Specification Radial Blower U51HP-012KM-43 General Information Item Product type Radial blower with integrated electronic motor driver U51HP-012KM-43 U51HP-012KM-42 (option with outlet port only) Standard product Description This compact 12 VDC multi-purpose blower can be used for various industrial pressure and vacuum applications. It provides an integrated brushless driver with set-speed input and tacho output and is optionally availabe without nozzle. Features • Static pressure: 26 hPa, freeflow: 380 l/min • 12 VDC brushless DC-motor • Analog speed control and tacho frequency signal • Compact design • Mounting flange with holes • Options with or without inlet port General Conditions Unless otherwise stated all data are measured at nominal voltage and are valid at 20 °C ambient temperature and 1.2 kg/m3 standard air density. Values listed are nominal and can vary depending on the installation conditions and due to component tolerances. Test setup according to ISO 5801 with standardized inlet and outlet chambers. Tolerances based on specified speed data according to ISO 13348, grade 4: pressure +/-10 %, power +16 %. Tolerances based on constant voltage: speed +/-10 %, pressure +/-21 %, power +33 %. For continuous blower operation please refer to specified maximum ratings. Performance data outside normal operating range plotted for informati
