QK08B-2EM.50.CH Ziehl-Abegg 230V AC Cross-flow Fan

Description

The Ziehl-Abegg QK08B-2EM.50.CH is a high-velocity AC cross-flow fan engineered for demanding applications requiring a powerful, linear, and laminar airflow distribution. This 628 mm extended-length unit is driven by a high-speed 2-pole external rotor motor, delivering an impressive 2470 RPM at 50Hz with a 0.27 kW power input. Designed for single-phase 230V operation, it provides exceptional air throw and uniformity across its entire discharge width. With a lightweight 5 kg construction and a compact 628 x 160 x 130 mm profile, it is optimized for space-constrained environments that still require high cooling capacity. Rated at IP10 and capable of withstanding ambient temperatures up to 70 °C, this fan ensures reliable, high-performance operation in specialized industrial and commercial ventilation systems.
