QUINCY QRD SERIES SINGLE-STAGE, 2-20 HP TWO-STAGE, 5-30 HP OIL-LESS RECIPROCATING COMPRESSORS

CLEAN, OIL-LESS AIR When you need up to 100 psig of clean air for your hospital, laboratory, pharmaceutical, or bulk material application, you need absolutely clean air. Your system won’t tolerate the smallest hint of oil – exactly why we built the Quincy QRDS. With 2-20 hp models built to deliver up to 100 psig, every Quincy QRDS utilizes Teflon™ industrial technology to minimize friction while operating without using a single drop of oil. They also employ graphite gaskets, so the Quincy QRDS series of compressors comply with EPA health standards. QUINCY DEPENDABILITY With years of proven...

QUINCY QRDT, TWO-STAGE • Clean, oil-less air • Quincy dependability • Setting the oil-less standard CLEAN, OIL-LESS AIR When your application requires clean air, “nearly clean” isn’t clean enough. You need absolutely clean air without a hint of oil. To meet that standard, you need a compressor that operates without any oil – not a single drop – exactly why we built the Quincy QRDT. The QRDT will supply the oil-less air that hospitals, laboratories and pharmaceutical applications require. What’s more, the QRDT uses graphite gaskets, so the compressor complies with EPA health standards....
