Atlas Copco GHS 350-900 VSD+ rotary screw vacuum pumps

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

The GHS 350-900 VSD⁺ vacuum pump range is said to provide users with energy savings of around 50% compared to traditional rotary vane pumps, with its VSD and an innovative inlet control valve combining to reduce lifecycle costs. The product has a lower environmental impact due to ultrahigh oil retention at all operating pressures - from ultimate pressure to atmospheric pressure. It conforms to energy management and environmental commitments according to ISO 50001/14001.

The series offers a low noise level compared to other vacuum pumps. Energy recovery leads to minimal hot air in the workplace, while its oil retention means that the quality of the exhausted air is optimal. It also avoids oil spills on the factory floor, which commonly occur with conventional oil-lubricated pumps. This leads to a cleaner working environment and faster cycle times.

Due to its plug-and-play design, the series assures an easy and fast installation that saves time and space. The footprint is no larger than that of a standard pallet and everything required is delivered as a complete package.

The vacuum-specific element is said to offer a longer lifetime than a screw compressor and vane pumps, as well as high efficiency. The inlet control valve provides modulating vacuum control in conjunction with the VSD drive to minimise energy consumption.
