Atlas Copco developed the GHS 402-902 VSD⁺ vacuum pump, in which the process vacuum depends on the flow requirement and is controlled by constant pressure setpoint control in the vacuum. This second generation of the pump brings innovation delivering high pumping speeds – from atmospheric pressure to ultimate pressure. For users, this results not only in energy savings but also to faster pump down performance. With these attributes, the GHS 402-902 VSD+ is particularly suitable for food packing, vacuum cooling of flowers and vegetables and thermoforming of plastics and white goods.
Atlas Copco’s GHS 902 VSD⁺ vacuum pump
The GHS 402-902 VSD⁺ models set the benchmark in vacuum performance. Equipped with the company’s next-generation oil-injected screw element, a highly efficient IE5 motor and advanced HEX@™ connectivity, these pumps deliver intelligent performance, longer maintenance intervals, lower operating costs and an overall lower environmental impact.
“With higher pumping speeds and class-leading efficiency across the entire pressure range, the GHS 402-902 VSD⁺ dramatically cuts power usage – directly improving our customers’ bottom line while supporting their sustainability goals,” said Ilias Alafogiannis, Product Manager, Atlas Copco.
With a new vertically mounted, fully integrated oil-cooled drivetrain, the GHS 402-902 VSD⁺ series delivers clear ergonomic and operational advantages, including lower noise levels and a compact footprint of less than 1 m². The optimized oil-separator vessel further enhances oil retention, ensuring a cleaner exhaust and reduced environmental impact.
“With a design 30% more compact and oil-discharge levels cut by half compared to previous models, combined with a noise-dampening canopy, these pumps are ideal for both central vacuum systems and point-of-use applications, bringing significant improvements to the working environment of any production facility,” said Alafogiannis.
