1. The fan can run for a long time under a negative pressure of 100 Pa, and has a strong pressure resistance;
2. Motor: The permanent magnet motor and control part are integrated, with a motor efficiency of 91.2%, which is efficient and energy-saving;
3. Speed regulation: Through the 0-10 V signal, the stepless speed regulation of motor can be achieved, with a range of 215 rpm-750 rpm;
4. Voltage withstanding: The motor is designed with wide voltage, which can adapt to the voltage range of 340 V-460 V and run for a long time;
5. Fan blade: It is made of reinforced nylon glass fiber, which has a high impact strength;
6. Outer shell: It is fully plastic, which is corrosion-resistant, rust-free, weather-resistant and anti-aging;
7. Transmission: The direct drive transmission has a high efficiency, and daily maintenance such as belt tensioning maintenance is not required;
8. Butterfly sheet: The opening and closing of butterfly sheet is driven by an electric valve, showing a good sealing effect.
