DC 70mm Blower Fans 5V 12V 24V 75mm x 15mm 7515 2.75 Inch Brushless Axial Blower Fan

Rx SOLUTIONS cooling fans and blowers provide cooling solutions to your system thermal problems. The need for forced-air cooling by using an AC or DC axial fan or blower should be determined at an early stage in the system design. It is important that the design plans for good airflow to heat-generating components and allows adequate space and power for the cooling fan or blower.

1. What is a DC/AC Axial Fan?

An AC/DC 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 AC/DC fan?

To choose a AC/DC 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 50000hours 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 50°C+/-5°C. Units are monitored and tested on daily basis. Failed units will be analyzed and corrective actions taken where necessary.
