3214J/39NR

DC fans, or direct current fans, are widely used in air cooling applications. Unlike traditional air cooling fans, they rely on the movement of DC electric current to generate wind. The 3214J/39NR is one such DC fan that is highly reliable and efficient in both performance and cost. This article will discuss the application field and working principle of the 3214J/39NR DC fan.

Application field

The 3214J/39NR DC fan is designed for use in a variety of industrial and commercial applications. It is designed to be extremely energy efficient, with maximum output of up to 4800 m³/h, making it suitable for cooling both office and industrial benchmark machines and equipment. The fan can be used in both indoor and outdoor locations, such as cooling high temperature areas and cooling hard-to-reach spots.

The fan has been designed with an innovative air channeling system, allowing for efficient air distribution with no areas of static pressure. This ensures that no hot spots are left in the airflow, and that the air is evenly spread over the entire range of the area. The fan also utilizes an advanced low-noise design, making it highly suitable for airports, hospitals, shopping malls, public transportation, and other noise-sensitive environments.

Working Principle

The 3214J/39NR DC fan utilizes a brushless DC motor which works on a magnetic field and a rotating impeller to increase air flow. The DC fan operates on an alternating current, typically in the range of 24 – 48 volts. This creates a rotating magnetic field in the stator, which interacts with the motor\'s permanent magnets to create a rotational force. The resulting rotation of the impeller then causes an increase in the air flow.

The DC fan also utilizes a series of blades to generate lift, allowing the fan to draw in air from all directions. This ensures that cold air is distributed evenly and maximizes efficiency. In addition, the fan has been designed to reduce turbulence, making it quieter and more efficient.

Overall, the 3214J/39NR DC fan is an energy-efficient, reliable, and low-noise solution for air cooling applications. It is suitable for both industrial and commercial applications, making it a versatile and cost effective option for many businesses. The fan is designed to last for many years, making it a great long-term investment.
