Description
The NMB 04028DA-12L-AU-02 is a compact 12V DC axial cooling fan from NMB Technologies, measuring 40x40x28mm. As a “low speed” variant, it offers a balance of moderate performance and relatively lower noise compared to its higher-speed counterparts in the same size. This fan operates at 0.20A (2.40W), reaching a speed of 10000 RPM. It delivers an airflow of 10.6 CFM and generates a static pressure of 0.440 inch-H2O. Equipped with durable ball bearings, it boasts a substantial life expectancy of 70,000 hours at 40°C. With its 4-wire configuration, it provides advanced features like PWM control for precise speed adjustment and a tachometer output for reliable monitoring, making it suitable for various electronic cooling applications where space is limited and controlled airflow is needed, at a noise level of 39.0 dBA.
