Motor quality

Pay attention to the motor with double ball bearings when purchasing. It has a long life and low noise. In addition, it is necessary to choose an all-metal spray wind wheel, which is durable, stable, and conducive to the separation of oil smoke. When purchasing, press the motor start switch repeatedly to compare the running sound after the motor is started and turned off. The smaller the noise, the better.
Exhaust efficiency
