The R4E280-AD08-05 from EBM Papst is a high-efficiency, casing-free radial fan designed to handle large air volumes. The fan is driven by a voltage-controlled, external rotor type asynchronous motor, which ensures reliable and energy-efficient performance. The fan wheel is equipped with backward-curved blades made of black-painted steel, which contributes to low noise levels and increased efficiency. This fan is ideal for use in applications such as air handling units, heat recovery systems and general ventilation where robust, quiet and efficient air circulation is required. With a built-in thermal switch for motor protection and an IP44-rated design, the R4E280-AD08-05 ensures operational reliability and a long service life under demanding conditions. See the data sheet on the product page for full technical information.
