Screw compressor-is a rotary volume compressor, in which two rotors with helical gear meshing, so that the size of the two rotors from the size small, thus compressed and discharge gas. Screw compression components in screw air compressor, using the latest numerical control grinder internal manufacture, and in line with laser technology, to ensure the manufacturing tolerance incomparable. Its reliability and performance can ensure that compressor operating costs in the life of the extremely low. Adjust compressor, integrated compressor and desiccant series are L LLS series compressor in the new products.

　　Velocity compressor-is a rotary type compressor in which the blades that rotate at high speed accelerate the flow of gas through it, converting speed into pressure. This conversion occurs partly on rotating blades and partly on fixed diffuser or backflow baffle.

　　Centrifugal compressor-A speed compressor in which one or more rotating impellers(blades usually)
