Ziehl-Abegg FN050-6EK.4F.V7P1 Axial Fan (154149) – 500 mm, 230V, 900 RPM, 5,770 m³/h

The Ziehl-Abegg FN050-6EK.4F.V7P1 (article 154149) is a 500 mm axial fan with FE2owlet sickle blades. The blade profile is derived from owl-wing aerodynamics: with its serrated trailing edge and winglet tips, it produces noticeably lower noise at the same airflow. The 6-pole external rotor motor runs at ~900 rpm — the choice of the low-speed, quiet class for condensing units and cold room units.

900 RPM Quiet Condenser / Evaporator Fan

Compared with the 4-pole (1,380 rpm) version of the same housing, it produces less noise and draws less power; the 900 rpm model is standard for operations with night-time operating restrictions and for cold rooms near residential areas. The motor is inside the rotor with thermal protection; the fan comes with a guard grille and operates in suction (V) direction.
