Additionally, the vacuum deaerator comprises a drive shaft configured to rotate the distributor plate, and at least one feed port configured to provide a liquid comprising entrained gases to a surface of the distributor plate. The distributor plate is configured to deaerate the liquid by substantially removing entrained gases from the liquid through the application of centrifugal force.
