DC Fans

DC fans are powered by direct current (DC) motors and are usually used in low power applications. DC fans are typically found in devices such as computer systems, servers, data centers, and other environments where a reliable source of cooling is essential to maintain the proper functioning of the devices.

The MR4020E12B-RSR is a type of DC fan and is designed to provide reliable cooling in a wide variety of applications. This fan is designed to be used in applications where the airflow rate is not critical, such as in computers, servers, data centers, and other environments. It features a special design that enables it to run at a high static pressure even at low airflow.

Application Field

The MR4020E12B-RSR can be used in a variety of applications, such as server racks, data centers, and other environments requiring reliable cooling. The fan is designed to be used in applications where the airflow rate is not critical, such as in computers, servers, data centers, and other environments requiring reliable cooling. It is also designed to be used in high-performance applications, such as in servers and computer systems. Additionally, the fan is suitable for applications requiring low noise and high static pressure.

Working Principle

The working principle of the MR4020E12B-RSR is straightforward. The fan uses a DC motor to move the air through the fan blades. The motor is powered by a direct current, which is sent to the fan by a controller, such as a PWM (Pulse Width Modulation) controller. The PWM controller is used to adjust the speed of the fan, enabling the fan to produce the desired level of airflow in the application.

The fan blades are specially designed to provide high static pressure and low noise at lower airflow rates. As the airflow rate increases, the blades rotate faster, providing higher levels of static pressure and noise. As the airflow rate decreases, the blades rotate slower, providing lower levels of static pressure and noise.

The MR4020E12B-RSR is designed to run at a low noise level even at high airflow rates, making it suitable for applications where noise reduction is important. Additionally, the fan is designed to operate in adverse temperatures and humidity conditions, making it suitable for a wide range of applications.
