Ziehl-Abegg FN045-VDK.2F.V7P2 Axial Fan (170368) – 450 mm, 400V 3-Phase, Two-Speed (1280/970 rpm)

The Ziehl-Abegg FN045-VDK.2F.V7P2 (article 170368) is a 450 mm axial fan with FE2owlet sickle blades. The VDK type has a two-speed (Dahlander) 3-phase motor: the same fan can run at both high and low speed. The blade profile is derived from owl-wing aerodynamics; the serrated trailing edge and winglet tips produce noticeably lower noise at the same airflow.

Two-Speed 3-Phase Condenser Fan

Two speeds are the most sought-after feature in condenser fans: high speed in summer/full load, low speed in winter and at night. This keeps condensing pressure under control while reducing noise and energy consumption — and two stages are obtained without needing a fan speed controller. The motor is inside the rotor with thermal protection; it comes with a guard grille and operates in suction (V) direction.
