Kaishan OGWD series 100% Oil-free Water-injected Rotary Screw Air Compressor

Features
◎Super energy saving: Kaishan’s original patent, three-wire meshing technology, overcomes the low viscosity of water and maintains high volumetric efficiency; the machine head is cooled by water spray atomization to ensure that the system is nearly isothermal compression.
◎0 oil content: the main engine is lubricated and sealed by water spray, and the world’s advanced patented sealing system is used between the compression chamber and the bearing chamber to ensure that the entire system is oil-free; the entire series has passed the ISO8573-1:2010 standard of German TUV for compressed air oil content 0 (highest level) certification.
◎High reliability: 100% stainless steel is used to manufacture the main engine, and the main engine parts are made of special stainless steel with excellent wear resistance and corrosion resistance, which is more durable than coating materials and does not require rust prevention and maintenance.
◎Low noise: The single screw has balanced axial and radial forces, and the star wheel rotates freely with the screw under water film lubrication, so the main engine components run smoothly under low load, ensuring low noise and durability.
