Oil-injected rotary screw compressors
Atlas Copco has enhanced three compressors in its GA series. The improved GA 30+, 37 and 45 compressors offer better performance, lower noise, and a smaller footprint. The free air delivery (FAD) and specific energy requirement (SER) of the GA 30+, 37 and 45 have both been improved by 1 percent. Each model offers low noise levels down to 65 dB(a) for extremely quiet operation. The GA 30+, 37 and 45 provide 30% smaller footprints than previous editions; the 60 hp version has a footprint as small as 52 inches long and 35 inches wide. The low noise levels and reduced size make it possible to install units on the work floor, reducing the energy consumption of transporting compressed air to the point of use.
