Kaishan JN Series Two-stage Compression Screw Air Compressor

The Kaishan compressor utilizes a two-stage compression main engine, featuring two sets of SKY screw rotors in varying sizes. This design achieves optimal pressure distribution and reduces the compression ratio for each stage, resulting in exceptional efficiency and longevity. By adopting a low compression ratio, this system offers two key benefits: 1) minimized internal leakage that significantly boosts volumetric efficiency, and 2) reduced bearing stress, enhancing bearing longevity and extending the lifespan of the main engine.
A standout feature of the Kaishan compressor is its world-leading "T" patent molded rotor lines, developed by Dr. Tang Yan, a Global Experts Recruitment Program recipient. These rotor lines deliver industry-leading efficiency, offering 5-15% savings compared to conventional designs. Additional innovations in product detailing, system optimization, and high-end configurations further improve efficiency by 5-8% over competing brands.
The JN series Kaishan compressor incorporates cutting-edge air inlet adjustment modules, cooling flow-field design, oil-air separation technology, and highly-efficient motors complemented by intelligent automation control systems. These innovations provide tangible energy savings, delivering consistent cost-reduction benefits to customers. When you choose Kaishan’s advanced two-stage compression technology, you're investing in reliability, efficiency, and superior performance.
