Application of diesel engine portable screw air compressor


Diesel engine portable compressors are widely used in railroad construction, building construction, shipyard, mining and most of the outdoor operation. Through the cutting edge production technology and intelligent engineering, our compressor offers the best perfomance portable screw compressor




1.World advanced screw compressor with the features of highly efficiency,low maintenance and long lifetime.

2.Microcomputor control system to automatically control the start and top the machine and adjust the air capacity.

3.Conplete protection function with fault alarm and indication

4.Efficient filtering and seperating system.

5.Large oil-after cooler ensures the machines in optimum operation temperature when the ambient temperature is high.

6.Efficient air-cooled enclosed motor.

7.Super low noise.


The Features of the  Diesel Portable Air Compressor



1.Energy Saving - Saving of the diesel is equivalent to one set price of diesel lg air compressor and Lower noise level


2.Air end-large diameter rotor of the portable air compressor, air end connect with diesel engine through coupling and no reduction gear inside, more reliability, the rotate speed is same with the diesel engine's, more longer lifespan


3.Diesel engine-select the diesel engine of CUMMINS brand for this diesel portable air compressor, satisfy the emission requirement of Europe, low oil consumption, after sale service system all over China.


4.Good adaptability-The diesel portable lg air compressor automatically control the air delivery of diesel engine by matching the demand of air consumption, which equal to frequency conversion control in motor power portable lg air compressor

Patented SKY2 Compressors


Designed with a maximum pressure of 40 bar

Rotary: The SKY 2 Screw Engine is a patented rotary with the highest efficiency. Its high pressure ensures its large displacement.

Two-stage compression: its flexible design, which is a world-class patented invention, is compatible to poppet valves.

With the heavy-duty SKF bearing and the direct drive in place, it provides noiseless gearwheels.

With its optimal structure, it provides the most reliable performance.

With a switch design for dual working conditions, users may choose the working conditions of 33 m3 at a pressure of 2.5 MPa, or the working conditions of 25 m3 at a pressure of 3.5 MPa. The switch can be done easily and quickly.


Heavy-duty electric diesel injection engine


Variable fuel injection system: direct fuel injection of high pressure common rail.

It can be equipped with heavy-duty electric diesel injection engines, including Cummins and Yuchai. Based on the loading conditions, oil injection can be electronically and precisely controlled, thus ensuring the best combustion state during the entire operation of an engine. This product features combustion that is more economical with better reliability and stronger dynamic performance.
