Atlas Copco GA5 - GA11 Oil-Injected Rotary Screw Air Compressor

 Atlas Copco GA 5–11 is a premium oil-injected rotary screw compressor line engineered for reliability, efficiency, and point-of-use installation. Built and tested to ISO 9001 / ISO 14001 and performance verified to ISO 1217 (Ed.4, Annex C/E), the GA 5–11 delivers clean, dependable compressed air while minimizing total lifecycle cost. The WorkPlace Air System design runs quietly and integrates air treatment and tank-mounting, so you don’t need a separate compressor room—just set it where you use air and go.

Why it’s better

• IE3-efficiency motor mated to Atlas Copco’s time-proven screw element and optimized packaging: up to +8% Free Air Delivery and –7% power use vs prior designs.
• High-tech vertical oil vessel: ultra-low oil carryover and minimal losses during load/unload.
• Optimized belt drive train for long, trouble-free service—even in ambient temperatures up to 46 °C.
• Plug-and-play: forklift-friendly, 3-meter power cable, easy service access, and long-life consumables.

Smart control & energy savings (Elektronikon®)

• Web-based online status visualization via Ethernet, with warnings, shutdowns, and maintenance scheduling.
• Dual pressure set-point and Delayed Second Stop (DSS) reduce off-load energy waste.
• Linked Saver Cycle trims fan and dryer energy based on oil temperature and ambient conditions; auto-restart after voltage failure; upgradeable to graphic controller and to integrated ES control (up to 4 or 6 compressors).

Quality air, lower footprint

• Integrated refrigerant dryer with no-loss condensate drain, water separator, low pressure drop heat exchanger, and R134a refrigerant.
• Typical 30% energy savings with the new integrated dryer range; ~50% lower GWP by reducing refrigerant charge.
• +3 °C PDP (at 20 °C, 100% RH). Optional filters to Class 1 air quality (0.01 ppm oil).
