Evacuation with Vacuum

Where is vacuum used in evacuation applications?
The evacuation of containers, such as the extraction of air or gas from closed containers, is one of the most widespread applications of vacuum technology. These applications are consequently highly diverse.

Evacuation is generally understood to be emptying a physical space of gases, in most industrial applications of ambient air. Evacuation chambers are used in various applications to conduct manufacturing or testing processes that would be impeded by the presence of ambient air, or in some cases by the presence of oxygen.

The level of vacuum required varies between applications, from low vacuum for central vacuum cleaning or clean rooms to high vacuum for silicon wafer coating in semiconductor production.

Which Busch vacuum solutions are especially suitable for evacuation processes?
A huge variety of applications involve the evacuation of containers, and the range of vacuum pumps available for these applications is equally diverse. Key factors to consider when selecting a vacuum generator include the volume to be evacuated and the required ultimate pressure in the container. Nearly all of the vacuum pumps in our product range can be used to meet requirements of this kind.

R 5 rotary vane vacuum pumps are used in many different evacuation processes, where they excel due to their operational reliability and robustness.

Mink claw vacuum pumps are practically maintenance-free due to their non-contact, oil-free operation. These energy-saving vacuum generators are used in evacuation processes that involve processes in the low vacuum range.

COBRA screw vacuum pumps are particularly suitable for applications involving the extraction of corrosive or explosive gases. The dry screw technology used by COBRA vacuum pumps permits high levels of vacuum to be achieved.

For high vacuum evacuation processes, we recommend vacuum systems comprised of R 5 or COBRA vacuum pumps combined with rotary lobe boosters from the Puma or Panda series. For small volumes, we advise evacuation with Zebra rotary vane vacuum pumps. Other pump combinations suited to high vacuum evacuation processes include Turbo turbomolecular or Rangu diffusion vacuum pumps.

Common evacuation applications are for example:

  • Vacuum Packaging – Evacuation of packaging chambers (see > Vacuum Packaging)
  • Vessel Vacuum Systems –  Permanently maintained vacuum levels in vacuum containers
  • Heat Treatment – Evacuation of vacuum furnaces
  • Surface Coating – Evacuation of coating chambers
  • Mold Evacuation –  Quality optimization in many casting processes
  • Space Simulation –  Evacuation of space simulation chambers
  • Transfer Chambers – Used in wafer production
  • Process Chambers – Mainly used in semiconductor production
