FAQ


Q: Are you a factory?
A: Yes, we have our own brand ‘’Fengheng’, we are a factory, and we are OEM/ODM
Q: What are the sizes of your fans?
A: Our fans have sizes between 15mm-254mm, and you can design the fan
Choose the appropriate fan size for the size of the stay.

Q: Do you have a minimum order quantity?
A: Yes, we have different MOQ requirements for different sizes. You can consult us for this. Of course, if you just want a sample test, we apply to provide you with a sample test for free.
Q: How do you currently control the quality?
A: Our company strictly follows the ISO9000-2015 standard production process from raw materials to finished products to ensure the quality of each product.
Q: What do I need to do if I want to develop a new product?
A: You can provide us with your sketches and express your desired product effects or ideas. Our design team will review them, make suggestions, and give you 3D drawings for your reference simulation, and then further complete the mold opening Make.
Q: How long does your mold making time take?
A: The mold opening time cycle of new products is about 30-45 days.
Q: How about your delivery?
A: Our delivery cycle is controlled within 10 days, but if special requirements are involved, the time may be slightly longer.
Q: How do we learn more about fans?
A: Generally, we need to understand the fan size range that you need to know. This is the design output voltage on the control panel, and your requirements for air volume, speed, noise, this piece, or more functional designs: for example: FG signal, PWM temperature speed regulation, and the production of LED lights, waterproof, moisture-proof, etc...

Q:What is a DC axial fan?
A:The DC fan is usually powered by 3v, 5v, 12v, 24v, 36v and 48v. It blows air along the fan axis or parallel to the track of the blade axis. The standard DC axial fan size includes 20mm, 30mm, 40mm, 50mm, 60mm , 70mm, 80mm, 90mm, 92mm, 120mm, 150mm, 175mm, 180mm, 200mm and 220mm


Q:How to choose a DC fan?
When choosing a DC fan, please consider the following points
1. Fan voltage
2. Fan bearing
3. Fan current
4. Fan speed
5. Fan airflow
6. Fan noise
7. Fan life
8. Fan working environment
9. Application of fan products


Q:What is a bearing?
A:Fan bearings include sleeve bearings, hydraulic, ball bearings, sleeve bearing fans have an expected life of 20000-30000 hours, hydraulic bearings 3000 hours, and ball bearings 4-60000 hours.
Q: How is the noise of the fan tested?
A: The noise value of a certain fan logo refers to the number of decibels measured at a distance of 1 meter from the fan inlet when the fan is unobstructed from the front and rear.
Q: What are the sources of fan noise?
A: 1. The noise made by the fan blades cutting wind.
2.The noise made by the bearing when the fan rotates.
3.Small electronic noise when the internal magnetic pole of the fan is switched.
4. Due to air flow, some devices caused by wind in the system
Pieces shake.
5. The box body caused by the vibration generated during the rotation of the fan
Vibrate.

Q: What is the function of using PWM to control the fan?
A: By changing the duty cycle of the input PWM signal, we can control the fan speed within a certain range.
Q: What is a PWM signal?
A: Chinese is: "Pulse Width Modulation". That is, the waveform signal is formed by the control circuit at a fixed frequency "on" and "off" time (this "time" is called the duty cycle).
Fixed frequency (frequency: how many cycles are completed in one second)
Duty cycle (this is also the main parameter of the PWM signal)
Therefore, the sufficient conditions to form a PWM signal: frequency, duty cycle.
