Oil-water separators are designed to separate lubricants from water to comply with state environmental protection laws and regulations.

In an air compression environment, condensate is a by-product derived from the cooling and dehydration process that compressed air generates and how it’s treated. Some types of air compressors use a small amount of lubrication in their system, which can enter into the air stream. This water/lubricant mixture produces and oily water mixture and must be treated before it can be disposed. Most states now consider air compressor condensate as a hazardous waste, so companies face tough new standards they must follow or they will be subject to stiff penalties for non-compliance. Proper separation equipment is necessary to keeping with state environmental laws and regulations.

The key to the PolySep Oil Water Separators’ unrivaled performance is our unique, specially coated Zeolite absorption media. This proprietary filtration media effectively separates and permanently absorbs virtually all lubricants, including highly emulsified lubricants like polyglycols, the most difficult lubricants to separate. Competitive systems simply can’t handle polyglycols without requiring expensive, oversized separators. From mineral oils, PAOs and polyolesters to diesters and polygycols, the PolySep Oil Water Separator provides the broadest range of performance and efficiency.
