Why Must Compressed Air in an Oil-Air Lubrication System Be Dry?
Release time:
2022-11-01

Clean and dry compressed air is essential for the stable operation of an oil-air lubrication system.
If the compressed air contains moisture, water can damage the oil-air mixture and reduce lubrication performance. In serious cases, excessive moisture may even cause lubrication failure, leading to increased equipment wear and possible bearing damage.
Moisture in compressed air can also create additional problems such as:
- Oil film instability
- Corrosion of components
- Reduced lubrication efficiency
- Pipeline contamination
- Shortened equipment service life
To ensure reliable system performance, the compressed air supplied to the oil-air lubrication system should be clean, dry, and free of water.
When the moisture content in the air supply is high, it is recommended to install air drying and water separation equipment before the compressed air enters the lubrication system. This helps maintain stable lubrication conditions and protects the system’s precision components.
