Two stage compression screw air compressor reduces the compression ratio per level,reducing internal leakage and increase the volumetric efficiency,reduces the bearing load,improve the working life of the host.Two stage compression instead of single stage compression,nearly a 15% increase in displacement,can realize a 15% more energy saving effect.

Single stage permanent magnet screw air compressor uses high-strength NdFeB (neodymium iron boron) magnetic steel,high magnetic energy product and coercivity of NdFeB magnetic steel,make rare-earth permanent magnet motor have small size,light weight,high efficient,good character etc,a series of advantages.

75kw two-stage screw air compressor incorporates Huada's nearly 30 years of screw compressor research and development and production technology,centered on the world's highest level of displacement,and surpasses the global market demand.It is the highest performance and highest quality air compressor.

Widely used in industrial fields,such as various pneumatic tools,instrument control,printing,paper,petrochemical,electronics,automobile manufacturing,rubber tire manufacturing,woodworking machinery,rice processing,furniture manufacturing,garment processing,nitrogen production,and air separation etc.
