Fans used in the medical sector for example in sleep apnea breath- With its big performance and all features designed into a 64 x 69.5 x ing devices have to meet particularly high standards with regard to 54.5 mm package smaller than a tennis ball, the RV45 is the ideal dynamics, smooth operation, reliability, acoustics and compactness. solution for any number of demanding tasks. These are found not only in the medical sector but also for industrial applications such as The ebm-papst centrifugal fan RV45 passes every test with flying col- fuel cells, smoke detectors or packaging machines. ors: 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 consider- ably 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-papstRV45 power modul, which enables the RV45 to be used in a wide range of industrial sec- tors as well. 2
