RH35F-QDK.6K.2R Ziehl-Abegg 400VAC 350mm AC Centrifugal Fan

Description

The Ziehl-Abegg RH35F-QDK.6K.2R is a high-performance 400 VAC AC Centrifugal Fan (Motorized Impeller) with an impeller size of 350 mm (13.78 in), engineered to deliver high static pressure and high-volume air movement for demanding HVAC, refrigeration, and industrial ventilation systems. Constructed with a high-efficiency backward-curved motorized impeller, an AC external rotor motor, and precision ball bearings, it has a net weight of 24 kg. Driven by a 3-phase AC motor operating at a nominal voltage of 400 VAC (±10%) at 50 Hz across YY/Y connection modes, it draws a rated current of 3.3 / 0.80 A with a power consumption (P1) of 1.70 / 0.23 kW. Operating at nominal speeds of 2850 / 1460 RPM with a power factor of 0.74, it provides a Max. Air Flow of 3200 / 1650 CFM (5440 / 2805 m³/h / 90.67 / 46.75 m³/min) and a Max. Static Pressure of 115.00 mmH₂O (1127.84 Pa / 4.53 inAq) with a noise level of 74.0 dBA. Designed with a terminal box for electrical connection, IP54 ingress protection, and Class 155 (THCL 155) insulation, it operates reliably across temperatures from -20 to +60 °C and complies with CE, EAC, and RoHS agency approvals.
