Oil-free vacuum pumps

Atlas Copco has had its vacuum pumps checked for traces of oil by TÜV Rheinland in accordance with the ISO 8573-1 standard.

Three different types of oil-free vacuum pumps were measured and certified: the oil-free claw vacuum pump DZS, the oil-free screw vacuum pump DHS VSD+ and the new Atlas Copco innovation of oil-free liquid ring pumps LRP VSD+. As a result, all three pump types meet the strictest quality requirements and have been classified by TÜV as completely oil-free in the best “Class 0”.

The measurements were carried out without an oil removal device at the outlet between the pumps and measurement membrane. The three pump types were certified by TÜV Rheinland that no traces of aerosol oil (concentration below 0.01 mg/m³) could be detected in the exhaust air flow. The vacuum pumps were certified by the testers to be completely harmless to the quality of the ambient air during the process, because oil-induced damage to sensitive applications and products cannot occur.

Completely oil-free vacuum pumps from Atlas Copco are used in a variety of sensitive areas — in food processing and packaging processes, in the production of semiconductors or medicines, and in the paper industry.
