Atlas Copco introduces compact oil-water separator for GX range of workshop compressors

April 14, 2016

Atlas Copco has launched a compact and lightweight oil-water separator unit for its GX 2-7kW range of workshop compressors, employing advanced absorption materials to help safely dispose of oil in compressor condensate.

Compact and lightweight OSS oil-water ceparator

The condensate generated by oil-injected compressors, after-coolers, dryers, vessels and filters contains traces of oil, dust and moisture and must be treated to eliminate any risk to the environment − and comply with stringent environmental regulations − before it can be allowed to enter the sewage system.

With its new OSS oil-water separator, Atlas Copco provides a compact, clean and cost-effective answer for small compressor installations. Smaller than a shoebox, measuring just 240 mm x 140 mm, and weighing approximately 1 kg, the unit has been designed to operate with Atlas Copco’s state-of-the-art GX workshop compressors.

Quick and easy to install, and constructed with 100% recyclable materials, the small OSS unit operates on a two-stage principle. Firstly, condensate enters a depressurisation chamber and undergoes pre-filtration whereby polypropylene material captures large oil droplets. In the second stage, small oil droplets are efficiently absorbed by recycled glass material. After separation, the discharge water contains oil levels below 15 parts per million (PPM), and an optional easy sampling kit is available to verify outlet concentration on a regular basis.

Until the end of May 2016, the new OSS oil-water separator is on offer free of charge with a GX compressor when purchased through Atlas Copco’s e-commerce website The Compressor Store. The website provides small manufacturing companies, garages and workshops, with an easy and competitive way to compare prices, product descriptions, technical specifications and reviews to identify the compressor solution that best suits their needs.
