Product Advantage
High-temperature resistant: All the motor components are made of 180℃ high-temperature pure copper wire, which offers higher temperature resistance and is suitable for a wider range of applications.
High suction power: With a static pressure of up to 1000 pa and a ventilation volume of up to 26,000 m³/h, it has greater suction force and can discharge smoke more quickly.
Stable operation: Both during production and before final assembly, dynamic balance tests are conducted to ensure continuous operation without any faults for 20,000 hours.
Low noise: Utilizing the advantages of the external rotor structure, the noise level can be as low as 60 decibels, achieving complete silence.
Good sealing performance: The motor adopts an external rotor structure, ensuring excellent sealing performance. It is more resistant to water, dust and oil.
Aesthetics: Compact design, self-manufactured processing procedures, high-temperature powder coating treatment, attractive appearance
