DC Fans or direct current fans as they are popularly known are a type of cooling device used across different industries. They are used to manage and control the internal temperatures of various electrical and mechanical systems. The SG40281B1-000U-S99 model by Cooler Master is a prime example of such a device. This article will discuss its application fields and working principle.The SG40281B1-000U-S99 model is a DC fan ideal for cooling electronic components such as CPUs, GPUs, chipsets, and other components. It is equipped with a fan blade extruded from high-density polyethylene. This material not only makes it rugged and durable but also helps it to last longer and effectively lower temperatures. The fan can manage temperatures of up to 60 degrees Celsius, making it suitable for industrial applications and places with harsh climates.What sets the SG40281B1-000U-S99 model apart from other fans is its unique ‘Ultra Smooth Long Life’ bearing. This bearing helps to keep the fan assembly in balance and reduces friction between the rotor and stator. The fan is rated at 1600 RPM at 12V, putting it at the top of its class for speed and efficiency. It boasts an impressive airflow rate of 67.2 cubic feet per minute and a maximum static pressure of 2.2 mmH2O.The SG40281B1-000U-S99 DC fan also features a humidification technology to help keep humidity levels in check. It is equipped with a unique humidity-controlled impeller which can control both the fan speed and direction. This helps to address the issue of dust accumulation, as well as prevent any possible risk of condensation build-up.In terms of working principle, the SG40281B1-000U-S99 DC fan operates by converting electrical energy into mechanical energy. This is achieved through a series of windings contained within the fan. When the fan is powered up, an electric current is induced and this sets the fan into motion. As air passes through the fan blades and the windings rotate, a pressure differential is created and this results in air being pushed through the fan.The SG40281B1-000U-S99 model is a reliable and effective cooling solution for your industrial or commercial needs. It is designed to withstand the toughest of conditions while maintaining its superior performance with low noise levels. Thanks to its unique fan blade material and ‘Ultra Smooth Long Life’ bearing, you can be sure of a long-lasting and dependable fan system. The efficient humidity-controlled impeller also ensures dust-free and condensation-free operation. With the SG40281B1-000U-S99, you can be sure of a safe and reliable cooling solution.
