Oil-free screw air compressor

Oil-free air compressors do not use oil when it comes to compressed air. In other types of compressors, oil is injected to seal rotors, offer lubrication or provide cooling. With oil-free screw compressors, precision is used to create an oil-free option of the highest quality.


Committed to Manufacturing Solutions

Oil-free water-lubricated screw air compressors are widely used in industries requiring high-quality air sources such as medicine, food, electronics, chemicals, and packaging. Pure compressed air is a necessary measure to ensure process and product quality. You can safely and safely Produce your high-end products efficiently.
The lubrication system of the oil-free screw air compressor is a separate oil supply circulation unit. The compression chamber and the bearing are tightly separated by a high-performance mechanical seal assembly. The lubricating oil can only flow in its closed area and cannot enter the compression area. The compression chamber contains pure air without water, and after a little post-treatment of water and dust removal, pure compressed air can be obtained.
7 advantages of HUAYAN HYW series oil-free and water-lubricated screw compressors:
· 7-inch large touch screen intelligent controller, powerful control and communication functions.
· Adopt the original water-lubricated screw main engine from the Demon Technology Research and Development Center.
· The screw host adopts three-wire meshing and non-equal-width tooth technology, and the meshing pair is in contact with water film, without wear and tear, and the balance of force is good
· The screw host, pipelines and parts are all made of corrosion-resistant special stainless steel materials.
Adopt SKF bearings and independent internal air sealing technology to ensure that the lubricating water does not come into contact with the bearings and maintain the service life of the bearings
· Unique water filtration and lubrication system to ensure good lubrication, sealing, noise reduction and cooling.
· Pure oil-free, oil-free compression system, low noise, super energy-saving.
