It has functions such as wind and sand prevention.Quick start, stable operation, loud sound source, strong penetration, and wide sound coverageThe surface is sprayed with anti rust paint, which effectively prevents corrosion and has a longer lifespan.Wide heat dissipation and sound amplification port, combining heat dissipation and sound amplification, fast heat dissipation and high ventilation efficiencyThe high-speed motor drives the bidirectional wind spiral to generate continuous alarm sound, and the multi wing impeller adopts dynamic balance calibration with strict wind mechanics technology, which plays a more powerful decibel effect in converting wind energy into sound energyAdopting high-frequency motor speed rotation, with a speed of ≥ 1000x/MIN, stable operation, copper core coil drive, more efficient and powerful performance
