Air Compressor SystemsOil Free Screw Compressor SDS-U Series Two-Stage 90-450kW

New Air-End

The essence of our original technologies behind abundant track record, is concentrated into profiling Air Block. The 3-D fluid analysis that makes full use of an advanced CFD (Computational Fluid Dynamics) technology simulates to assist in optimizing shapes of air flow path, inlet, outlet and rotor.

3-D Screw Rotor Compensating Thermal Deformation

A 3-D screw rotor (patented) that compensates for the thermal deformation distribution from the difference in air temperature between the inlet and outlet sides. The rotor, for which the high precision machining technology is applied, has a surface coated with a new resin material (patented), which gives the rotor a high level of durability.

Long-Life Bearings

In addition to high quality materials and high precision technology used for the bearings, advanced analysis technologies and lubricating theory are applied to select the type of lubricant, cleanliness, spray nozzle shape and other items affecting the bearings. Every effort is made to give the bearings a longer life.

Highly Reliable Shaft Seal

Through the use of a wear-resistant floating seal, air leakage can be sealed for a long time. High quality thread seals are also employed for bearings, providing double prevention against oil mist entering the compression chamber.
