① Maintenance-Free Drive System
Maintenance-free and fully enclosed design prevents dust, dirt, and other contaminants from entering the drive system.
High-efficiency gear drive eliminates the efficiency losses associated with couplings, ensuring reliable power transmission.
Standard models can operate at ambient temperatures up to 46°C, while high-temperature models can operate reliably at up to 55°C.

② High-Efficiency Motor
IE4 motor efficiency class (with continuous efficiency improvements).
IP55 protection rating, Class F insulation, with Class B temperature rise for enhanced reliability.
Grease-lubricated, maintenance-free bearings on the non-drive end reduce maintenance requirements.
Designed for continuous operation in harsh environments, delivering reliable and stable performance under demanding industrial conditions.

③ Robust Spin-On Oil Filter
High-efficiency filtration removes contaminants from the oil, helping extend component service life and maintain reliable compressor performance.
Oil filter with an integrated bypass valve ensures reliable oil circulation and protection during demanding operating conditions.

④ Independent, Oversized Oil Cooler and Aftercooler
Large, independent oil cooler and aftercooler design provides efficient heat dissipation and reliable cooling performance.
Low rotor outlet temperature helps extend oil service life and maintain stable compressor performance.
Built-in mechanical water separator removes nearly 100% of condensate, delivering cleaner and drier compressed air.
Stress-relieved design minimizes thermal stress and eliminates thermal shock in the heat exchangers, enhancing durability and reliability.

⑤ Intelligent Thermostatic Valve (GA 55+ / GA 75+)
Maintenance-free design
Controls the cooling oil flow to maintain the optimal oil injection temperature for efficient and reliable compressor operation.

⑥ Smart Sensors (GA 55+ / GA 75+)
Differential pressure sensors monitor the service life of the air intake filter and oil separator element, helping optimize maintenance intervals.
SPM vibration sensors monitor drive system vibrations and can send real-time vibration data updates through SMARTLINK (optional).
CAN connectivity makes it easy to expand the system with additional sensors for enhanced monitoring and diagnostics.

⑦ Elektronikon® Touchscreen Controller
Remote control, alarm outputs, maintenance scheduling, and online diagnostics provide comprehensive compressor monitoring and management.
Built-in SMARTLINK remote diagnostics helps maximize compressor system performance, improve energy efficiency, and optimize maintenance.
Multi-compressor monitoring and diagnostics are available, with optional centralized control for 2, 4, or 6 compressors.

⑧ Heavy-Duty Air Intake Filter
Removes up to 99.9% of coarse dust particles, providing enhanced protection for critical compressor components.
Extra-long service life reduces maintenance requirements and helps ensure reliable compressor operation.

Available Options

Equalizer 4.0: Manage up to 6 compressors in one air network with the Equalizer 4.0 (integrated in your compressor or as a standalone unit):
Reduced pressure band: Create a narrow, predefined pressure band to save energy.
Optimal system performance: Program all compressors to have equal running hours to reduce service intervals.
Improve reliability and efficiency: With actionable performance reports, service warnings, and energy efficiency data.
Standard multiple compressor control: VSDS units come as standard with a built-in EQ2i, allowing the control of a second compressor.

OPC UA enabled

Atlas Copco was the first compressor manufacturer to offer OPC UA, the machine-to-machine communication protocol that was developed especially for industrial automation. That means you can integrate your Atlas Copco compressor seamlessly in your production network.

Standardization of production equipment communication.
Insight into production system performance and optimization options on your production floor.
Network security thanks to various encryption levels, authentication, auditing, and user control to ensure security.

Integrated Energy Recovery
In a compressed air system, up to 90% of the electrical energy input can be converted into heat. Atlas Copco GA and GA+ compressors can be equipped with an integrated energy recovery system that recovers up to 75% of the input energy as hot air or hot water.

By making effective use of recovered energy, you can achieve significant energy cost savings and a high return on investment without compromising compressor performance.

The compressor′s waste heat can be recovered and converted into hot water for applications such as:
Heating heat exchangers
Hot water supply for laundries, industrial cleaning, and sanitary facilities
Industrial process heating
Canteens and commercial kitchens
Food, chemical, and pharmaceutical industries

Recovered hot air can be used for:
Primary or supplementary heating for offices and workshops
Industrial drying processes
