250kw electric stationary air cooled mining sand blasting industrial twin rotor rotary screw type air compressor

• SKF bearing match with high efficiency screw air end,make sure long service time.
• Single stage air compression design,stable air supply.
• Inlet sound attenuation design,build a low noise working environment to user.
• 1-2 years warranty period for whole machine,5 years for air end.

1.Double Screw air end is the core of screw air compressor,its performance directly influence the economy and use costs of the whole machine.

2.Dream compressor adopts the air end original from Europe. Advanced patent SAP shape of screw gear, the most superior screw line speed and compression efficiency, decrease the shake of the whole machine to the fullest extent, and prolong the life of moving parts effectively.

3.The compressor is matched with high-precision SKF bearing. The precise and even bite clearance ensures leak tightness, making sure the compressor become less power dissipation and lower energy consumption under the same working conditions, and achieve goals as following:a.Large air capacity,b.Higher efficiency,c.More stability and reliable,d.Longer service life.

4.High quality air end and bearing contribute to high stability of compressor under changeable conditions.Make the compressor adapts to the changeable of loading and prolong the service life of rotors:a.Low running speed decreases the abrasion of bearing,b.Low running temperature letdown the load of bearing.c.High precision bearing prolongs the service life.

5.DM series compressor combines the electric motor,gear case and air end.Such design makes the air end and electric motor be permanently centered.

6.High efficiency and full closed electric motor(IP54).
