(1) ea. Atlas Copco GA5-11 Oil-Injected Rotary Screw Air Compressor.


Key Features & Technical Specs

Here are some of the standout features and typical specifications:

Motor power / capacity range: The GA5-11 covers approximately 5.5 kW to 11 kW (≈ 7.5-15 HP) motor sizes.
Operating pressure / free air delivery: One spec sheet lists ranges like 107-181 psi max, 24.7-64.1 CFM for the unit.
Ambient conditions: Designed to operate in ambient temperatures up to 46 °C.
Energy efficiency: Combines an IE3 efficiency motor, an optimized screw element, improved bearings/seals — all to reduce energy consumption. According to Atlas Copco, compressor generation of air can account for over 40% of a plant’s total electricity bill, and thus the GA is built to minimize that life-cycle cost.
Oil vessel / carry-over control: The vertical oil-vessel design helps achieve very low oil carry-over into the compressed air, and low losses during unload.
Plug-and-play installation: The unit is offered in base-mount and tank-mount configurations; there are options for integrated dryer and tank. One spec sheet says “ready to be installed close to the point of use” and includes standard features like a 3 m power supply cable.
Air treatment integration: Optional integrated dryer, filters, and tank mounting are available to deliver “quality air” — e.g., filters to reach air-quality class 1 (<0.01 ppm oil) downstream.
Standards & reliability: The GA series is designed, manufactured and tested in accordance with ISO 9001, ISO 14001 and ISO 1217 (Ed.4 Annex C/E) standards.
