DC Fans, such as the 4412/2H model, are designed to cool heat-generating devices, helping to maintain safe operating temperatures and to avoid overheating. The 4412/2H is a 120-millimetre diameter fan which can move air at an impressive 1.75 cubic metres per minute (CFM). It promises reliable, long-term performance, and uses dual bal bearing technology to deliver a long service life with reduced noise levels.

Application field

DC Fans are widely used in electronics, where they can help to maintain a safe temperature for a range of systems, from servers to PCs. They are also popular in small-scale industrial applications, such as robotic systems, and in medical equipment. The 4412/2H, with its 120-millimetre size, is often installed in electronics such as computers and workstations.

Working principle

A 4412/2H fan has two sets of fan blades; the impeller\'s outer blades move air axially, while the inner fan blades move air more radially. A motor drives both sets of blades, creating a draft that sucks in air and forces it out through the center of the fan. The motor is usually controlled by an adjustable controller, which permits the user to adjust the fan speed to achieve the desired balance of noise and cooling efficiency.

The 4412/2H fan operates at an impressive 3800RPM, while still maintaining low noise levels of just 39.3 dB(A). This is achieved through the use of dual ball bearings, where both the motor and the fan are operated by the same set of bearings. This design also helps to ensure a long service life, making it an ideal choice for long-term applications.

Conclusion

The 4412/2H is a highly efficient, reliable DC fan, perfect for applications requiring a consistent cooling effect. Its low noise levels and long service life make it an ideal choice for electronics, industrial and medical applications.
