DC Fans are electric motors that power fans with direct current (DC). DC fans provide a highly efficient and cost-effective solution for various cooling and ventilation applications. They offer superior performance compared to regular AC fans, making them a popular choice for HVAC and other commercial and industrial applications. The 109R0812G402 is a DC fan that can be used in a variety of applications.

Features

The 109R0812G402 is designed to deliver superior performance in terms of airflow, noise level, durability, and efficiency. It features a robust polypropylene frame with UL94V-0 flame-retardant blades for enhanced safety and protection. The fan operates at a voltage of 12V DC and provides an airflow of 142.6 CFM at a maximum speed of 4000 RPM. It is equipped with a PWM input that allows for speed control, making it ideal for applications that require precise temperature control. The fan also features a heavy-duty ball bearing and a tachometer output.

Application Field

The 109R0812G402 DC fan is commonly used in HVAC commercial and industrial applications, as well as for cooling and ventilation in industrial enclosures, servers, and electronics. It is also commonly used in the automotive industry as a low power cooling fan for EVs, hybrid vehicles, and fuel cell vehicles. The fan is also used as an auxiliary cooling fan for air conditioning systems and other applications that require efficient cooling. Additionally, it can be used in aircraft, as well as in household appliances.

Working Principle

The 109R0812G402 is powered by direct current, meaning the magnitude and direction of the current does not change. This creates a continuous electromagnetic field in the coil of the fan, creating an attractive force on the motor armature. This results in a rotation, which is transferred to the fan blades, creating an airflow. The speed of rotation is regulated by the voltage, with higher voltage resulting in higher speeds. The PWM input also allows for precision speed control, allowing the fan to be precisely adjusted to meet the requirements of the application.

Conclusion

The 109R0812G402 is a highly efficient and reliable DC fan that can be used in a wide range of applications, from HVAC commercial and industrial to automotive and aircraft. It features a robust frame and UL94V-0 flame-retardant blades for added safety and protection. The fan is powered by 12V DC and can provide an airflow of 142.6 CFM at a maximum speed of 4000 RPM. The PWM input allows for precision speed control, making it ideal for applications that require precise temperature control. This makes the 109R0812G402 an ideal choice for a variety of cooling and ventilation applications.
