Class O is TÜV-tested

TÜV is an independent, international organization specializing in evaluating the safety and quality of technologies. The TÜV is recognized worldwide for its independence, neutrality, professional expertise and strict standards. Our oil-free air compressors underwent the most severe tests available.

All possible oil forms were measured across a range of temperatures and pressures but, because no traces of oil were found in the output air stream, our compressors surpassed TÜV’s stringent standards.
