DC fans, also known as an electronically commutated motor type fan, provide better performance than AC fans through boosted efficiency, lower emissions,better airflow, longer life and quieter operation.

Application fields of DC fans cover a wide range, for example, server rooms, robotics, lighting, cooling systems, etc. The JQ48R7/031437 DC fan is an example in these application fields. This fan is mostly used in complex equipment installation rooms, such as light boxes, railway signals, telecommunications systems, automation equipment, and other equipments installed with high temperature.

The working principle of JQ48R7/031437 DC fan is simple yet effective. It uses a low-voltage (typically 6V or 24V) DC motor to start up the fan. The DC motor is connected to a thermally protected capacitor switch, which comes with small, low-current electronics. This switch turns the fan on when the ambient temperature rises above a set point. When air temperature drops below the set point, it shuts off the fan automatically.

Another great advantage of this DC fan is its ability to operate in a wider range of temperatures, from -40°F to 212°F (-40°C to 100°C). This is because the thermally protected capacitor switch can detect the temperature changes quickly and switch the fan on or off instantly. This feature allows it to perform better than AC fans in extreme temperature conditions.

Furthermore, the JQ48R7/031437 DC fan is more reliable than an AC fan, due to its increased efficiency in airflow and low noise level. It has an enclosed bearing system and an efficient motor design for improved performance, and the motor is sealed for additional protection. This makes the fan suitable for applications in dusty or wet environments.

The DC fan also has a higher life expectancy than the AC fan. This is thanks to the low-voltage motor and its components that require no maintenance. Furthermore, the fan has a robust construction for more reliable performance and stability. Together with the thermally protected capacitor switch, all these features guarantee a long life for the DC fan.

Overall, the JQ48R7/031437 DC fan is a powerful and reliable product, suitable for a vast number of applications. It can sustain high temperatures and operate reliably for a long time. With its wide temperature range, lower noise level, improved performance and stability, the DC fan is the right choice for any application.
