Low Pressure Screw Air Compressor

Low Pressure Air Compressor Advantages:

  • It will cause a terrible waste of electric power if choose a routine 7bar air compressor when the maximum working pressure is 2 to 5bar. DENAIR low pressure screw air compressor can enlarge the air delivery under the same motor power to help you save 20% to 50% electric power.
  • State-of-the-art screw element, original Germany DENAIR air end, advanced SAP profile design, superior Sweden SKF element bearings.
  • Adopts world-renowned components, such as Schneider electronics from France, Danfoss pressure sensor from Denmark, etc. contribute to guarantee the compressor longer service life.
  • Conform to CE, ISO9001 and energy saving certification, etc.
  • Designed especially for textile, cement and glass industry, etc.
