Quincy QRDS® Single-Stage, Oil-Less Reciprocating Air Compressors 5-30 HP

Clean, Oil-Less Air and Quincy Dependability

Quincy's QRDS series of single-stage, oil-less reciprocating air compressors with 5 - 30 HP models are built to deliver up to 100 psig pressure with operating speeds in the 855 - 1020 rpm range; they run slower and cooler than competing models. That gives you higher compression efficiency, lower maintenance, and longer service life. Quincy QRDS compressors are based on Teflon industrial technology to minimize friction while operating without using a single drop of oil. They also employ graphite gaskets which are totally asbestos free, so the Quincy QRDS series of compressors complies with EPA health standards.

The Quincy QRDS is designed to be maintenance free for up to three years or 10,000 hours when operated at 100 psig.

Quality features

Standard features, basic compressor
