Description
The ebm-papst 252M is a precision-engineered micro DC Axial Fan designed for thermal management in ultra-compact electronic assemblies. Featuring advanced Sintec sleeve bearing technology, this unit ensures low-noise operation and extended service life by optimizing lubricant retention and reducing friction. The 25x25x8mm chassis is constructed from fiberglass-reinforced PBT, providing exceptional structural rigidity and thermal stability. With a nominal power consumption of just 0.45W, the 252 M delivers consistent airflow to lower thermal impedance in sensitive components without imposing significant energy demands. Its aerodynamic impeller design minimizes turbulence, making it an ideal solution for applications requiring a balance between airflow performance and acoustic discretion.
