K Series Oil Injected Rotary Screw Air Compressor
The oil injected rotary screw air compressor is a type of positive displacement compressor with superior and reliable performance, low vibration, low noise, high efficiency, few wearing parts, easy operation and maintenance. It adopts a high-efficiency motor to drive the rotary screw airend rotating for air compression. The precise matching between the male and female rotors and between the rotors and the airend housing reduces internal air leakage and improves efficiency. Only the rotors mesh with each other, without the reciprocating motion of piston cylinder, which reduces the vibration and noise level. Relying on the pressure difference generated by itself, it continuously injects lubricating oil into the compression chamber and bearings, simplifying the complex mechanical structure. The injected lubricating oil forms an oil film between the rotors, increasing the air tightness of the compression, improving efficiency and reducing high-frequency noise. The compressed air/oil mixture discharged from the airend enters the aftercooler for cooling after separation, reducing the temperature and improving the quality of the compressed air.
Product Features
State-of-the-art Compressor Airend

Optimal Energy efficiency and outstanding reliability is achieved from patented design third generation non-symmetric robust rotors, superior bearings and oil seal that help the compressor airend to operate with good dynamic balance, low vibration, low rotation speed and low noise level.



Energy Saving Electric Motor


T.E.F.C Highly efficient, totally enclosed fan-cooled (T.E.F.C.),IP55, class F electric motor can achieve high efficiency of 95.2% that brings an unprecedented level of energy saving. High quality high speed bearings from “SKF”are fitted for continuous trouble-free operation.


High Efficiency Air Cooler System
Big capacity models adopt double cooling fan design. The first cooling fan starts up with the compressor and the second one starts up only when the operating temperature exceeds 80℃ and it stops when goes back below 70℃ in order to save energy.
Intelligent Touch Screen Control Panel
The simple-to-use automatic electric control panel continuously monitors and displays overall system performance status with pro-active service indications, alarms for malfunctions and safety shutdowns. Advanced sequence control for multi-units installation and remote control as option.
