Two decades of engineering innovation, global supply chain strength, and a relentless commitment to customer success make us the preferred partner for industrial air compression.
Founded in 2004, our team of experienced engineers has refined every aspect of screw air compressor design, from rotor geometry to PLC control systems, ensuring peak performance in every unit.
Our VFD, PM motor, and two-stage compression technologies deliver up to 35% energy savings compared to conventional fixed-speed compressors, reducing your total cost of ownership significantly.
Industry-leading noise reduction engineering ensures our compressors operate at less than 63dB(A) — ideal for noise-sensitive environments including hospitals, laboratories, and offices.
We are a trusted OEM manufacturer for internationally renowned brands, with the engineering flexibility to customize compressor specifications, branding, and configurations to your exact requirements.
Our professional consultants provide complimentary on-site design consultation and energy-saving solutions to optimize your compressed air system and reduce operational costs before you invest.
Every compressor is manufactured under strict ISO quality management systems and carries CE certification, backed by a 1-year full machine warranty and professional after-sales technical support.
At Shanghai Honest Compressor, our R&D commitment is at the core of every product we engineer. Our dedicated team continuously advances rotor profile design, thermal management, and intelligent control systems to push the boundaries of compression efficiency.
The two-stage compression oil injection screw air compressor represents our flagship innovation — combining first-stage and second-stage compression rotors in a single casing with front gear drive, achieving optimal line speed matching for each compression stage while minimizing leakage and noise.
