Atlas Copco GA55 VSD Air Compressor

Atlas Copco designed the GA55 VSD to deliver stable compressed-air performance under varying demand while maintaining controlled energy consumption. With an installed motor power of 55 kW and the ability to regulate output through variable-speed technology, the unit adjusts compressor speed according to the air requirement, reducing periods of unloaded operation. This is particularly relevant in facilities where flow demand fluctuates, supporting more consistent system pressure and limiting energy waste.

The air-cooled configuration simplifies installation by eliminating the need for external cooling circuits, and the 46 °C maximum inlet and ambient operating temperature rating enables continuous operation in demanding industrial environments. The compressor structure incorporates a compact footprint relative to its output class, supported by a height of 1968 mm and width of 1100 mm. The 876-kg frame offers appropriate rigidity for long-term operation while maintaining service accessibility for routine maintenance.

Performance values show maximum-speed free air delivery levels above 160 L/s at effective working pressure, providing adequate capacity for medium-to-large manufacturing processes. Variable-speed adjustment also ensures reduced mechanical strain during start-up, contributing to component life preservation. The MK5 Touch control interface monitors operating conditions and provides system diagnostics, supporting preventive maintenance planning.

Across continuous-duty applications, the GA55 VSD provides predictable output, controlled energy use, and operational reliability. These characteristics make it suitable for production facilities requiring a consistent compressed-air supply with the flexibility to adapt to variable operational loads.
