What is an oil-free lubricated compressor?

Oil-free lubricating compressor (referred to as "oil-free machine") is a kind of gas compression machinery, and there is no need to use lubricating oil to lubricate piston rings or packing in its cylinder. This means that in the process of compressing gas, the compressed gas does not contact with lubricating oil, thus ensuring the high purity of the output gas.

Core special requirements include:

Pure gas: compressed gas contains no oil and oil vapor, and does not need complicated oil-gas separation equipment. This is its value.

Low operating cost: there is no need to add cylinder lubricating oil frequently, and there is no need to replace oil filter and oil-gas separation core.

High safety: for flammable gases such as compressed oxygen, the cylinder is oil-free to avoid the risk caused by carbon deposition or oil mist.

Good environmental protection: it reduces the discharge and treatment of oily condensate.

Maintenance simplification: there is no sludge and carbon deposit in the cylinder, and the piston ring replacement is relatively simple.

Oil-free lubrication compressor is a kind of compressor which uses self-lubricating material (such as ptfe) instead of metal piston ring to ensure that compressed gas does not contact with lubricating oil in the cylinder. It sacrifices a certain life span of wearing parts in exchange for absolute cleanliness of gas, and is an indispensable core equipment in precision manufacturing, medical care and food industry.
