Atlas Copco expands GA VSD+ compressor range

Atlas Copco has expanded its range of GA VSD+ compressors with a series of extra models that are said to deliver efficiency in a space-saving upright format. Building on the success of the GA 7-37 VSD+ oil-injected rotary screw compressors. The range has been expanded up to 75kW to give more industrial air users the option of having an energy saving VSD+ model.

The GA VSD+ compressors use highly efficient iPM (Permanent Magnet) motors, a patented compression element and a sentinel valve. These technologies allow the range to deliver greater energy savings than the first generation of VSD compressors: average energy savings of 50% compared with fixed-speed alternatives. Free Air Delivery (FAD) and Specific Energy Requirement (SER) are both claimed to be improved by up to 9%. This means customers get up to 9% more air while using up to 9% less energy with the GA VSD+ compared to the GA VSD.

What’s more, the compact design of the GA VSD+ compressors fit better in confined spaces. The GA 7-75 VSD+ models are smaller and taller than the traditional GA (VSD) range, with a 60% reduced footprint.

Thanks in part to an innovative cooling fan, the GA VSD+ compressors produce 67dB, one of the lowest noise levels in the industry. Meaning they can be installed on the work floor rather than having to be housed in a separate room.
