oil-free screw air compressor

　　The entire series adopts stainless steel single screw compressors

　　More than 15% energy-saving compared to secondary dry screws

　　More than 36% energy-saving compared to the first level dry screw

　　The oil-free single screw machine meets the energy-saving standards of oil-based machines

　　Avoid frequent and expensive maintenance of dry-type screws

　　All hosts come from water

　　Single screw

　　A screw and two starwheels arranged vertically on both sides form two compression chambers, and each rotation of the screw compresses 12 times.

　　Ultra energy-saving

　　Applying the three line meshing and non equal width tooth technology of Zhengli Precision, and adopting machining technology to overcome the low viscosity of water and maintain high volumetric efficiency, the system is ensured to be approximately isothermal compressed through water spray atomization cooling.

　　Pure oil-free

　　The main engine is lubricated and sealed with water spray, and a sealing system is used between the compression chamber and the bearing chamber to ensure that the entire system is oil-free.

　　High reliability

　　The unit adopts an all stainless steel host, and the host components are made of special stainless steel with excellent wear resistance and corrosion resistance, which is more durable than using coating materials and saves rust prevention maintenance.

　　Low noise

　　The axial and radial forces of the single screw are balanced, and the star wheel rotates freely with the screw under water film lubrication. Therefore, the main components operate smoothly under low load, ensuring low noise and durability.
