1.7 m power cord
Thickened and resistant to high temperature
18000rpm high-speed motor: input rated voltage frequency, measure strong windshield
The rotating speed of the lower wind blade when working in the position of the shield and the hairdryer is tightly attached to the harmonic position.
Read the speed on the vibration tachometer.
12m/s large air volume dry: input rated voltage frequency, outlet distance anemometer
10cm maintains 1s, reads the wind speed value from the anemometer, and the strong windshield is greater than 12m/s.
Noise test: at rated voltage, ambient noise below 35 decibels, the prototype is strong
When the windshield is working, the motor position is 30 cm from the noise meter, and the horizontal direction is 30 cm. And the average noise size in the vertical direction ≤ 80dB.
