The R3G250-AZ02-01 from EBM-Papst is a motorized impeller system with backward-curved blades, belonging to the category of blowers and centrifugal fans. The unit combines a 250 mm fan impeller made of PA plastic with an integrated EC motor for high efficiency and precise control. With an airflow of 805 m³/h and a static pressure of 322 Pa, it is ideal for demanding ventilation and air handling applications.
Thanks to the integrated control electronics package with soft start, power limiter, and support for 0–10 V DC or PWM signal, the R3G250-AZ02-01 is easy to integrate into modern control systems. It is suitable for installers and OEM manufacturers who need a compact, energy-efficient solution with flexible mounting options.
