General Information Item Product type Tube fan with integrated electronic motor driver D343P-024KM-4 with flange at outlet (option) D344P-024KM-4 with flange at inlet (option) Customer N/A Modification Standard product Description In contrast to the Flat Fans, the Micronel Tube Fans offer increased pressure performance while still maintaining a high volume flow. They all feature extremely quiet and efficient operation while offering extreme reliability and life expectancy. Features • Static pressure 6.69 hPa, freeflow 490 l/min • 24 VDC brushless DC-motor • Speed control and tacho frequency signal • Small dimensions through slim design • Options for 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 information only.
