Liutech Portable Air Compressor Products Features
1. Compression Element
As we know, the element whose performance directly effects the operation and life of the machine is a heart of a rotary screw compressor.

The series compressors have the latest evolution of the asymmetrical profile rotary screw element provided by Atlas Copco Group.
The Airtec factory located in Antwerp is well-kwon as the largest compressor manufacturer in the world.
The two rotors with asymmetric profile, which have the same diameter, are mounted on high quality, low wear ball and roller bearings. The high degree of sealing and the fine tolerance level used in the element also guarantees even, in small power ranges:
Greater yield
High efficiency
Long life and high reliability
Constant, durable performance

2. Diesel Motor
The series compressors are powered by a diesel engine from Cummins with high reliability and long life, providing a reliable source of compressed air.
The diesel motor are specially designed for operating in engineering industry, which make sure portable air compressors stably and simply work under 3000 meters height above sea level.

3. Four Phased Fuel Filtration System
A highly efficient fuel filtration system installed on the portable air compressors: post filter, pre-filter and primary filter, secondary filter of water separator, providing the customer with high cleanness fuel and excellent performance.

4. Drive Transmission
The elastic coupling with high performance is of compact structure, simple intervention and long life, contributing to low operating cost.
Advanced gear wheel, provided by Atlas Copco, is particularly designed in accordance with AGM13 as standard, also suitable for heavy and severe duty.
The coupling connecting the element with the electric motor ensures high reliability and efficiency under any operating conditions.

5. Air Control and Adjustment System
The series compressors are equipped with imported unload valve, more efficient and economical than before.
It can perform the ON/OFF regulation or frequency conversion automatic flow regulation and diesel engine speed according to customers' requirements to improve the efficiency of whole machine and achieve energy conservation.

6. Cooler
Careful analysis of the flow of the air, as it is directed through, the principle components, contributes to maintaining the correct thermal balance of all internal parts of the machine, and ensures that the compressed air is distributed at optimum temperature. A correct low operating temperature guarantees dependable long-term operation.
The Air / Oil circuits are cooled by high efficiency aluminium a type cooler blocks, which has been designed with a large surface area for a maximum cooling efficiency.
Coolers blocks have been especially sized to reduce to the maximum temperature of both air and oil fluids for higher performance and expansion of components life time.

7. Air-Oil-Separator
The air quality of an oil lubricated air compressor is reliant on the scavenge system of the oil separator.
Air / Oil separator system of the series portable compressors is designed to provide low residual oil content (≤3 ppm) in the air entering the compressor network.

8. Electronic Controller
The electronic controller installed on the series compressors with high efficiency are specially designed for portable compressor.
The controller permits
Overall system performance status, protection shutdown, malfunction indication etc
Automatic malfunction protection, shutdown and indication:
exhaust temperature of engine, water temperature of engine, exhaust temperature of compressor, fuel level, pressure, working hours.

9. Environmental
LIUTECH's stringent manufacturing standards which follow the ISO 9001 and ISO14001 regulations for quality and environment assurance produce compressors that are made and tested to perform in the most demanding condition.
