Oil Free Vacuum Pump

Micro oil screw vacuum pump is a new type of vacuum equipment designed with a screw. It achieves gas pumping by synchronously rotating a pair of asymmetric screw rotors in reverse and periodically changing the inter tooth volume. Its core feature is the use of trace lubricating oil (oil content<2PPM) to form a sealed oil film, which combines the cleanliness of a dry pump with the efficiency of an oil lubricated pump. This pump has significant advantages: high efficiency and energy saving (more than 30% energy-saving compared to traditional pumps, with a volumetric efficiency of 95%), low-noise operation (55-85dB), simple structure and easy maintenance, and can adapt to complex working conditions with water vapor, dust or corrosive gases. Mainly used in fields such as pharmaceuticals, chemicals, semiconductors, etc. that require strict clean vacuum requirements, it also plays an important role in industries such as food packaging, electronic manufacturing, and oil extraction, making it particularly suitable for industrial scenarios that require long-term continuous operation.
