2. Steady Flow: Generally, oil free compressor using the latest pressure device, can ensure the output air constant current voltage. When oil-free machines are used in the laboratory, it can improve the precision of some experimental instruments.
3. Operation Easily: Eliminating the problem of exchange and add the lubricating oil, simplifying the use step of air compressor, extending maintenance cycle of air compressor, it makes operation more simple.
4. Low Noise: Generally, the oil-free compressor is silent oil free compressor, noise is very small. It will not affect the surrounding environment, and be beneficial to work for the operators. 
5. Saving Energy: If you use oil-free air compressor to provide the compressed air, it will not reduce motor load greatly due to pressure loss from oil removal equipment, and to achieve energy efficiency.
