About the series

Features and benefits of the GHS VSD+ series

The series at a glance

The integrated VSD technology automatically adjusts the pump output to the actual demand and thus reduces energy consumption. At the same time, the innovative motor design and the high oil retention ensure quiet operation, low environmental impact and a clean working environment.

The compact plug-and-play design allows simple installation with a small footprint. Thanks to long maintenance intervals, low operating costs and optional energy recovery, the GHS VSD⁺ is particularly suitable for continuous industrial operation.

Typical applications are plastics processing, glass, bottling, canning, woodworking, packaging, printing and paper, and meat packaging.

With the GHS VSD+ series, Atlas Copco offers a powerful range of oil-sealed screw vacuum pumps developed for high energy efficiency, quiet operation and reliable performance. The oil-injected screw technology allows reliable vacuum generation in continuous operation with a low maintenance effort. Thanks to the integrated VSD+ drive, the pump speed adapts automatically to the actual vacuum demand, providing a particularly energy-efficient solution for industrial vacuum applications with varying load.

Oil-sealed screw technology

The Atlas Copco GHS VSD+ series works with oil-injected screw rotors. The oil seals, lubricates and cools; the high oil retention keeps it inside the pump and ensures a clean working environment.

High energy efficiency

The integrated VSD+ drive automatically adjusts the speed of the pump to the actual vacuum demand. This can significantly reduce energy consumption under varying load.

Powerful and reliable

The robust screw technology allows reliable vacuum generation and durable operation. Long service intervals contribute to a low maintenance effort and low operating costs.

Operating principle

The Atlas Copco GHS VSD+ series works on the principle of oil-sealed (oil-injected) screw vacuum technology. Two intermeshing screw rotors turn in opposite directions inside the pump housing and convey the gas drawn in from the inlet to the outlet; as they do so, the trapped volume becomes smaller and the gas is compressed.

Oil is injected into the compression chamber. It seals the gaps between the rotors and the housing, lubricates and carries away the heat of compression. An oil separator then retains the oil and returns it to the circuit; the high oil retention ensures a clean working environment.

The robust design enables reliable, long-lasting and low-maintenance operation. The integrated VSD+ drive automatically adjusts the speed to the actual vacuum demand and thereby reduces energy consumption, particularly under changing operating conditions.

The GHS VSD+ series is suitable for numerous industrial applications that call for high energy efficiency, reliable performance and flexible operation under varying load.
