    Mr.Kerry Robinson from Australia
    today I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption.

Product Description

Two Stage High Pressure 1200Cfm 365Psi Diesel Portable Air Screw compressor

Shanghai Rotorcomp's fully implemented Quality Management and Environmental Management systems in the design and manufacturing of these units fulfill the requirements of ISO 9001 and ISO 14001.
The range has also been tested / given the certificate tested according to ISO 1217.
The most efficient wheeled Diesel compressor, Deutz, Ctapillar, Cummins diesel engine, less10-15% diesel consumption than the traditional model. More flexible in various working conditions for mining, road construction. Sand blasting.


Advantages of Diesel Portable Screw Compressor:

1. Two-stage screw block is patented;
2. Designed for a maximum pressure of 40 bar;
3. Two-stage compression; Deutz, Cummins, and Yuchai World well-known engines
4. SKF bearings, direct drive, no noise gears;


Application of Diesel Portable Screw Compressor:

Shanghai rotorcomp diesel Portable/Mobile screw air compressor is widely used in mines, water conservancy, transportation, shipbuilding, urban construction, energy, industry and other industries.

Diesel Portable Compressor Features:

Diesel portable screw air compressor is widely applied in the industries, such as, road, railway, mine, water conservancy, shipbuilding, urban construction, energy and war industry, etc.

Shanghai Rotorcomp diesel portable screw air compressor is efficient and reliable, with complete varieties. Discharge quantity covers 33m3/min and the discharge pressure is up to 3.5MPa at maximum.

Our advantages:
1,A high-efficiency cooling system
ensures the compressor operates in the optimum operating mode. There are independent oil, water and air cooling systems. Equipped with a fan of a larger diameter, adapted for a cold and hot climate.
2,Triple filtration of air
The patented cyclone air pre-filter, which filters more than 90% of dust and impurities, increases the service life and the replacement of the air filter by 5 times. The cyclone air filter filters residual dust and protects the compressor, the filter cartridge allows safe maintenance of the air filter without stopping the compressor. This system provides continuous operation in desert conditions or large dustiness.


3,Low temperature starting system (option)
The water pump pumps the coolant from the engine into the heat exchanger. The fuel pump pumps fuel from the tank into the combustion chamber, which ignites. At the same time, heat transfer takes place continuously, which increases the temperature of the coolant and oil, as well as the temperature of the compressor itself. This ensures the start of the diesel engine in the frost or in the highlands.


4,Additional cooler (option)
Provides a compressed air temperature at the outlet of 15 degrees less than the ambient temperature.


Triple oil cooling system from compressed air
Reduces the oil content in the oil separator with unstable oil supply. Always saves the amount of oil in the exhaust compressed air no more than 3 ppm. Clean air is necessary for the safe operation of equipment in which compressed air is used.


Microprocessor control system
The simple and convenient interface of the microprocessor control system allows you to monitor the speed during operation, compressed air pressure, oil pressure, outlet air temperature, coolant temperature, fuel level and other parameters. Has the functions of self-diagnosis, alarm and stop. Simple management ensures safe operation without the participation of personnel. An additional option is a remote network monitoring system that allows monitoring the operation of compressors remotely.
