For additional safety against "Flooding Electronic Housing" with an explosive or hazard process gas, a
differential safety pressure switch can be installed to measure positive pressure between Electronic
Housing and discharge of the vacuum pump. In an event of discharge pressure is rising up against
PSIG main power will be cut off.
To avoid explosive or hazard process gas will enter the electronic / motor housing, a discharge
mounted isolation valve is recommended which will close and isolate automatically after differential
pressure has reached its limited value.
