Atlas Copco has applied its expertise in air compressors to vacuum pump technology with the launch of its new GV oil-sealed rotary screw vacuum pump system, suitable for ‘rough vacuum’ between 0.5mbar and 500mbar. Synergies between compressed air and vacuum technology, enable Atlas Copco to design and manufacture its own vacuum pump systems with the same quality and reliability as those of its compressors.

At the heart of the new GV vacuum pump is Atlas Copco’s expertise in the design and manufacture of screw elements. In the 0.5mbar to 500mbar operating pressure range, oil-sealed rotary screw technology is said to offer  the best performance at the lowest energy cost.

Thanks to its modulating valve, fitted at the pump inlet, the capacity of the pump can be matched to actual demand. This not only minimises the system’s vacuum level fluctuations, but also operates the pump at the lowest possible energy point. Another benefit is that due to this feature the vacuum pump also has to stop and start less frequently, leading to less wear and maintenance and therefore increased reliability.

The GV vacuum pumps deliver capacities between 20 and 5,000m3/h, making them suitable for many ­applications.

From printing and packaging to plastics, electronics, woodworking, bottling and canning, the GV is said to deliver consistent and efficient vacuum. Thanks to its quiet operation, the GV can be installed close to the point of use. However, they can also be installed as a remote installation as part of a centralised vacuum system.

Atlas Copco can now outfit complete systems with both compressed air, low pressure air and vacuum. To customers, this means one supplier and one service technician. Koen Lauwers, vice president marketing to the industrial air division, notes: “In the months to come, Atlas Copco expects to launch more new vacuum pump technologies and systems.”
