Description
The ebmpapst R1G225-AF11-21 is a highly efficient 48V DC EC centrifugal fan with backward-curved blades. It functions as a motorized impeller with an impeller diameter of 225mm. Operating at 48V DC, it consumes 95W of power, drawing 2.2A of current, and spins at 2700 RPM. This fan delivers a significant airflow of 1130 m³/h / 665 CFM and operates with a noise level of 67 dBA. It is rated IP44 for protection, features robust ball bearings, and utilizes a plastic impeller with a black-painted rotor surface. Its EC motor technology with integrated electronics and speed control features makes it ideal for precision ventilation in applications such as telecommunication cabinets, air purification systems, and other controlled environments.
