Description
The Ziehl-Abegg RE22P-2DK.3F.5R is a high-performance AC backward-curved centrifugal fan featuring the advanced bionic Cpro composite impeller. Driven by a powerful 3-phase external rotor motor, this 225 mm unit is engineered for versatile industrial applications, supporting wide voltage and frequency ranges including 400V 50/60Hz and 480V 60Hz. With a robust 7 kg construction and IP54 protection, it is designed to deliver intense static pressure—up to 620 Pa at 480V—making it ideal for overcoming high system resistance in dense electronic enclosures and industrial ventilation. Its maintenance-free ball bearing system and high-temperature tolerance up to 70 °C ensure reliable S1 continuous operation in demanding thermal management environments.
