General Information Item Product type Part no. Customer Project no. Modification Radial blower U65ML-024KT-5 N/A N/A Standard product Description This versatile, medical respiration blower has been designed for sleep apnea and homecare applications. It It can be operated dynamically, has a very low vibration and noise emission and comprehends a steadily declining pressure/flow curve. U65ML, as well as U65HN and U65MN is a member of the U65 FORM FIT LINE, which provides a uniform pressure and flow behaviour and mounting concept. Features • Static pressure: 43 hPa, freeflow: 295 l/min • 24 VDC brushless DC-motor • Highly efficient • Very quiet operation • Low inertia rotor 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 information only. 1
