Atlas Copco Air Compressors
The GA90 VSD is engineered to deliver stable compressed air performance while maintaining high operational efficiency. Its variable speed drive system allows the compressor to adapt output precisely to air-demand fluctuations, reducing unnecessary power consumption during periods of lower usage. This operational flexibility is particularly beneficial in facilities with changing load profiles, where maintaining energy efficiency is a priority.
The compressor integrates a 90 kW motor designed for continuous-duty industrial operation. At a maximum working pressure of 13 bar, the machine provides a Free Air Delivery range capable of supporting mid- to large-scale manufacturing, processing, and utility applications. With design airflow values reaching up to 300.6 l/s depending on speed and pressure, the unit ensures a reliable air supply without compromising stability.
Its water-cooled configuration contributes to temperature control under demanding environmental or process conditions. The maximum inlet and operating temperature rating of 46°C supports installation in warmer industrial environments without sacrificing performance reliability. The MK5S Touch control system enhances operational accuracy by offering real-time monitoring, diagnostic capability, and user-friendly interface navigation.
A durable floor-mounted design, combined with a compact footprint and a weight of 1056 kg, allows the compressor to integrate into existing system layouts with minimal structural changes. Reference conditions including 20°C inlet and cooling medium temperatures ensure that performance data remains clearly defined and reproducible.
Overall, the GA90 VSD offers controlled output, efficient energy usage, and stable air delivery, making it a dependable solution for industrial operators requiring consistent performance under varying demand conditions.
