The difference between oil-injected screw and oil-free screw air compressor

Q: What is the difference between oil-injected screw and oil-free screw air compressor?

Answer: As the name implies, when the air compressor head of the oil-injected screw air compressor is working, the inside of the head is lubricated and cooled by lubricating oil. Therefore, the oil content in the compressed gas is relatively large, and the loss of the post-processing equipment is completely different from that of the oil-free screw air compressor.

Oil-free screw air compressor such as granklin group's water lubricated air compressor, in the work of the air compressor is not a drop of lubricating oil to participate in, the use of water as a lubricating substance, and to achieve isothermal compression.

The different working methods determine the difference in production cost between the two. The oil-free air compressor chooses stainless steel as the air compressor head. From the root cause, the oil-free screw air compressor is preferred in the middle and high-end manufacturing and processing industry.

The gas requirement is not high user selection oil injection screw air compressor is more appropriate.
