General Information Item Product type Part no. Customer Project no. Modification Radial blower U65HN-024KS-6 N/A N/A Standard product Description This efficient and super silent high performance blower has been specifically designed for demanding intensive care ventilation or neonatology, where maximum dynamics and 100% oxygen resistance are required. U65HN, as well as U65MN and U65ML is a member of the U65 FORM FIT LINE, which provides a uniform pressure and flow behaviour and mounting concept. Features • Static pressure: 95 hPa, freeflow: 435 l/min • 24 VDC brushless DC-motor • Very quiet operation and highly efficient • Low inertia rotor • High frequency oscillatory ventilation at 10-12 Hz • O2 resistant 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
