55KW 8BAR 550M3/HR Oil Free Dry Air Compressorsilent oil free air compressor
Dry oil-free screw air compressors are mostly twin-screw air compressors, which means that air is sucked into the rotor tightly. The lubrication and sealing of the rotor are carried out by coating on the surface of the rotor teeth, and the general power is 15~900k.
Product advantages
Intelligent control system
Assembly of large LCD display screen,stick out a mile,convenient operation;
With the compressor needs maintenance or failure,the display will automatically send warning prompt,remind customers timely maintenance or troubleshooting.
Low pressure, high pressure Air end
DHH dry oil-free air compressor adopts the air end special for low pressure and high pressure that developed with unique technology,also adopts the high quality components to ensure the most pure compressed air.
High efficiency oil pump
Using a suitable pump to prevent reverse cycle oil for the smooth operation of the compressor to provide the most suitable operating environment.
Adopting cooling fan inverter
Using the most sophisticated advanced inverter automatically adjusted according to the amount of cooling load, only to run smoothly and achieve optimal energy efficiency.
The latest water separator
Using large capacity of water separator to remove the condensed water from the compressed air,which prolongs the air end working life well and provides a best running environment.
