Atlas Copco Compressors has introduced the next generation of the 40 to 125 horsepower GA oil-injected screw air compressor range, featuring improved components that provide unparalleled performance, sustainability, efficiency and reliability. The range includes three options: the GA 37-90 VSD (50 to 125 hp), the GA 30+-75+ (40 to 100 hp) premium fixed-speed variant, and the GA 37-90 (50 to 125 hp), which delivers solid performance and Free Air Delivery (FAD) in a base package. The GA 30+-75+ VSD can deliver an average 35 percent energy savings, while eliminating compressor idle time and blow-off loss; starting up under pressure reduces life cycle costs up to another 22 percent. The premium efficiency fixed-speed variant GA 30+-75+ offers industry-leading efficiency and best in class FAD. An improved layout beneath the GA’s “cool canopy,” combined with its single-ducting principle, help drive performance, efficiency, and serviceability.
Atlas Copco has also introduced IE3/NEMA premium efficiency motors, in combination with high-efficiency screw elements, for all ranges. As a result of these features, temperatures at the GA’s element have decreased by an average of 18 degrees F.The integrated design and industry-leading low noise operation of the new GA range allows the compressor to be placed right at the heart of the production environment. Combined with the integration of the air and condensate treatment equipment, the new GA range offers complete versatility for the customer. The GA’s integrated dryer, an option for all machines in the range, uses an environmentally friendly refrigerant (R410A) that reduces the dryer’s power consumption by up to 50 percent and does not contribute to ozone depletion. The next generation GA line also includes a number of improvements to the oil-treatment system, resulting in up to 50 percent less oil use and reduced maintenance demands. And the air compressor’s condensate can be safely disposed of directly into a sewage treatment system, due to the GA’s integrated condensate treatment, making it suitable for ISO 14001 certified companies. The new GA line also features Atlas Copco’s Elektronikon®, the compressor control system that provides system managers with round-the-clock remote monitoring capabilities. An “app” is also available to allow remote monitoring from smart devices In addition to increased cooling capabilities, the GA’s new electrical cubicle also features a forced air cooling system, which draws in less conductive dust and particulate matter, extending the life of the internal electrical components.
