Atlas Copco re-engineered its range of small GA compressors (15-40 hp GA+/GA VSD) to provide greater energy savings for dealer. The result is a combination of world-class free air delivery (FAD), increased efficiency, a smaller compressor footprint and lower noise levels. According to the company these engineering breakthroughs have increased FAD from 7% to 17% over previous GA models and from 9% to 24% for the GA VSD. In addition, the company said the new models use up to 80% less space compared to similar compressors on the market, and operate at noise levels as quiet as 63 dBA. The line is further improved through high resistance to dust and high temperatures, Atlas Copco said.
