Specification Radial Blower U85MX-024KE-4 General Information Item Product type Radial blower with integrated electronic motor driver U85MX-024KE-4 U85MX-024KE-41 with inlet port (option) U85MX-024KE-42 with outlet port (option) U85MX-024KE-43 with inlet and outlet port (option) Standard product Description The versatile, high-power blower can be widely used for industrial or medical applications, where highest vacuum or pressure performance is needed, i.e. for cough therapy, dental suction, vacuum handling and many more. Features • Static pressure: 123 hPa, freeflow: 860 l/min • 21 VDC brushless DC motor • Analog speed control and tacho frequency signal • Highly efficient, quiet operation • Aluminium heat sink • Mounting flange with holes 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
