I. Product Performance & Technical Parameters

Q1: What are the core advantages of Brushless Centrifugal Fans compared to brushed centrifugal fans?

A1: The core advantages are mainly reflected in four aspects: 1. Longer service life: No carbon brush wear, MTBF (mean time between failures) can reach 50,000-100,000 hours, which is 2-3 times that of brushed fans; 2. Higher stability: No spark generation during operation, lower electromagnetic interference (EMC compliance is easier), suitable for precision electronic equipment; 3. Energy saving and efficiency: The brushless motor has higher conversion efficiency, and the power consumption is 15%-30% lower than that of brushed fans under the same air volume and pressure; 4. Low noise: The operation is smoother, and the noise is 3-5 dB lower than that of brushed fans of the same specification.

Q2: What factors will affect the air volume and static pressure of Brushless Centrifugal Fans?

A2: The main influencing factors include: 1. Speed: Higher speed usually means larger air volume and higher static pressure (subject to motor power limits); 2. Fan blade design: The shape, number of blades, and angle of the centrifugal fan blades directly affect air flow efficiency; 3. Inlet and outlet resistance: The air duct design of the equipment, the type of heat dissipation fins, and the degree of blockage will increase the resistance, thereby reducing the actual air volume and static pressure; 4. Operating voltage: Fluctuations in the rated voltage will cause changes in speed, which in turn affect air volume and pressure; 5. Ambient temperature: High-temperature environments will reduce motor efficiency and slightly attenuate air volume.

Q3: Can Brushless Centrifugal Fans be customized with multi-speed adjustment functions? What are the common control methods?

A3: Yes, multi-speed adjustment is a common customized function for Brushless Centrifugal Fans. Common control methods include: 1. PWM speed regulation: Adjust the speed by changing the duty cycle of the PWM signal, with high adjustment precision (adjustment range 10%-100%), suitable for intelligent equipment that needs real-time speed adjustment according to temperature; 2. Voltage speed regulation: Adjust the speed by changing the input voltage (within the rated voltage range), simple circuit design, suitable for simple speed regulation scenarios; 3. Resistance speed regulation: Adjust the speed through external resistors, low cost but low precision, suitable for low-demand occasions; 4. Signal feedback speed regulation: Equipped with FG speed signal output, real-time monitoring of speed, and automatic adjustment through the host control system to ensure stable operation.

Q4: What is the applicable operating temperature range of ordinary Brushless Centrifugal Fans? Can they be customized for high-temperature or low-temperature environments?

A4: The operating temperature range of ordinary Brushless Centrifugal Fans is -20℃ ~ 80℃, which is suitable for most indoor and general industrial environments. For special temperature scenarios: 1. High-temperature customization: By using high-temperature resistant materials (such as high-temperature resistant enameled wire, ceramic bearings) and optimizing the motor structure, the operating temperature can be increased to -30℃ ~ 120℃, suitable for high-temperature industrial furnaces, new energy vehicle battery packs and other occasions; 2. Low-temperature customization: By optimizing the lubricating oil (using low-temperature resistant grease) and improving the motor startup performance, it can work stably at -40℃ ~ 60℃, suitable for outdoor low-temperature equipment in cold regions.
