The R1G190-AC11-11 is a motorized impeller from the R1G190 series, functioning as a centrifugal fan with backward-curved blades for high aerodynamic efficiency. Based on data for the series, it operates on a 48 VDC nominal voltage within a 36 to 57 V range, consuming 71 W of power and reaching a speed of 3200 RPM. This model delivers an airflow of 321 CFM at free air and has a noise level of 68 dBA. The impeller is made from PA 6.6 plastic, and the fan features integrated electronics with reverse polarity and locked-rotor protection, a tachometer output, and durable ball bearings. Its clockwise rotation and robust design make it suitable for demanding cooling and ventilation systems.
