Yes. Our motors come with PCB conformal coating for moisture, dust and static resistance. They work stably in 5%–95% RH and dusty purification environments without short circuits.
We support PWM, 0–5V, and 0–10V. Custom start-up speed and control curves are available for smart fans and medical equipment.
Yes, rotation direction can be customized by wiring or control signal. Reversible function is widely used in ventilation and bidirectional airflow devices.
We use high-quality ball bearings for longer life and lower noise. Sleeve bearings are optional for cost-sensitive projects with lower speed requirements.
Our motors use Class B insulation (130℃), withstanding AC500‑600V voltage and insulation resistance ≥10MΩ to ensure safe and reliable use.
The PCB reaches 850℃ flame-retardant level, effectively preventing ignition and spread of fire, meeting safety requirements for home and medical appliances.
