Oil Sealed Screw Vacuum Pumps

Ideal for diverse markets

Our Atlas Copco screw vacuum pumps are ideal for a range of applications in plastics, glass, bottling, canning, wood, packaging, printing and paper, meat packaging and many more. The GHS 350-900 VSD+ is an optimal solution when a dedicated pump is required in the production area/

Low lifecycle costs

For replacement pumps, the GHS VSD+ Series offers a very low lifecycle cost (including service activities and energy). Generally the payback time against existing oil-lubricated or multiple dry vane installations will be much less than two years, considering energy consumption and maintenance costs alone, without taking into account the ease of installation.

VSD+ for potential energy savings of 50%* or more

In almost every production environment, the need for vacuum fluctuates depending on different factors such as process changes, the time of day, week or even month. Extensive measurements and studies of demand profiles show that there are many substantial variants with regards to vacuum demand. *In most applications compared to traditional fixed speed vacuum technologies based on measurement with our Vbox energy audit tool. Fixed Speed Vacuum Pump Energy Investment Maintenance GHS VSD+ SAVINGS 50%*

Why Atlas Copco Variable Speed Drive (VSD) technology?

  • Potential energy savings of 50%* or more with an extensive flow range (20-100%)
  • Reduced electrical installation costs (fuse and cable size)
  • Integrated HEX@â„¢ graphic controller controls the motor speed and high efficiency frequency inverter
  • Eliminates peak current penalty during start-up experienced with stop-start machines

Energy savings

VSD and set-point control, lead to significant energy savings. Set-point control allows you to optimize the energy you use to maintain your process vacuum level and thereby optimize your process efficiency and performance. The lowest possible flow will be delivered to match your required vacuum level or speed – nothing is wasted.

Game-changing Variable Speed Drive Technology For Vacuum Pump


Dry Screw Vacuum Pumps

At Ash Air, our dedication to customer satisfaction and environmental responsibility drives our innovation forward. We prioritize investments in advanced technology, such as our line of dry screw vacuum pumps. These pumps offer numerous benefits, including increased productivity, reduced energy consumption, user-friendly controls, simplified maintenance, and lowered operational costs.

Clean technology

Our range of dry screw vacuum pumps are friendly on the environment – with no contaminated oil to dispose. Dry technology means no exhaust emissions and a clean, reliable performance.

Clever technology

Our DHS VSD+ and DWS VSD+ range of dry screw vacuum pumps feature Variable Speed Drive (VSD) technology. The pump adjusts vacuum flow as per your process demands and optimizes energy consumption leading to substantial energy savings.

Connected technology 

Benefit from always-on connectivity and remote monitoring with ElektronikonTM for advanced pump monitoring such as status, running and stopped hours, programmable timers, set point control among other parameters.
