Vacuum pumping

Vacuuming is the process of creating negative pressure by extracting ambient air or other gases in a sealed physical space.

Vacuuming physical spaces (such as containers) is one of the common applications of vacuum technology, which involves extracting ambient air or other gases until a set target pressure is reached.

The application fields of vacuum pumping are very extensive. This extraction process extensively utilizes vacuum chambers, which can perform manufacturing or testing processes that are hindered by the presence of ambient air or oxygen.

A typical example of vacuum pumping is the process chamber or space simulation chamber in the semiconductor industry, including vacuum furnaces or coating chambers.
