S4D011 DC fans are small-size, low noise, high-speed fans. They feature an impeller and frame that are made of thermally-resistant plastic. The impeller and the frame are designed for low vibration and reliable operation in high speed applications. S4D011 fans have a radial fan design which ensures that the air is blown directly into the application area with a minimal degree of turbulence. Furthermore, the fan blade pitch is optimized for increased air pressure and airflow.

S4D011 fans are suitable for cooling applications in electronic devices, personal computers and other commercial products. They can be used in any application where a high speed, low noise fan is needed. In addition, they are capable of providing adequate cooling performance in all types of environments, from indoor to outdoor applications.

In terms of technical data, the S4D011 fan has a speed range from 2000 rpm to 4500 rpm and an airflow range from 18 to 71 CFM. It also has an efficiency of up to 75% and an operating temperature range from -10℃ to 70℃. The fan also has a wide variety of control options, including PWM and voltage-based control. The PWM option allows users to set the desired fan speed, while the voltage-based control allows users to set the desired fan voltage. Moreover, the fan comes with a speed tachometer signal output which further facilitates the monitoring and control of fan speed.

The working principle of the S4D011 fan is based on the Bernoulli principle of fluid dynamics. The Bernoulli principle states that when a fluid flows in a confined space, it experiences a decrease in pressure. When the fan\'s blades rotate, the air passes through them and thus experiences a decrease in pressure. This decrease in pressure is what causes the air to be forced out of the fan at the back, creating the airflow.

S4D011 DC fans are reliable, efficient, and durable fans designed for a variety of cooling applications. Their versatile speed and airflow range, wide temperature range, and control options make them ideal for all types of applications. Furthermore, these fans are available in a variety of sizes, thus enabling users to find the fan that meets their application\'s requirements.
