About Atlas Copco
Atlas Copco is a Swedish industrial group founded in 1873 in Stockholm and headquartered in Nacka, just outside the city. Its business areas are Compressor, Vacuum, Industrial and Power Technique.
The G series is Atlas Copco’s line of fixed-speed, oil-injected rotary screw compressors. CompressorPros offers tank-mount G models from 3 on up, a size range that fits shops moving up from a piston unit or adding a machine that can run all day.
Atlas Copco G Series Rotary Screw Compressors at CompressorPros
G2 and G4 Tank-Mount Packages
The G2 and G4 are 3 HP and 5.5 HP packages, and the Pack versions sit on 53 gallon horizontal tanks. They come for 230V single-phase or 208-230/460V three-phase supply and use the Elektronikon Nano controller. The G2-116T AP delivers 12.7 CFM at 116 PSI, and the G4-145T AP 230/1 delivers 16.7 CFM at 116 PSI.
G11 for Larger Shops
The G11 is a 15 HP three-phase unit on a 120 gallon horizontal tank, rated at 52.8 CFM at 125 PSI with a 129 PSI maximum. It suits shops running several air tools or production equipment at once.
Full Feature Packages With a Built-In Dryer
Atlas Copco’s Full Feature versions add an integrated refrigerant dryer, so dry air leaves the package without a separate dryer. The G2-145T AFF brings this to a 3 HP single-phase unit, and the G11-125 FF does the same at 15 HP. Compare other air compressors with dryers for more sizes.
Choosing an Atlas Copco G Series Compressor for Your Shop
Power supply. The G2-145 and G4-145 come in 230V single-phase, which is less common among rotary screw compressors. The G2-116 and G11 are three-phase only. Have a licensed electrician confirm your service and circuit before you order.
Air at working pressure. Add up the CFM of the tools you run at the same time, at their working pressure, and leave room for leaks and growth. The range runs from 9.9 CFM at 145 PSI on the G2-145 to 52.8 CFM at 125 PSI on the G11.
Pressure versus flow. Within the G2 models, a lower pressure rating gives more air: 12.7 CFM at 116 PSI versus 9.9 CFM at 145 PSI. If your tools run at about 90 PSI, the lower-pressure model typically gives you more usable air.
Noise and duty. The G models are rated at 61 to 67 dBA, quiet enough in most shops to sit near the work area. All of them are rated for 100 percent duty, so they can run continuously through a full shift.
Atlas Copco Parts and Maintenance
Rotary screw compressors need regular oil, oil filter, air filter and air/oil separator changes. Follow the service intervals in your Atlas Copco manual and use the parts and fluids it specifies, which supports performance and may matter for warranty coverage.
CompressorPros offers individual Atlas Copco parts such as intake valves, belt sets, safety valves, sensors and control kits. Match the part number to your machine before ordering, and browse filters, oil and maintenance kits for other service items.
