FAQ
Q1: Is Wonsmart a manufacturer or a trading company?
A: Wonsmart is a professional manufacturer specializing in BLDC centrifugal blowers and motors. We have our own production facility in Ningbo, China, with automated production and testing equipment to ensure stable quality and reliable performance.
Q2: What is the MOQ for Wonsmart blowers?
A: Our standard MOQ is 1 piece. Customers can purchase samples for testing and evaluation before placing larger production orders.
Q3: Do I need a driver for the Wonsmart blower?
A: Most Wonsmart BLDC blowers require a matched external driver to operate. Depending on the model, speed can be controlled by PWM, analog voltage, or a potentiometer. Some models have a built-in driver and can be connected directly to a DC power supply.
Q4: How can I choose the right Wonsmart blower for my application?
A: Please provide your required airflow, air pressure, voltage, installation space, noise requirement, and application. Our technical team can recommend the most suitable blower and driver combination according to your needs.
Q5: Can Wonsmart provide customized solutions?
A: Yes. Wonsmart supports customized solutions, including special performance requirements, voltage, wiring length, connectors, driver functions, and other project-specific modifications. Please contact us with your detailed requirements for evaluation.
The centrifugal fan uses the centrifugal power supplied from the rotation of impellers to increase the kinetic energy of air/gases. When the impellers rotate, the gas particles near the impellers are thrown off from the impellers, then move into the fan casing. As a result, the kinetic energy of gas is measured as pressure because of the system resistance offered by the casing and duct. The gas is then guided to the exit via outlet ducts. After the gas is thrown-off, the gas pressure in the middle region of the impellers decreases. The gas from the impeller eye rushes in to normalize this. This cycle repeats and therefore the gas can be continuously transferred.
