Advantages come from the excellent performance of CMN air end, embodiment of water lubricated technology
No shaft sealing design, no oil leakage from the air end
Without any lubricate oil, the shaft sealing can’t be using for long time. CMN has developed delicate, contact-less, wear resistant no shaft sealing design to work out the difficulty of sealing. Life time of sealing is called as no shaft sealing design.
Energy saving, air production is 10% more compared with the same power, electricity saved more than 10% directly.
The precondition of the oil-free water lubricated technology is that volumetric efficiency needs to reach above 95%, that is to say, the leakage should be less than 5%. The production technology of CMN oil-free has applied to oil screw air compressor, which improves the efficiency and assures the air leakage less than 4%.
High temperature resistance, the maximum continual temperature of this unit is less than 92℃ at 55℃ ambient temperature.
CMN air leakage is less than 4%, less heat, excellent performance of high temperature resistance.
Less oil content <2PPM
CMN high efficiency air end assures the excellent sealing effect with injecting of a little lubricate oil, oil content <2PPM called micro oil screw air compressor
