4RRE25 250X56R-Z1902 - BACKWARD CURVED FAN 230 Va.c.
More information: "BACKWARD CURVED FAN 230 Va.c."
Radial fans with backwards-curved blades are used in suction, even without scroll, in high-speed applications. As a result of these characteristics, they can determine a high-pressure flow with reduced airflow. Radial backwards-curved fans have good air efficiency and a low noise level.
