Specification Radial Blower U85HL-024KH-4 General Information Item Product type Radial blower with integrated electronic motor driver U85HL-024KH-4 U85HL-024KH-41 with inlet port (option) U85HL-024KH-42 with outlet port (option) U85HL-024KH-43 with inlet and outlet port (option) Standard product Description This versatile and powerful blower has been designed for cost sensitive applications. It provides an integrated brushless driver with set-speed input and tacho output and is optionally available with inlet and outlet nozzles. Features • Static pressure: 129 hPa, freeflow: 880 l/min • 24 VDC brushless DC-motor • Speed control and tacho frequency signal • Highly efficient, quiet operation • Aluminum heat sink • Two different mounting possibilities 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
