The Roots-screw vacuum unit is a composite high-efficiency vacuum system composed of a dry screw vacuum pump as the front-stage pump and a Roots vacuum pump as the booster pump, integrating the superior performance of two core vacuum devices. This combined structure perfectly makes up for the performance limitations of a single vacuum pump, realizing fast pumping speed, high ultimate vacuum and stable operation, which is widely used in medium and high vacuum industrial scenarios with strict working requirements.
Roots-Screw Vacuum Unit provides stable and efficient preliminary vacuumizing, featuring oil-free operation, clean air extraction and strong condition adaptability, which can quickly discharge a large amount of gas and avoid gas accumulation. Roots-Screw Vacuum Unit further increases the system's pumping speed and compression ratio, effectively lifting the vacuum degree in the medium vacuum stage and solving the problem of slow vacuum forming of a single screw pump. The two pumps operate in intelligent linkage to achieve gradient vacuumizing, greatly improving overall working efficiency.
The whole unit adopts a fully dry oil-free design throughout the working process, with no lubricating oil involved in the gas flow path, completely eliminating oil pollution and ensuring ultra-clean vacuum environment. It supports 24-hour continuous uninterrupted operation, with low vibration, low noise and low failure rate. Equipped with an intelligent linkage control system, the unit can automatically match operating parameters according to pressure changes, realizing energy-saving and stable automatic operation.
With the advantages of fast vacuum response, wide vacuum adjustable range and strong pollution resistance, the Roots-screw vacuum unit is widely applied in pharmaceutical production, fine chemical processing, vacuum coating, electronic manufacturing and industrial degassing. It provides reliable, clean and high-efficiency vacuum power for high-precision and high-standard industrial production processes.
