Gas Ballast Control Knob, Edwards RV Series - A65201008
The RV series pumps are the industry standard. Over 400,000 units have been sold . They are tough and reliable. But they have one common vulnerability: water vapor and other condensable gases.
If you pump steam or solvents, they can condense inside the pump. They mix with the oil. The oil turns milky. It loses its lubricating properties. Your vacuum performance drops.
The solution is the Gas Ballast .
