What is a gas ballast? Vacuum pumps designed for pumping vapours are generally equipped with a 'gas ballast' control. The gas ballast allows a controlled amount of gas, generally air from outside the pump, to be introduced into the pumping mechanism. Typical applications would include rotary evaporation, distillation and gel drying.

"The purpose of a gas ballast in a vacuum pump is to prevent water vapors from condensing during the discharge stroke of the vacuum pump. Water can only be removed from a system in vapor form. If the atmosphere that you are removing from the refrigeration system is moisture laden, as that moisture enters the pump .
The gas ballast valve in most pumps 'meter in' a controlled amount of atmospheric gas into the compression cycle of the pump, thus 'diluting' the amount of vapour that is being compressed. All high vacuum pumps have a maximum amount of water vapour tolerance i.e. the quantity of water that the pump can successfully pump .
