RH35M-4EK.4F.1R Ziehl-Abegg 230V 365mm AC Centrifugal Fan

Description

The Ziehl-Abegg RH35M-4EK.4F.1R is a high-efficiency single-phase AC backward-curved centrifugal fan featuring an upgraded 365 mm bionic Cpro composite impeller. Driven by a 4-pole external rotor motor, this unit is optimized for medium-duty air displacement in environments requiring single-phase (230V) power. Delivering a stable 1360 RPM at 50Hz with a nominal power input of 0.30 kW, it combines a lightweight 8 kg design with a robust IP54 protection rating. Engineered for stability in temperatures up to 70 °C, the RH35M-4EK.4F.1R utilizes specialized blue composite blades to minimize noise and turbulence, making it a reliable solution for precision cooling and commercial ventilation systems.
