Atlas Copco GHS VSD+ Series vacuum pumps

The GHS VSD⁺ Series is a range of efficient, intelligent vacuum pumps with variable speed drives (VSD) from Atlas Copco. Based on the plug-and-play design principles of Atlas Copco compressors, the vacuum pumps have been designed to deliver peak performance at operating pressures commonly found in industrial applications.

The series offers energy savings of around 50%. A VSD and an innovative inlet control valve combine to produce an increase in efficiency to reduce lifecycle costs. The pumps are claimed to be quieter, with noise levels well below that of comparable technologies. The series also conforms to energy management and environmental commitments according to ISO 50001/14001 and offers a reduced environmental impact due to ultrahigh oil retention at all operating pressures - from ultimate pressure to atmospheric pressure.

Energy recovery leads to minimal hot air in the workplace - avoiding the usual problem of hot air in air-conditioned production environments - while the high oil retention means the quality of the exhausted air is optimal, which contributes to employee well-being. It also avoids oil spills on the factory floor, which commonly occur with conventional oil-lubricated pumps.

The series will be expanded to include sizes up to 2000 m³/h by mid 2015 and up to 4500 m³/h in early 2016.
