330HP 250KW air compressor machine

professional air compressor manufacturer,no middleman!

Genuine Original Air End System

Air end is the heart of screw air compressor, it directly in­uences the energy efficiency and noise.
DENAIR air compressor adopts original Germany AERZEN air end or Germany DENAIR air end, advanced SAP rotor
molded lines, Germany steel forging and heat treated process technology for the material of rotors, its efficiency
is 15% higher than nodular cast iron and abrasive process technology for the material of rotors.

Standard Air End,Low Speed Transmission

Every unit of DENAIR air compressor adopts standard superior air end, there will not be high rotation problem.

When choosing the air end, strictly refer to our principle: the best specific power of low rotation speed.

Genuine low rotation speed and high specific power, gets the maximum efficiency of energy-saving and silence.

Unique Cooling Flow Design

Advanced object-oriented design makes the cold and heat exchange more complete.

The gas-oil line design of inner mental tube makes the cooling oil line lubrication achieve higher speed, take o

the air end heat in time and totally avoid the high temperature of air end.

Optimum Design of the System

The technicians optimize the system to largely reduce errors in running, to make the air output more sufficient

and make the energy consumption advanced in the industry

Intelligent Control

The industry leading fully automatic control center for time switch and electric components are all chosen from

world-renowned electric products and bring to you the resulting sense of reliability and convenience in the use

of our air compressors

Air Inlet Valve

The high-quality air inlet valves can make 0 ~ 100% stepless adjustment to the air delivery of compressor

depending on specific demands for terminal air supply, thus reducing the energy consumption. The non-return

valve is disposed in an air inlet valve to prevent backfl­ow of air and oil in case of unexpected halt. Several kinds

of valves can be applied to stationary or portable compressors.
