Why Oil Free
Each cubic meters of inlet air, oil-injected system, will carry additional 200 million dust particles and 0.03mg/m3 oil molecules after compression
The oil residues in compressed air cannot be removed completely and will remain even with an oil filter installed
There will be mechanical failure, painting peeling off or perforation due to oil molecules entering into the system; this may even bring harm to human in food and medical industries application
Oil-free compressors with Class 0 certified are required for many industries, especially for food and medical industries
There are many industries and applications with strict laws and regulations regarding oil contamination; oil-free air compressor is more and more widely used to prevent severe consequence due to failure of filtering equipment

Structural Composition
The orbiting scroll rotated in the sequence as shown in the figure:
A. The volume of crescent-shaped compression chamber gradually becomes smaller
B. The compressed air is discharged from the air outlet in the middle
The advanced compression technology ensures continuous and stable suction, compression and discharging process
Compact structure of Oil-Free scroll uses less components and consumables than screw compressor
Simple structural design and framework significantly reduce the possibility of breakdown due to failure on equipment and component
Modular design for more compact structure
Simple structure, easy to mount/dismount, free of maintenance
