Raptor SDA

The Elta Raptor SDA is a short cased axial fan for installation within ductwork, built around the Ziehl-Abegg FE2owlet aerofoil impeller. Its sickle-shaped blades with serrated trailing edges and winglets — a design based on bionic insights — deliver quiet, efficient airflow with strong durability, making the SDA a smart choice where noise matters as much as performance.

We offer all eight sizes from 250mm to 630mm diameter, in both AC and energy-saving EC versions, with 4-pole, 6-pole and dual-speed motor options across the range. The Raptor SDA achieves air volume flow rates up to 4.60 m³/s and static pressures up to 290 Pa, at operating temperatures up to +70°C.
