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.

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.

Huada two-stage dry oil-free screw air compressor uses dry oil-free compression to truly achieve 100% oil-free air.The rotor is made of high-quality corrosion-resistant stainless steel materials,high temperature resistance,corrosion resistance,oxidation resistance,and long life.

22kw two stage PM VSD screw compressor using large motor to reduce the unit speed, full load speed in the 2000RPM is a more quiet guarantee. The new air duct structure design, so that the whole air duce pressure difference, the structure is more beautiful.

45kw 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.

55kw double stage compression structure, more energy saving. Compression and high efficiency screw machine is a low pressure ratio, a greater drgree of lower volume leakage to improve energy efficiency. Lower than ordinary screw speed, and the use of of multiple damping springs, so that the unit has a higher stability.

Dobule stage compression structure, more energy saving. The core is the two-level compression of the injection screw air compressor in same power than single-stage compression of the injection screw air compressor and more 12%-23% air volume.
