On Hannover Messe 2013, Atlas Copco surprised the market with a new, very compact oil-injected rotary screw compressor from 7 to 37 kW: the 7-37 GA VSD+. Besides a small footprint, it offers a leap forward in Free Air Delivery (improvements of up to 12%), and a breakthrough energy-efficiency: it requires on average 50% less energy than a comparable idling compressor. This new type of compressor offering a variable speed (frequency-controlled), will be suitable for most industries and aims to contribute significantly to the green economy needs.
