Oil-free air compressor by what lubrication

Oil-free air compressors mainly rely on special lubrication methods to ensure their efficient and stable operation without the use of traditional lubricants. Specifically, oil-free air compressor can use the following lubrication methods:

water lubrication: Some oil-free air compressors use water as a lubricating medium, which is called water lubrication. Through the flow of water, the lubrication, cooling, sealing and noise reduction of the compressor are realized. This method not only provides high-quality oil-free air, but also discharges water without special treatment, which meets environmental protection requirements.

Resin or other oil-free materials: Some oil-free air compressors use resin or other oil-free materials as lubricants. These materials play a lubricating role inside the compressor while avoiding the mixing of oil and gas.

gearbox internal lubrication: Although oil-free air compressors do not use oil in the compression chamber, their gearbox may contain oil. This oil is mainly used to lubricate the gears and bearings inside the gearbox, as well as the bearings and timing gears located inside each compressor element. This type of lubrication ensures long-lasting stable operation of the gearbox and internal components.

In general, the oil-free air compressor achieves efficient and stable operation under oil-free conditions by using water lubrication, resin lubrication and gearbox internal lubrication. These lubrication methods not only ensure the purity of compressed air, but also meet the requirements of environmental protection, making oil-free air compressors widely used in many industries.
