  • Vacuum pumping system
    Patent number: 9664195
    Abstract: To overcome the problem associated with liquid or solid process debris from a vacuum process system falling into, and contaminating or damaging, a vacuum pumping arrangement used to evacuate the system, the inlet of the vacuum pumping arrangement is located lower than the outlet of the arrangement. This provides a net flow of gas pumped by the arrangement in a generally upwards direction thereby resisting the passage of contaminants into the arrangement.
