Centrifugal fans from ebm-papst are available with forward or backward curved blades. The low-noise centrifugal fans and blowers with forward curved blades are also supplied with a scroll housing. The centrifugal fans with backward curved blades are designed for operating without a scroll housing. For the centrifugal fans with external rotor motors, the motor is positioned in the impeller, which results in an especially compact design in addition to optimal cooling of the motor. The entire product line is available in both AC and GreenTech EC technology.

If the required cooling air has to be turned 90° or if the system resistance is too high for an axial fan, radial fans are the most effective. ebm-papst offers not only motor/blower assemblies but also radial fan packages that include the inlet ring, power connector and housing for simpler installation.

All the facts of ebm-papst centrifugal fans and blowers at a glance:

3）“RadiPac” EC medium-pressure fans

4）Compact design with external rotor motor technology

5）Comprehensive series for every application

6）100% speed-controlled through analogue or serial interface

7）High efficiency through use of GreenTech EC technology

8）Quiet operation thanks to optimised flow regulation and ingenious commutation of the EC motor

9）Easy commissioning with components matched to each other: control/motor/fan

10）Extensive range of accessories

The best example: RadiCal

Where HyBlade® is for axial fans, RadiCal is for centrifugal fans: another breakthrough in ventilation and air-conditioning technology. The radical features are both the noise reduction and the additional reduction of energy consumption. As with the HyBlade®, the fan impeller of the RadiCal is made of fibreglass-reinforced plastic. This enables an aerodynamically optimised shape, which cuts the noise level in half and reduces the power requirement significantly.

We have also evolved the GreenTech EC motors or, more specifically, have miniaturised them. This gives the fans significantly more compact dimensions, allowing them to replace existing AC fans without any problems. In conjunction with optimised motor thermal management and increased efficiency, this provides energy savings of up to 50 % compared to AC solutions. Thus the RadiCal not only meets all existing environmental directives with ease, but is also ideally equipped for the future.

RadiCal fans from ebm-papst are available in various sizes and power stages for an extremely wide variety of applications – by request, also as ready-to-install modules.
