Oil-free or oil-free air compressor which can avoid corrosion

Oil-free air compressor has more advantages in avoiding corrosion it effectively reduces the risk of rust through oil-free design, material selection and simplified maintenance, while oil-free air compressors rely on lubricating oil for rust prevention, which poses potential risks. The following is a detailed comparative analysis of the two:

principle and advantage of oil-free air compressor to avoid corrosion

1. oil-free design to reduce pollution: The oil-free air compressor does not use lubricating oil in the process of compressing air, so it will not produce oil pollution. Oil is one of the important causes of corrosion, it may adhere to the metal surface, and moisture, oxygen and other joint action, accelerate the corrosion process. The oil-free design fundamentally eliminates this hidden danger.
2. Material selection to enhance rust resistance: Oil-free air compressor, especially oil-free screw air compressor, its internal whole is made of stainless steel. Stainless steel has excellent anti-rust performance and can maintain long-term stability in humid and corrosive environments, thereby extending the service life of the air compressor.
3. Simplified maintenance to reduce the risk of rust: Oil-free air compressors do not require frequent replacement of lubricating oil, reducing the risk of rust caused by lubricating oil leakage or deterioration. At the same time, the maintenance process is relatively simple, reducing the corrosion problem caused by improper maintenance.

Potential Risk of Corrosion of Oil Air Compressor

1. limited effectiveness of rust inhibitors in lubricating oils: Although the lubricating oil in the oil air compressor contains rust inhibitor, it can adhere to the metal surface to form a protective film to prevent the occurrence of rust. However, this protective film is not absolutely reliable, especially in high temperature, high humidity or corrosive environment, the effect of rust inhibitor may be greatly reduced.
2. Rust caused by lubricating oil leakage: During the operation of the oil air compressor, if the lubricating oil leaks, it may adhere to the metal surface and interact with moisture, oxygen, etc., causing rust. In addition, the deterioration of lubricating oil may also produce acidic substances, further aggravating the corrosion process.
3. Improper maintenance increases the risk of rust: The oil air compressor needs to replace the lubricating oil and filter element regularly. If the maintenance is improper or the replacement is not timely, it may cause the performance of the lubricating oil to decrease, thereby increasing the risk of corrosion.
