The Roots screw vacuum unit is composed of two Roots pumps and screw pumps in series, and is equipped with pipelines, valves, racks and electrical control boxes, etc. After the current stage screw pump works, it is controlled by the vacuum gauge head and vacuum relay. Roots pump starts. Since the rotating parts of the Roots pump and the screw pump are non-contact parts, the unit has the advantages of stable operation, low noise, low vibration, compact structure and small footprint.

Application: Due to its obvious energy saving effect, large air extraction capacity in high vacuum area and high vacuum degree, the double roots screw vacuum unit is an ideal air extraction equipment for electrical, electronic coating, smelting, heat treatment, drying, distillation, pharmaceutical, chemical, and other industries. It is especially suitable for the semiconductor industry that requires no oil vapor pollution, and it is also suitable for occasions containing a large amount of water vapor and a small amount of dust. According to the different requirements of vacuum degree, you can choose single Roots screw vacuum unit or double Roots screw vacuum unit

Application range of double roots screw vacuum unit:
1. Chemical and pharmaceutical: product distillation, drying, degassing, material conveying, etc.
2. Electrician: transformer, transformer, epoxy resin vacuum casting, capacitor vacuum immersion oil, vacuum pressure immersion.
3. Aerospace: Space carrying spacecraft orbital module, return module, rocket attitude adjustment module, space suit, astronaut space exit, aircraft liftoff and other vacuum simulation experiments.
4. Vacuum coating: vacuum evaporation coating, vacuum magnetron sputtering coating, film winding continuous coating, ion plating, etc.
5. Industrial furnaces: vacuum brazing, vacuum sintering, vacuum annealing, vacuum pressurized gas quenching, vacuum detangling, etc.
6. Drying: kerosene gas phase drying, pressure swing vacuum drying, wood drying, freeze drying of vegetable food, etc.
7. Metallurgy: Special steel smelting, vacuum induction furnace, vacuum desulfurization, degassing.
