ATF, Poly-glycol coolant and silicones.

A carbon filter is also utilized to remove any final traces of oil down to 10 PPM, then condensate is treated and the clean condensate is drained. The filter life is directly linked to how much oil exists in the system, more oil means more frequent filter changes.

Air compressors can produce considerable amounts of oil-contaminated condensate. The oil can’t be discharged directly into open drains, public sewers or natural watercourses.
