G Series
Rogers QNW G Series is a state-of-the-art, single-stage, lubricant-injected, rotary screw air compressor assembly with the Graphic Operator Access Terminal(GOAT). The GOAT is a microprocessor control designed to monitor, regulate and protect the compressor. Sensors continuously transmit temperature and pressure information to the processor. This data allows the most efficient compressor operation, annunciation of proper service intervals and alarms, and initiates shut down due to abnormal operating conditions. See Brochure

Inside the G Series
![]() |
The G Series compressor assembly represents the best of oil-flooded, single-stage, rotary screw technology. All components are manufactured in the U.S.A. The compressors are assembled in our Centralia, Washington plant. Standard assemblies are CSA listed. |
G Series air-end is the heart of the compressor's reliability.
| Triplex bearings The triplex tapered roller bearings are designed to ensure longer life. This superior three bearing arrangement consistently provides longer life than competitive machines. |
Positive lubrication The G Series uses a positive displacement lubricant pump to assure proper lubrication during startup, operation and shutdown. Unloaded BHP is approximately 15% of full load, the lowest in the industry. |
| Shaft seal The G Series primary shaft seal is a triple-lip type design. This design is more reliable than a mechanical seal. |
Slow speed rotors The G Series' male rotor is direct driven and non-geared. It runs at 1800 RPM motor speed, maximizing efficiency and minimizing wear while performing at a low noise level. |
