The difference between oilless screw compressor and oilless screw compressor

Both oil-free screw compressors and oil-containing screw compressors adopt screw rotor compression technology in terms of core principles, but there are essential differences between the two in terms of lubricating medium and gas purity:

1. Differences in lubrication methods
Oil-containing screw compressors achieve rotor sealing and cooling by injecting lubricating oil, and require an oil separation system to reduce the oil content of the gas; oil-free screw compressors use water or other non-oily media instead of lubricating oil to avoid the risk of oil pollution from the root cause.

2. Gas purity comparison
The gas compressed by oil-containing equipment may still leave traces of oil after being filtered through multiple stages, which is not suitable for scenarios with strict requirements for gas cleanliness; the gas produced by oil-free equipment is completely free of oily substances, which can directly meet the needs of medical surgery, Food processing and other industries. Gas standards.

3. Maintenance costs and environmental protection
Oiled compressors require regular replacement of lubricating oil and filter elements, and the maintenance process is complex and requires waste oil treatment. Oil-free equipment does not require an oil system, which greatly simplifies the maintenance steps. At the same time, the water lubricating medium has degradable characteristics, which is more in line with environmental protection requirements.

Technical analysis of Glanklin water-lubricated single screw compressor
The precise meshing design of a single screw and a star wheel is adopted, and pure water is used as the sealing and cooling medium to achieve complete oil-free gas output. This technology ensures efficient and stable compression process through the combination of machining accuracy and intelligent control system, and is especially suitable for scenarios with extremely high gas cleanliness requirements such as hospital oxygen generation systems and dental diagnosis and treatment equipment. Its oil-free characteristics eliminate the risk of oil pollution, and the water lubrication method also reduces equipment operating noise and maintenance complexity, providing reliable gas-dynamic solutions for precision industries such as medical and food.
