High-speed Hair Dryer (SN32F405)

Part No. SN32F405

Hair dryers are a necessity in life. Traditional hair dryers usually rotate at around 20,000 rpm, which makes hair drying slow, noisy, heavy, and not very user-friendly. High-speed hair dryers usually rotate at around 110,000 rpm, which allows hair to be dried quickly without damaging it. They are also smaller, lighter, and quieter.

Main advantages

1. Intelligent constant temperature, Precise temperature control, Real-time monitoring of wind temperature
2. 110,000 rpm high speed brushless motor, High speed, Quick-drying
3. High concentration of deep negative ions, continue to neutralize static electricity, Smooth your hair
4. Multi-stage wind speed and temperature adjustable
5. No noise, natural wind
6. Lock moisture, protect soft and bright hair
