Most dental and surgical procedures employ a vacuum suction wand to help remove blood and/or saliva from a patient during a procedure. A single vacuum pump would likely work for this application, but it would waste a significant amount of energy and money by running constantly.
By adding an electronic pressure regulator to directly control the vacuum, it can be turned on only when needed. The QB3 offers high flow for vacuum control and it can be paired with custom potentiometers (such as a foot pedal) to activate and control the command signal, or amount of vacuum desired.
In this sketch, the QB3 is providing consistent vacuum control to a container. The wand draws vacuum from the container and deposits the liquids there, as well. The filter protects the QB3 from pulling unwanted liquids internally.
