DC Fans

DC fans are a type of electric fan powered by direct current. Fans driven by DC motors have been used for decades for cooling and ventilation efficiency. DC fans are usually smaller, lighter, and quieter than AC models, making them ideal for applications where the fans are used to control sound or airflow. A variety of DC fan sizes are available, ranging in diameter from 1.5 inches to as large as 12 inches.

The 618JH is an innovative DC fan of 12 inches. It is known for its high airflow of 120 CFM and its quiet running performance. This fan is able to provide a significant cooling effect in various application fields. It features a Nidec Ultraflo bearing with a lifespan of more than 50,000 hours. The 618JH is suitable for use in computer cases, office spaces, architectural installations, and industrial ventilation systems.

The 618JH makes use of a two-phase brushless DC motor with a rated voltage of 12 VDC. This motor is also known as a brushless DC electrical motor, or BLDC motor. It is designed to run at much higher efficiency and superior performance, compared to traditional AC models. The 618JH's motor has adjustable speed settings and can deliver up to 24.2 watts of power. This motor is also certified to meet RoHS, UL, and CE safety standards.

The 618JH also utilizes unique double fan blades, which allows it to rapidly move air with greater efficiency at lower noise levels. This type of fan blade has been designed to increase air displacement and reduce turbulence, making it ideal for situations where quiet operation is desired.

The 618JH's working principle is based on a strong induction magnetic field created by a permanent rare earth magnet, and electromagnets which are mounted on the top and bottom of the casing. When an electric current is passed through the electromagnets, the magnetic field interacts with the permanent magnet to repetitively attract and repel, creating a rotational force that drives the fan's blades. This force powers the blades which in turn push air out of the fan, thus providing a cooling effect.

The 618JH is a great example of a modern DC fan. It offers high cooling efficiency, superior performance, and a quiet operation. Its innovative design and unique features make it an excellent choice for a variety of applications.
