DC (Direct Current) Fans are known for their ability to move air quickly and efficiently, particularly in confined spaces. The 9GA0812S161 DC Fan is no exception. With its small size, light weight and high efficiency, it provides an excellent solution for cooling applications. This article will explore the 9GA0812S161 DC Fan’s application field and working principle.

Application Field and Environmental Requirements

The 9GA0812S161 DC Fan is capable of providing cooling solutions in many different applications, such as aircraft, automobiles, electrical and electronic equipment, and other industrial devices. This fan’s optimal environmental requirements include ambient temperatures of up to 85℃, relative humidity between 40 and 90 percent, and an operating altitude of up to 10,000 feet.

The 9GA0812S161 is cost-effective due to its ease of installation and long service life. It can also be used in conditions with strong vibrations or vibrations due to high-frequency noise, making it more reliable and durable compared to other fans. Furthermore, some models can be used in airtight and dust-proof environments.

Working Principle

The 9GA0812S161 DC Fan operates on the principle of the rotation of two sets of curved vanes inside a cylindrical chamber. These vanes draw in air from the front of the fan and direct it out via circular openings at the back. The electric motor drives this rotation via a series of interconnected rods and gears. The speed of the fan can be modified or even stopped altogether, depending on the application.

The 9GA0812S161 DC fan has four sets of speed adjustment option: High Speed, Medium Speed, Low Speed, and Zero Speed. When the speed is adjusted to Zero, the fan also acts as a blower in suction mode. This makes the fan extremely versatile and can be used for both cooling and suction in different operating conditions.

Technical Specifications

The 9GA0812S161 DC fan measures 8 x 8 x 1. 5 inches, which makes it perfect for installation in tight spaces. It has an airflow range of 32.1 CFM to 65 CFM, a maximum static pressure of 0.24 in H2O, and an input voltage from 4.5 to 12 volts DC. The fan also comes with four mounting screws and an optional mounting bracket. The noise level is approximately 41.3 dB(A), though this varies based on the speed option that is selected.

Conclusion

The 9GA0812S161 DC fan is a reliable and highly efficient cooling solution for any application or environment. Its small size and light weight make it perfect for confined spaces, while its high efficiency and adjustable speed option provide versatility. Whether you need to cool an aircraft, automobile, or industrial device, the 9GA0812S161 DC fan is the ideal choice.
