Atlas Copco GA75 VSD Air Compressor

The Atlas Copco GA75 VSD is a 75 kW variable-speed rotary screw air compressor built for factories that run compressed air all day and want to stop paying for air they don’t use. As a China-based Atlas Copco supplier, we keep genuine GA75 VSD units in stock with worldwide delivery — request a live quote below.

The GA75 VSD from Atlas Copco is designed to support industrial operations that require continuous, adjustable compressed-air delivery. Its 75 kW drive system operates in combination with a variable-speed mechanism, enabling the compressor to respond dynamically to changes in air demand. This approach promotes stable pressure control at up to 13 bar while preventing unnecessary full-load operation during light-duty cycles. The water-cooled arrangement also contributes to consistent operating temperatures, particularly in applications with extended duty cycles or in enclosed mechanical rooms.

Performance flexibility is a central characteristic of this unit. With Free Air Delivery values ranging from under 30 l/s at low speed to over 190 l/s at high speed, the compressor can be integrated into production systems with varying air-flow requirements. The MK5 Touch controller further enhances operational reliability by presenting real-time performance data and allowing supervisors to monitor system behavior more accurately. This type of monitoring reduces the likelihood of unplanned shutdowns and supports routine maintenance planning.

Physically, the GA75 VSD is constructed with a reinforced frame and a compact form factor, allowing integration into established compressed-air networks without requiring major structural changes. Environmental tolerances, including an inlet temperature limit of 46°C and a minimum ambient rating of 0°C, help ensure dependable operation in varied industrial settings. These combined attributes make the GA75 VSD a practical choice for facilities seeking a stable, well-regulated, and adaptable compressed-air supply system.

Where the GA75 VSD fits best

With variable air delivery from 27.6 up to 193.5 l/s at 13 bar, a single GA75 VSD comfortably supplies mid-to-large plants — automotive workshops, textile mills, food & beverage lines, plastics and packaging, and central air stations feeding multiple machines with fluctuating demand.

How much energy does VSD save?

Because the motor speed tracks real-time air demand instead of running full-load and blowing off excess air, a GA75 VSD typically cuts energy use by 30–50% versus a fixed-speed 75 kW unit in plants with variable load. Since electricity is around 70% of a compressor’s lifetime cost, that difference often pays back the price gap within the first year or two.

GA75 VSD vs fixed-speed GA75

Choose the GA75 VSD if your air demand swings during the day or across shifts. If your plant runs a steady, near-constant load 24/7, the fixed-speed Atlas Copco GA75 may be the more economical choice. Not sure? Send us your working hours and we’ll model both for you.

Atlas Copco GA75 VSD – FAQ

What is the FAD (air delivery) of the GA75 VSD? It varies with load, from about 27.6 l/s at minimum speed up to 193.5 l/s at maximum speed (219.7 l/s at design pressure).

What is the working pressure and motor power? 75 kW installed motor power, with working pressure up to 13 bar(g).

Does the GA75 VSD have a built-in dryer? This configuration ships without an integrated dryer; we can pair it with a matched refrigerated or desiccant dryer on request.

Is it air-cooled or water-cooled? Water-cooled, which holds stable temperatures in enclosed compressor rooms and during long duty cycles.

How much does an Atlas Copco GA75 VSD cost? Price depends on voltage and configuration; use the quote form for a current delivered price to your port.
