DC Fans have been a popular choice in commercial and industrial applications for their efficiency and a wide array of speeds, control options, and performance ratings. The 9GA0912F402 is one of the more popular DC fans available for use in these applications and this article will provide an overview of its application field and working principle.

The 9GA0912F402 DC fan is designed for use in commercial and industrial applications that require reliable cooling air flow. It is especially suited for use in applications that require high speed operation over a wide range of temperatures. Its speed can be adjusted in both clockwise and counterclockwise directions, allowing users to maximize air flow and cooling performance for the application. It is also important to note that the 9GA0912F402 provides a low-cost solution for applications requiring efficient cooling with air flow ratings up to 1250 CFM (cubic feet per minute).

The 9GA0912F402 is a heavy-duty, single-phase DC fan that operates at 12 volts and draws a maximum of 2.25 amps. This model is capable of providing up to an impressive 1250 CFM of cooling air flow at speeds of up to 2000 RPM. It is also capable of providing efficient cooling with a maximum static pressure of up to 0.40 inches of water, allowing users to maximize their cooling performance.

The working principle of the 9GA0912F402 DC fan utilizes a permanent magnet type of motor working as a rotor, and a stator comprising of four poles with coils wound around them. When energized by AC voltage, the coils generate an electromotive force, which causes the rotor to turn. This rotation motion is used to create a centrifugal force, forcing air through the fan blades while producing the fan’s cooling air flow.

The 9GA0912F402 DC fan is highly reliable and features a MTBF of up to 90000 hrs. This DC fan also features an auto restart safety feature which is designed to restart the fan after a unexpected power failure or surge. This unique safety feature helps to prevent potential damage to the fan and the application in which it is installed.

In conclusion, the 9GA0912F402 DC fan is an excellent choice for commercial and industrial applications that require reliable cooling air flow with a wide range of speed and performance ratings. This efficient and dependable DC fan offers users a low-cost solution for cooling, with an auto-restart safety feature and impressive performance ratings.
