The rotary vane vacuum pump can be used as a main pump alone or as a fore pump for a booster pump, diffusion pump, and a molecular pump. It can also be used as a holding pump for a vacuum system or as a pre-pump for different types of pumps.
 

The 2XZ series rotary vane vacuum pump can work continuously for several hours at an atmospheric temperature of 5 ° C to 40 ° C and an inlet pressure of less than 1230 pa.
 

The 2XZ vacuum pump is equipped with a gas ballast valve. Its function is to fill the exhaust space with a certain amount of air when the valve is opened, thereby reducing the proportion of the vapor partial pressure in the total exhaust pressure.
