Quiet Air Compressors

The “original” quiet compressor with a noise level below 45 dB(A). The Jun-Air oil-lubricated compressor is the lifeline of dental surgeries worldwide, and many units are still in operation after 25 years – a testament to the quality and reliability of Jun-Air compressors.

JUN-AIR oil-lubricated piston compressors are — contrary to traditional compressors — not supplied with piston rings. Instead the tolerance between the piston and the cylinder has been reduced, minimizing the heat development and the energy loss.
