Description
The ZIEHL-ABEGG FN071-SDK.6F.V7P1 is a specialized 400 V 3-Phase Industrial Axial Fan with a 710 mm blade diameter, engineered to comply with the JB/T 6411 standard for high-reliability ventilation. Driven by a high-efficiency MK137-8DK.10.L 8-pole external rotor asynchronous motor with THCL 155 (Class F) insulation and IP54 protection, this unit is optimized for 60 Hz operation. It features a dual-speed Delta/Star (Δ/Y) configuration, delivering a precise Power Consumption of 940 W at 900 RPM (Delta) and 620 W at 690 RPM (Star), while maintaining a static pressure of up to 161 Pa. Constructed with premium sickle-shaped aluminum blades and a 26.00 kg heavy-duty frame with moisture and hot climate protection, this German-engineered unit ensures exceptional acoustic performance, ranging from 69 to 78 dB, and long-term mechanical stability for mission-critical industrial applications at the end.
