Fans used in the medical sector – for example in sleep apnea breathing devices – have to meet particularly high standards with regard to dynamics, smooth operation, reliability, acoustics and compactness. The ebm-papst centrifugal fan RV45 passes every test with flying colors: Its extremely dynamic EC internal rotor motor supports flexible adaptation to the breathing sequence and switches both quickly and reliably between a high inflation pressure (inhalation) and a considerably lower pressure for unobstructed exhalation. The high speed of up to 50,000 rpm produces exactly the power required, assisted by the low moment of inertia of the rotor. Vibration absorbing materials and ideal aerodynamics ensure particularly quiet operation – over a period of many years thanks to maintenance-free ball bearings. Having been designed for external control, users can employ their own systems or work with the ebm-papst "RV45 power module", which enables the RV45 to be used in a wide range of industrial sectors as well. 2 With its big performance and all features designed into a 64 x 69.5 x 54.5 mm package smaller than a tennis ball, the RV45 is the ideal solution for any number of demanding tasks. These are found not only in the medical sector but also for industrial applications such as fuel cells, smoke detectors or packaging machines. You don't have to be big to be a great performer. Breathing device applications demand fans with highly dynamic characteristics. A high pressure is required at the start of the breathing sequence and a low pressure at the end. In practice, that means pressure fluctuations between 400 Pa and 2000 Pa. With a centrifugal impeller, the flow quantity and delivery pressure increase with increasing speed. The high nominal speed of 40,000 rpm thus produces dynamic power output – with a compact design. 1 16 12 8 4 for plastic screw Ø 2,5 maximum screw depth 6 mm 63.9 33.5 6.2 63.9 * 22 12 0 34.6 23.1 64.1 18 0 ( 48.6 ) 12 * 37 53 * Voltage range * Sound pressure ** with Hall sensors without Hall sensors Power consumption Nominal speed Temperature range Service life L10 (20°C) ebm-papst standard Service life L10 (Tmax) ebm-papst standard Life expectancy L10, IPC (25°C) Type Item number l/min cfm VDC-1 VDC dB(A) / W rpm °C Hours Hours RV45-3/14 9593505001 410 14.5 24 7...30 49 43 40,000 -20...+70 22,500/7,500 50,000 RV45-3/14S 9593505002 410 14.5 24 7...30 49 43 40,000 -20...+70 22,500/7,500 50,000 Nominal data Characteristic curve Nominal voltage 69.5 Air flow 54.95 Air flow 69.5 * Depending on the customer's actuation electronics. ** Measured at 1,000 Pa and a distance of 1 m above the intake side.
