Description
The ebmpapst 4394M is a highly reliable DC Axial Fan built in a compact 120 x 120 x 32 mm size. Operating on 24 V DC with low power consumption (2.8 W), this fan is optimized for quiet operation (39 dB(A)) and robust performance. Its durable metal housing and 24V compatibility make it an ideal and common cooling solution for industrial Variable Frequency Drives (VFDs) and power converters where reliable, low-noise heat extraction is required.

Application
The ebmpapst 4394M is primarily designed for industrial power electronics and motor control systems. Its shallow 32mm depth and 24V DC compatibility make it a standard choice for integration into Variable Frequency Drives (VFDs), inverters, and large industrial power supplies. The durable metal construction ensures the fan can withstand the typical heat and vibration within a motor control cabinet, providing reliable, low-noise cooling for sensitive IGBTs or heat sinks.
