Does the oil-free air compressor need refueling?

Oil-free air compressors do not need to be refueled. The water-lubricated air compressors produced by Granklin Group are 100% free of oil.

However, our atmosphere contains certain oil and gas, particulate matter, etc., so in the post-equipment processing process, we still need precision filters and other post-equipment.

For water-lubricated air compressors, the machine is like its name, and there is no lubricating oil inside the air compressor head to participate in the work. It is all sealed by water for lubrication and heat dissipation.

Therefore, oil-free air compressor can be assured to choose water lubricated air compressor.
