Product Description

5.5kw 7.5hp Rotary Air Compressor Silent Universal Low Pressure Oil Free Scroll Air Compressor Pump

The oil-free scroll air compression main engine is the latest air compressor developed in recent years. Compared with the traditional air compressor, it has novel structure, small size, light weight, low noise, long service life and stable and continuous gas transmission. It is easy to operate, low maintenance cost and other excellent technical performance. It is praised as "no maintenance air compressor" and "new revolutionary air compressor" in the industry. It is the ideal model for air compressors below 50HP.


Working principle of scroll compressor

The oil-free scroll-type air compressor is formed by the mutual meshing of the moving and stationary scrolls of two double-function equation lines. During the process of suction, compression and exhaust, the static plate is fixed on the frame, and the moving plate is driven by the eccentric shaft and is restricted by the anti-rotation mechanism, and rotates around the center of the base of the static disk to make a plane with a small radius. The gas is sucked into the periphery of the stationary disk through the air filter. As the eccentric shaft rotates, the gas is gradually compressed in a plurality of crescent-shaped compression chambers combined with the dynamic and static disk phasing, and then continuously discharged from the axial holes of the central portion of the stationary disk.
