GA 355 Air Compressor

Outstanding performance

GA 355-500 compressors provide high-quality compressed air in the harshest environmental conditions. Incorporating Atlas Copco oil-injected screw element, they provide a long and trouble-free life at the lowest possible operating cost.

Metal industry

QUALITY AND EFFICIENCY
Metal plants use compressed air for instrumentation, plant air and pneumatic conveying for raw materials or ash and are in need of an efficient solution to reduce their operating costs. Thanks to their innovative features, our GA air compressors meet this demand.

Mining industry

ROBUSTNESS AND RELIABILITY
Compressed air is vital for the mining industry: applications include dust bad filtration, service air, ventilation air and pneumatic tools.
The reliability and robustness of GA compressors will accomplish the job even in the harshest conditions.

Power plants

SMOOTH AND COST-EFFECTIVE OPERATION
Power plants run round-the-clock to supply vital energy. A continuous supply of compressed air is absolutely critical for trouble-free operation. GA air compressors provide a reliable source of compressed air of applications such as silt blowing and fly ash handling.

General industry

A SAFE AND RELIABLE POWER SOURCE
Many industrial companies use compressed air in their daily operations. Applications include pneumatic tools for cutting, drilling, hammering and grinding, pneumatic actuators and valves, ventilation systems, packing and palleting machinery and conveyer systems.
GA compressors are designed for ultimate performance and reliability.

Twin element series for highest efficiency and reliability

Atlas Copco GA 355 Air Compressor Components

1. Practical cooler cleaning

• Hinged fans, fan motors and cowls for easy cooler cleaning.
• Twin fans for optimal cooling.
• Axial cooling fans driven by separateTEFC electric motors (IP55 protection).

2. Superior air quality

• 3-step efficient oil separation process for low residual oil content in the compressed air (less than 3 ppm).
• Hinged cover for easy separator element change.

3. Protective air filtration

• Protects the air compressor components by removing 99.9% of dirt particles down to 3 microns.
• Extends the system lifetime.

4. Moisture separator as standard

A cyclonic moisture separator, with automatic and manual drain, mounted as standard, after the cooler block.

5. Twin element on single drive & gear casing

• Efficiencies far superior to designs using one large element or 2-stages.
• Extended lifetime due to reduced loads on bearings, rotors and gears.
• Highly efficient motor –TEFC protection (IP55), class F insulation.

6. Energy recovery

• The optional energy recovery system canrecover up to 75% of the compressor’s shaft power as hot water.
• The main module of the recovery system is integrated in the compressor.
• Recovered hot water can be used as preheated boiler feed water, space heating, showering or other industrial applications.

7. Elektronikon unit controller

• High resolution color display gives you an easy to understand readout of the equipment’s running conditions.
• Clear icons and intuitive navigation provides you fast access to all of the important settings and data.
• Monitoring of the equipment running conditions and maintenance status.

Highly recommended for heavy-duty industrial operations!
We purchased the Atlas Copco GA 355 Air Compressor from Sekes for our manufacturing facility, and its performance has been outstanding. It operates with remarkable energy efficiency, steady air supply, and reliable stability under high loads. Sekes provided fast shipping and exceptional technical support.
