Atlas Copco Launches New GHS 402-902 VSD⁺ Oil-Lubricated Screw Vacuum Pump Series
2026/07/09
Date: June 2026
Atlas Copco has introduced the new GHS VSD⁺ vacuum pump series, taking vacuum technology to a new level. The GHS 402–902 VSD⁺ models are equipped with a next-generation oil-injected screw element, a highly efficient IE5 motor, and advanced HEX@™ connectivity, delivering intelligent performance, longer maintenance intervals, lower operating costs, and an overall lower environmental impact.
Whereas vacuum systems used to consume energy regardless of demand, modern oil-sealed screw pumps are efficient systems that deliver vacuum according to demand. The GHS 402–902 VSD⁺ features constant-pressure setpoint control, matching vacuum output to the exact flow needed at any moment. This second-generation pump delivers high pumping speeds from atmospheric pressure through to ultimate vacuum, resulting in significant energy savings and faster pump-down performance.
The series is particularly suitable for food packaging, vacuum cooling of flowers and vegetables, and thermoforming of plastics and white goods.
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 cleaner exhaust and reduced environmental impact.
Key advantages of the GHS 402–902 VSD⁺ include:
- Modern oil-injected screw element with compression optimization valves
- Compact design with footprint of less than 1 m²
- Recovery of up to 80% of pump heat as reusable hot water
- HEX@™ intelligent controller enabling Industry 4.0 features
- Lower noise levels, better oil retention and longer maintenance intervals
“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," reports Product Manager Ilias Alafogiannis.
