Description
The ZIEHL-ABEGG QR08A-2EM.50.CH is a high-capacity 230VAC Industrial AC Cross-flow Fan with an impeller length of 500 mm and a total length of 537 mm, specifically engineered for uniform tangential air delivery in mission-critical industrial frequency converters and high-end air curtain systems. Driven by a high-torque external rotor motor with integrated thermal protection and THCL130 (Class B) insulation, this unit features a precise Max. Power Consumption of 0.24 kW and a Max. Current Draw of 1.05 A at 230 V AC (50 Hz). Operating at a high rated speed of 2300 RPM, it delivers a powerful, non-turbulent laminar airflow characterized by an efficiency grade of N=28.4 to ensure optimal heat extraction in high-impedance environments. Constructed with a heavy-duty galvanized sheet steel impeller and a rugged die-cast aluminum motor housing featuring precision dual ball bearings, this 5.0 kg German-made unit ensures maximum mechanical stability and long-term performance for integrated industrial applications at the end.
