This fan also has the unique feature of a ball bearing system which is improved for extended life. The motor of the fan is protected with a polyamide coating for further durability and dust resistance. Finally, the G4020H12B1-RSR is UL, RoHS, and CE certified.

Application Fields

The G4020H12B1-RSR fan is suited to be used in high-speed cooling applications due to its high speed and air pressure. This fan can be used in a variety of ways such as cooling systems in audio/video equipment, computers, telecoms, and industrial systems. The fan can also be used to cool radiators in automobiles as well as other power sources. The noise-reducing features of this fan make it suitable to be used in environments such as libraries and other where a low sound level is necessary. It can also be used for ventilation and dust extraction devices.

Working Principle

The G4020H12B1-RSR is a DC type fan, meaning it does not require an external source of power. Instead, it is powered by a 12V DC power source. The fan operates by using an electromagnet which is magnetically turned into a DC electric motor, referred to as a brushless DC motor. This motor is composed of permanent magnets and an electromagnet which interacts with each other to create an electromagnetic field. This is what causes the shaft of the motor to rotate and in turn creates air flow.

The G4020H12B1-RSR uses a brushless motor which eliminates the need for brushes, which can wear down if the motor is used for long periods of time. The ball bearings of the fan also contribute to an improved air flow along with its heat-resistant and dust resistant properties.

Conclusion

The G4020H12B1-RSR is a robust and reliable DC fan that is suitable for cooling in a variety of applications and conditions. The fan is designed for low noise operation and is certified for safety. The fan uses a brushless DC motor to produce air flow which provides efficient cooling capabilities while consuming a minimal amount of power. This fan is able to provide a high-speed output and is able to resist wear and tear for extended life.
