GA series is ISO 9001, ISO 14001 and ISO 1217 compliant. Long and trouble-free life at the lowest operating cost

Advanced Design
Latest generation of our innovative oil-injected screw element included

Reduced Energy Costs
Reduced lifecycle costs thanks to the use of a superior screw element and a high efficiency motor. VSD reduces energy costs by 35% on average

Integrated Air System
GA WorkPlace Air System delivered ready for use. No need for a separate compressor room. Low-noise operation, compact size and integrated air treatment equipment. Integrated options significantly reduce pressure drops to save energy

Easy Installation
The compact, integrated design of GA 5-500 compressors includes internal piping, coolers, motor, lubrication and control system – all supplied as a ready-to-use package. Installation is fault-free and commissioning time is low. Simply plug and run

Air Treatment Integration
Full Feature GA compressors have an integrated dryer and oil-water separator to protect your compressed air network. The high-quality air extends the life of equipment, increasing efficiency and ensuring quality in your final product.

Oil injected screw compressors designed for efficiency

The components of the oil-injected rotary screw compressors have been carefully designed in house. This reduces losses and pressure drop to a minimum, resulting in the highest compressor package efficiency. The air compressor also uses reliable components to guarantee operation in the toughest environments and running conditions. By using our rotary screw technologies you are guaranteed to a reliable and efficient compressor.

Advanced monitoring system
Most production processes create fluctuating levels of demand. This creates energy waste in low air demand periods. Using the Elektronikon® unit controller, you can manually or automatically switch between two different setpoints to optimize energy and reduce cost.   In addition, the sophisticated algorithm runs the drive motor only when needed. As the desired setpoint is maintained while the drive motor’s run time is minimized, energy consumption is kept to a minimum.

Variable Speed Drive
Over 80% of a compressor's lifecycle cost is taken up by the energy it consumes. The generation of compressed air can account for more than 40% of a plant's total electricity bill. To cut your energy costs we've pioneered in Variable Speed Drive (VSD) Technology in the compressed air industry.   Atlas Copco's VSD technology closely follows the air demand by automatically adjusting the motor speed. This results in energy savings of up to 35%.

Recover your energy
Our oil injected compressors use an integrated energy recovery system. It recovers up to 78% of the energy from the motor and the element oil circuit. Through efficient usage of the recovered energy, you generate important energy cost savings and a high return on investment.

Monitor your system
It's important to know the status of your compressed air system. You want to achieve optimal efficiency and maximum availability. With SMARTLINK you can monitor your compressed air installation. Monitoring your system not only saves you money, but also avoids breakdowns and production losses.

Matching your specific requirements
Our GA oil-injected screw compressors bring industry-leading performance, flexible operation and high productivity, reduced enargy costs at a minimal cost of ownership. A wide range of compressors enables you to find the air solution that perfectly matches your specific requirements. Built to perform in even the harshest environments, an Atlas Copco GA keeps your production running efficiently.

Exceptional energy savings
Atlas Copco’s VSD⁺ technology closely follows the air demand by automatically adjusting the motor speed to match the compressed air supply to the demand. Combined with the innovative patented iPM (interior Permanent Magnet) motor (IE4), the GA VSD⁺ achieves average energy savings of 50%. This reduces the total lifecycle costs of the compressor up to 37% on average.

On top of energy savings up to 50% , the GA VSD⁺ realizes a Free Air Delivery (FAD) increase of up to 12% for improved efficiency and performance.
