Sweden-based industrial productivity solutions provider Atlas Copco's Industrial Air Division has introduced the 7-37 GA Variable Speed Drive+ (VSD+), an oil-injected rotary screw compressor that features a compact design and improved energy efficiency.
According to Atlas Copco, the new compressor requires 50 percent less energy on average than a comparable idling compressor, with features including a more efficient fan; a robust air intake system that removes all blow-off losses; top-of-the-line electronic components; a new drive train; and low noise levels. In addition, Atlas Copco reports the 7-37 GA VSD+ realizes a free air delivery increase of up to 12 percent; and is 15-percent more efficient than the earlier generation GA 7-37 VSD. An optional integrated dryer is available as an add-on.
