Diesel Portable Screw Air Compressor adopts 0-100% infinitely variable control of Capacity to realize optimal energy saving effect.

• Fully realizes "Convex-Convex" engagement to assist in the formation of hydrodynamic lubrication film, reducing horizontal leakage passing the contact zone and improving compressor efficiency while enhancing rotor processing and testing properties.
• Utilizes "large rotor, large bearing and low speed method" design, resulting in 30-50% lower revolving speed compared to other brands. This reduces noise, vibration, and exhaust temperature while improving rotor rigidity, increasing service life, and reducing sensitivity to contaminants and oil carbide.
• Power range of 4~355KW, with 18.5~250KW models suitable for compressors without direct-coupled gearbox. 200KW and 250KW models are compatible with Level 4 direct-coupled motors at speeds as low as 1480 rpm.
• Fully conforms to and exceeds requirements in GB19153-2003 Limited Values of Energy Efficiency and Evaluating Values of Energy Conservation of Capacity Air Compressors.
