Detects oil risks
25 November 2015
Atlas Copco is now offering on-the-spot oil contamination testing to compressed air users in the UK with the launch of its new O-Box indicator system. The company’s sales engineers measure the oil content of an operator’s compressed air network and submit the results in a report within 3min on site.

A disposable impactor capsule is attached close to the point of use in the network without any interruption to the compressor operation. The air sample flows vertically through multiple nozzles on to an engraved glass baffle plate. The 90° re-direction of the air flow separates any oil aerosols present to attach to the engraved recesses in the baffle and provide a visual indication of their magnitude from 0.1 to > mg/m3. If any oil is present, a reading of particulate spot patterns is then compared to scaled images on an instruction sheet for immediate interpretation.
Atlas Copco engineers can carry out O-Box oil checks free of charge for any type of compressor installation.
