1. What is a DC Axial blower Fan?

An DC blower fan is usually powered by 3v, 5v, 12v, 24v, 36v and 48v. It blows air along the axis of the fan, or parallel to the track of the blade axis. Standard DC Axial fan sizes include 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 92mm,120mm, 150mm, and 200mm.

2. How to choose a DC blower fan?

To choose a DC blower  fan, you should consider the points below
a. fan voltage
b. fan current
c. fan speed
d. fan airflow
e. fan noise
f. fan lifespan

3. What is a bearing?

Fan bearing includes Sleeve Bearing and Ball Bearing, life expectancy of sleeve bearing fan is 30000hours, while ball bearing is 60000hours or more.

4. How do we carry out quality control?

Usually, there are two ways to monitor reliability during the manufacturing process.
a. Early Life Test
This is used as a mean of process control aimed at identifying any latent manufacturing problems and determining the
effectiveness of burn-in. Every day, 5 samples will be picked up randomly from one of the production lines for burn in at 50°C+/-5°C for 24 hours.
b. On-going Reliability Demonstration
This is a longer-term program aimed at providing data on continuous basis to demonstrate the reliability of product. 10 units per month are randomly collected from one of the production lines for burn-in for 168 hours at 0°C+/-5°C. Units are monitored and tested on daily basis. Failed units will be analyzed and corrective actions taken where necessary.

5. What can I do if we can not find the suitable fan model in the fan list?
