DC fans are integral components of many types of electrical, heating, and cooling machines. The 09238RA-12N-EA-00 is just one of many models of DC fans available, and understanding the application field and working principle of this specific model can help users select the right type for their equipment.

This fan is best suited for applications that require a DC fan with an airflow up to 75 CFM (cubic feet per minute) at 0.5 in static pressure. It is especially ideal for devices and machines that require a cooling fan with a low noise level of only 29 dB. The 09238RA-12N-EA-00 also offers a long operating life of 20,000 hours with its sleeve bearing design.

Working Principle

The 09238RA-12N-EA-00 uses the same basic principle as all other DC fans: the electric motor creates a negative pressure that pulls air through the fan blades. The electric motor is powered by an external DC power source. The electrical current is controlled by an electronic circuit that adjusts the fans speed based on the temperature of the device it is cooling.

The fan blades on the 09238RA-12N-EA-00 are arranged in a seven-blade design with an aerofoil profile. This helps draw in more air and produces more cooling efficiency than fans with fewer blades. The fan motor is also designed to run more efficiently than others, with a maximum speed of around 2600 RPM.

Advantages

One of the main advantages of the 09238RA-12N-EA-00 is its low-noise level. Many DC fans create a lot of noise, but this model is one of the quietest on the market. This makes it ideal for devices that require cooling but must operate in noise-sensitive environments.

The long lifetime of the fan is another key advantage. With an expected operational time of over 20,000 hours, you can rely on the 09238RA-12N-EA-00 to provide consistent and reliable cooling without needing a replacement as often as other fans. This is especially beneficial for machine operators who need to maximize uptime.

Conclusion

The 09238RA-12N-EA-00 is a high-quality DC fan that is best suited for applications that require low-noise cooling with a maximum airflow of up to 75 CFM. Its seven-blade design and aerofoil profile produce more efficient cooling than other fans, while its long expected lifetime makes it a reliable choice for devices that require long periods of operation. Understanding the application field and working principles of this fan can help you select the right model for your specific needs.
