DC Fans have become increasingly important as they are capable of providing large amounts of air movement and energy efficiency. The MR4020L12B2-RSR is a well-regarded type of DC Fan, widely used for its good performance and reliable operation. Understanding some of the key features of this kind of DC Fan is essential for selecting the right fan for the job.

The MR4020L12B2-RSR type DC Fan is primarily used in order to cool down high-performance electronic components, though they can also be used in automotive and domestic applications. They are equipped with a brushless motor and long-life bearings which are designed to provide a low level of vibration and noise. This is done by eliminating the rotating magnetic field generated by the brushes of other motors, as well as by stabilizing the fan’s RPM.

The fan is capable of providing a maximum flow rate of up to 39.4 CFM, as well as a maximum static pressure of 0.8 inch of H2O. It has a lifetime of over 50,000 hours, and an operating temperature range from -30°C to 70°C, making it capable of operating in a wide range of environments. Additionally, it is also energy saving and is typically 40-60% more efficient than other fans in the same class.

The MR4020L12B2-RSR DC Fan motor works by having two permanent magnets fixed on the rotor and an armature wound on the stator. When the rotor moves, it induces a current in the armature, creating a rotating magnetic field which then forces the rotor to rotate in the same direction. This magnetic field is constantly shifted by changing the polarity of the current going through the armature, allowing the rotor to rotate smoothly.

The MR4020L12B2-RSR DC Fan’s bearings are able to provide high-reliability and low-maintenance operation, through their effective use of steel balls and seals. Steel balls are used to provide excellent load bearing capability and smooth motion, as well as eliminating the need for periodic lubrication. The fan also features a sealed bearing system which eliminates the need for periodic maintenance, as well as providing extra protection against dust and contaminants.

The MR4020L12B2-RSR DC Fan is a well-designed piece of equipment, perfect for a variety of cooling applications. Through its combination of energy-efficiency, low noise and high performance and reliability, it is a particularly suitable type of fan for cooling high-performance electronic components. It is also suitable for automotive and domestic applications, owing to its long lifetime and improved sealed bearing system.
