1 ROGERSQNW G SeriesRotary Screw Air Compressors40 350 HP186 1521 SCFM40 210 PSIGL ubricant-Injected Single-StageThe Rogers QNW G Series is a state-of-the-art, single-stage, lubricant-injected, Rotary Screw air compressor assembly with Graphic Operator Access your production requirements are critical, you need the rugged QNW G Series Quincy Northwest G Series compressorassemblies represent thebest of lubricant-injected,single-stage, Rotary Screw technology. The Compressors aredesigned, assembled,and tested in ourCentralia, Washingtonplant. Control panels are CSA Assembly Works For YouFlexible ConfigurationAn example of simplicity and reliability, the QNW G Series configuration is alsoflexible. An assembly can be customized to your specifications. Flange mountedair end available through 760 DesignThe open design of the G Series emphasizes function.

2 The assembly is attractiveand easy to inspect and QNW Compressors Achieve The Lowest Energy Use In The Industry24-hour ProductionThe QNW G Series compressor has a rugged design, capable of operating fullyloaded around the Heat ExchangersOversized heat exchangers, standard on all QNW G Series assemblies, result inlower operating temperatures and reduced maintenance SeparationHigh-efficiency, five-stage air/lubricant separation results in less than 2 PPM(W)lubricant carry over into the plant air Series Air EndAxial flow inlet(3 5% efficiency increase)No speed increasing gears(No parasitic losses)Precision rotor design and manufacture (3% efficiency increase)Variable Speed Fan Drive Control (Optional)Available on air-cooled models. Saves energy, reduces noise and prolongsequipment EfficientHigh efficiency rotor design results in maximum air flow using Capacity DisplayAir capacity display is standard on all G Series assemblies.

3 This allowsmeasurement of how much compressed air the plant uses, how much air is lostthrough system leaks, and how much capacity remains to be Series Air Reheater (Optional)Uses waste heat to improve air quality and quantity, improves overall compressorefficiency, and reduces cooling-water consumption by 20%.Typical Rogers QNW G Series CompleteAssembly. (Model QNW-751)2 Inside the QNW G Series3 The assembly offers:Positive LubricationThe G Series uses a positive displacement lubricant pump to assure properlubrication during startup, operation and shutdown. Unloaded brake horsepoweris approximately 15% of full load, the lowest in the Speed RotorsThe male rotor is direct driven and non-geared. It runs at 1800 RPM motorspeed, maximizing efficiency and minimizing wear while performing at a lownoise standard 5 year air end and motor warranty is the best in the BearingsThe triplex tapered roller bearings are designed to ensure longer life.

4 The B-10life is rated at 130,000 hours of operation. This superior three bearingarrangement consistently provides longer life than competitive SealThe G Series primary shaft seal is a triple-lip type design. This design is morereliable than a mechanical CLS46 synthetic compressor lubricant is scientifically formulatedspecifically for Rogers QNW Rotary Screw air Compressors . CLS46 lubricantprovides superior lubricating qualities, assuring long air-end life and less frequentlubricant change flow inlet housingimprovescompressor efficiency by 3 5% overtraditional radial flow designs. This resultsin lower power consumption to accomplishthe closure inlet valveeliminates the needfor a lubricant stop valve and reduces unloaded power motor mountensureslonger coupling life and quieteroperation. Standard through 760 tapered roller bearingsprovide 30 100% longer life thancompetitive rotor designresults in maximum air flow using minimumhorsepower.
