JZJX series rotary vane roots vacuum unit
Vacuum degree: -0.05Pa~267Pa
Air volume: 30 ~ 2500L/S
The JZJX series roots rotary vane unit consists of ZJ type roots pump as the main pump, and single-stage or two-stage rotary vane pump as the pump unit of the former stage. The unit has the characteristics of high vacuum degree and wide range of pumping speed. It is more suitable for the extraction of dry and clean gas. A small amount of water vapor can also be removed when there is a gas ballast. This series of units have been widely used in metallurgy, chemical industry, light industry, petroleum, medicine, printing and dyeing, electric appliance, electric vacuum, semiconductor, food, atomic energy, textile and other industries.
