First Break Compressed Air Systems
Natural Gas
A natural gas compressor increases the pressure of a gas by reducing its volume. The natural gas enters the cylinder through the intake valves, where it is compressed and forced out through discharge valves. A gas air compressor is one form of natural gas compressor that is used in a wide range of industrial applications where either high pressure or lower volumes of gas are required.
QRNG
Reciprocating Natural Gas Compressor
A reciprocating gas compressor uses crankshaft-driven pistons to provide compression. The thrust is provided by a positive displacement pump that moves the gas through the system and enhances the gas’s pressure and density. Benefits of reciprocating gas compressors include their ability to produce high power and high pressure compressed gas, as well as the absence of an oil carryover problem.
Reciprocating compressors also generally require a lower initial investment than other compressor types.

QRNG Single & Two Stage Natural Gas Compressors
Based on the proven performance of the QR-25, an air compressor with over 80 years of reliable service, but engineered exclusively for natural gas applications, the Quincy QRNG™ is constructed of heavy-duty cast iron for strength and durability. The cylinders are cast with horizontal cooling fins and machined to rigid tolerances. The Quincy QRNG features an advanced-design pressure lubrication system, rebuildable connecting rods and low-lift valves. Optional gas unloaders available.
