20Nm3/h 250bar High pressure Oil-free Oxygen/ Nitrogen/ Argon Reciprocating Gas Compressors

High Quality Oil-free Oxygen Nitrogen Argon Gas Compressors 

Minwen high pressure argon compressor belongs to oil-free reciprocating piston type construction. it is divided into three-stage, four-stage or five-stage compression according to the displacement and pressure. It is divided into air-cooled type and water-cooled type according to the cooling type.
There is no lubricating oil inside the argon compressors, grease lubricated sealing type bearing is adopted for the rotary moving components, the moving seals inside the cylinder are made of self-lubricating material so as to ensure that the compressed gas will never contact any oil; besides, it can be used to compress gas medium with stable properties like clean air, nitrogen, carbon dioxide, etc. The machine adopts automatic control mode with low leakage and noise and without the need to arrange dedicated person for attention, and can operate over long term reliably. 
An oil-free compressor is a type of air compressor that operates without the need for lubricating oil in the compression chamber. Traditional air compressors use oil to lubricate the moving parts and provide a better seal between the compression chamber and the piston or rotor. However, in certain applications where oil contamination is a concern, such as medical and dental facilities, food processing, electronics manufacturing, and painting, oil-free compressors are preferred.

Oil-free compressors offer several advantages, including:

1. Oil-Free Gas: They deliver high-quality, oil-free compressed gases, which is essential in applications where oil contamination can be detrimental to the end product or process.

2. Reduced Maintenance: Oil-free compressors eliminate the need for oil changes, filter replacements, and oil disposal, resulting in lower maintenance requirements and costs.

3. Environmental Friendliness: The absence of oil reduces the risk of oil leaks or spills, making oil-free compressors environmentally friendly.

4. Improved gas Quality: Oil-free compressors provide cleaner gases, free from oil aerosols or vapors, which is essential in sensitive applications like medical and dental procedures or electronics manufacturing.
