Why Choose CMN Scroll Compressor
CMN oil-free scroll air compressor VS traditional belt type scroll air compressor
| CMN Scroll Compressor | Traditional Belt Scroll Air Compressor | |
| Layout comparison | The overall design is simple, the layout is reasonable, and it is convenient for inspection and maintenance. | Traditional design with chaotic layout. |
| Water outlet design comparison | The CMN spout is designed at the bottom and is equipped with rollers for easy movement. | The water outlet is designed on the top. |
| CMN Scroll Compressor | Traditional Belt Scroll Air Compressor | |
| Air end | CMN patented technology, square design, easy to reach 1.25Mpa pressure. | The air end is traditionally designed, and the maximum pressure can only reach 1.0Mpa.达到1.0Mpa。 |
| Motor | The most energy-saving permanent magnet motor is adopted, and the efficiency reaches more than 91%. | Using ordinary motors, the efficiency is low, only 84%. |
| Control panel | The four-line liquid crystal display control screen is used to display the operating pressure in real time, as well as various early warnings, alarms and maintenance prompts. | A control panel in the form of a semiconductor light-emitting digital tube is adopted. Only pressure can be displayed, and other displays can only rely on codes. |
| CMN Scroll Compressor | Traditional Belt Scroll Air Compressor | |
| Comparison of connection methods | CMN adopts the method of direct connection between the air end and the motor, without belt, no belt wear, no need to adjust and replace the belt, and the power transmission efficiency is high. | Use belt drive, low efficiency. The belt needs to be adjusted or replaced due to belt wear. |
| Motor start mode | Permanent magnet drive, easy and smooth slow start, no start shock, the starting current is the same as the working current. | Using direct start, the impact force is large, the instantaneous current of starting is 5 times of the working current, which affects the voltage of the grid, and the force on the shaft is large, which affects the service life |
