The ebmpapst 4656ZWU is a compact axial cooling fan intended for industrial automation and electronic equipment. It integrates into equipment enclosures and automation modules where localized heat loads require stable air exchange in limited space.
Key selection data includes a 230 V supply, airflow up to 180 m³/h, and maximum pressure of 80 Pa. The axial flow path provides efficient cooling, while pressure performance helps move air through guards, filters and restricted passages. The datasheet identifies ball-bearing motor support for durable motor support. Clear inlet and outlet spacing helps control turbulence and system noise. Matching the electrical supply and duty point supports energy-efficient, reliable operation and long service life.
OEM buyers and automation engineers can consider the 4656ZWU for space-conscious cooling. Confirm airflow demand, wiring, mounting and temperature limits before design-in. Proper installation supports stable thermal control and long fan life.
