DC Fans are one of the most important types of fans in terms of airflow, motor control, and noise control. The 109P0412F302, also referred to as the “DC FAN4”, is a widely used DC fan for high-load applications. It has long been used by many companies as a standard fan for cooling solutions.

The 109P0412F302 is a 4-wire type fan, with two signal wires and two power wires. This fan can run at speeds as low as 5 volts and as high as 12 volts. The 109P0412F302 operates with a sliding bearing type known as a dual ball bearing that supports up to 16,000 RPM. This fan features a 70.1 CFM (cubic feet per minute) output at 3.30 to 12.0 volts, making it one of the most powerful DC fans available.

The 109P0412F302 is primarily used in electronics, cooling, and air ventilation. It is often used in computer chassis to cool CPU, GPUs, RAM and other electrical components. It is also used in automotive applications such as radiators, cooling pumps, and transmission cooling systems. The fan can also be used in industrial applications for cooling pumps, compressors, and air-conditioning systems.

The 109P0412F302 works on a principle known as the “pressure-difference principle”. This principle states that when air moves from one point to another, it creates a pressure differential. This pressure differential can then be used to generate airflow. In the case of the 109P0412F302, the fan blades are designed to push air towards the center of the fan, creating a higher pressure on the inside of the fan. This higher pressure causes the air outside the fan to be drawn into the fan, creating an overall airflow.

The 109P0412F302 also works on a principle known as the “counterflow principle”. This principle states that when air is forced through a narrow opening, it increases its speed and creates a vacuum behind it. The 109P0412F302 utilizes this principle by placing the fan blades at an angle relative to the fan body. This results in the fan blades pulling air outwards from the center of the fan and pushing it radially towards the edges. This creates a higher pressure on the outside of the fan, resulting in an overall airflow.

The 109P0412F302 is a high-performing DC fan and is widely used for cooling and air ventilation. Its high-efficiency and low-noise operation make it an ideal choice for applications requiring a reliable fan. Its ability to generate high airflow and low noise levels makes it a popular choice for many applications, from cooling computer components to automotive and industrial uses.
