RVE45 DC Centrifugal Fan

Powerful, compact, quiet: RVE45

The next generation of our RV45 series, the RVE45 features the same dynamic air delivery in a similar compact footprint with the added benefit of built-in electronics. This new high performance series excels in rapid pressure changes and is ideal for a wide range of medical and industrial applications including ventilators, vacuum lifters, breathing masks, even filling bubble wrap! With more design freedom, greater efficiency, and significantly lower noise levels, the RVE45 is a powerhouse that is ready to work for you.

What the RVE45 has to offer, and more importantly, what you have to gain from it:

The RVE45’s dynamic EC internal rotor motor easily adapts to rapid pressure changes, switching quickly and reliably between high and considerably reduced pressures. The high nominal speed of 38,000 rpm produces exactly the dynamic power required, which is also supported by the rotor’s low moment of inertia. Active braking ensures a similar response at negative acceleration. Speed changes from 0 to 38,000 rpm to less than 500 ms are no problem for the RVE45. For you, this means the air flow is always dosed exactly as required.

Vibration-absorbing materials and an optimized aerodynamic design ensure that the RVE45 operates quietly, and thanks to maintenance-free ball bearings, it can continue to do so for many years. For you, this means that your products work reliably long-term and at significantly lower noise levels.

The rotor is intentionally light, which results in low power consumption at high dynamic performance. Speed control is possible with a PWM signal or analog voltage which reduces the energy consumption to exactly what is required. The fan can be monitored via a tach signal or alarm signal which proactively reduces downtimes (or even prevents them completely!). For you, this mean maximized efficiency. You can adjust the fan characteristics to your individual needs and environmental conditions by parameterizing them during the design-in phase.

The space-saving motor design and special high-performance magnets make the RVE45 particularly compact and lightweight. For you, this means more design freedom and smaller sizes for all of your applications.
