What is oil-free screw air compressor?

In the industrial field that pursues high-quality compressed air, oil-free screw air compressors have gradually become the preferred solution. Compared with traditional oil compressors, oil-free screw air compressors are designed to avoid contact between lubricating oil and compressed air, thereby ensuring the purity of the output air.

Are oil-free screw compressors environmentally friendly?

Environmentally FriendlySince there is no oil used in the system, oil-free screw compressors are more environmentally friendly compared to traditional oil-lubricated compressors. There is no need to dispose of used oil, and the risk of environmental contamination is minimized.

What is an oil-free air compressor?

This equipment typically has no mechanical contact inside the compression chamber, or it uses an alternate material like water or Teflon coating to protect the internal mechanisms without depending on oil lubrication. Oil-free air compressors can provide air purity, environmental benefits and significant cost savings for manufacturers.

What is the best oil-free air compressor?

A best oil-free air compressor will be one that not only meets ISO 8573-1 Class 0 standards but also offers high efficiency, durability, and low operating costs.

Are oil-free compressors a good investment?

Outstanding reliability, low maintenance and operating costs make oil-free compressors a sound investment. WISAIR’s water injected screw offers the most innovative oil free technology and improved energy efficiency thanks to the superior cooling capability of water. Removing the wasted energy that heat represents gives more air per kW of power.

How do oil-free screw compressors work?

Oil-free screw compressors operate using the same basic principles as conventional rotary screw compressors, but with a key difference: they do not use oil for lubrication. Instead, water-injected systems or special oil-free materials are used to create a reliable seal between the rotors.
