Atlas Copco GA55 Oil Injected Rotary Screw Air Compressor
Atlas Copco GA55 Oil Injected Rotary Screw Air Compressor Genuine Original Ready Stock Fast Delivery.
The Atlas Copco GA55 is a 55 kW oil injected rotary screw air compressor engineered for continuous duty industrial compressed air supply. Positioned in the mid-range of the GA series, this compressor is extensively utilized in manufacturing, automotive, food processing, and general industrial facilities that demand reliable, consistent compressed air throughout extended production shifts.
Key Features & Technical Specifications
- Optimized Air End Design: Specifically engineered for 55 kW power class with rotor profile, timing gear specification, bearing selection, and internal clearances designed for continuous operation within optimal thermal and mechanical parameters
- Elektronikon Controller: Advanced management system handling automatic load/unload cycling, continuous monitoring of key operating parameters, and proactive alerts for developing conditions before reaching fault levels
- Comprehensive Monitoring: Tracks oil temperature, discharge pressure, filter differential pressure, and running hours with service reminders programmed for scheduled maintenance intervals
- Acoustic Enclosure: Contains operational sound to levels suitable for installation in occupied plant rooms and production areas without additional noise isolation requirements
- Service Accessibility: Maintenance panels provide access to all scheduled service items without canopy removal, minimizing planned service downtime
Configuration Options
The GA55 is available in both fixed speed and variable speed drive configurations:
- Fixed Speed GA55: Delivers consistent output at rated pressure, ideal for applications with stable compressed air demand across operational shifts
- Variable Speed GA55 VSD: Continuously adjusts motor speed to match actual demand, significantly reducing energy consumption in applications with variable air demand between peak and off-peak periods

Frequently Asked Questions
Q: We are replacing an existing 55 kW compressor from a different manufacturer. Will the GA55 connect directly to our existing pipework and electrical supply, or do we need to plan for installation modifications?
Pipework connection size, electrical supply voltage, and phase configuration must be matched to the GA55 specifications. The GA55 is available in multiple pressure variants with corresponding outlet connection sizes. Electrical requirements differ between fixed speed and VSD configurations - the VSD variant includes an integrated frequency inverter with specific supply quality requirements regarding voltage stability and harmonic distortion. Provide your site supply voltage, existing pipework connection size, and available floor space dimensions for assessment of direct replacement feasibility or required modifications.
Q: Our production runs two shifts with significant air demand variation between day and night shifts. Which GA55 configuration provides better energy efficiency across the operating week?
For sites with consistent high-demand day shifts and materially lower night shift demand, the GA55 VSD configuration reduces energy consumption compared to fixed speed models when demand differential justifies VSD implementation. Fixed speed compressors cycling between load and unload during light demand consume power without delivering output. The GA55 VSD tracks actual demand and reduces motor speed during low-demand periods, eliminating unloaded running losses. Energy savings are proportional to the depth and duration of low-demand periods. Provide your approximate peak and off-peak flow requirements for VSD payback period calculation.
Q: We've experienced reliability issues with competitor compressors at this power level due to air end bearing failures around 20,000 hours. What is the expected air end service life on the GA55 under normal operating conditions?
Under normal operating conditions - correct inlet filtration, genuine lubricant at proper service intervals, operating within rated ambient temperature range, and stable supply voltage - the GA55 air end service life significantly exceeds 20,000 hours before major attention is required. Premature bearing failures in competitor equipment typically result from non-genuine lubricants, extended oil service intervals, inlet filter neglect allowing particulate ingress, or sustained operation above rated ambient temperatures. The GA55 air end is engineered for extended service life when maintained according to Atlas Copco specifications using genuine parts and lubricants. Provide your site ambient temperature range and current maintenance practices for customized service schedule recommendations.
