Compact, high-performance and efficient – this is the fan program from ebm-papst. They are versatile all-round talents for the widest variety of applications, and remain the most tried-and-tested means of moving air in electronics cooling. Over the years, we have kept improving the performance and energy efficiency, setting the standard for quiet fans.

Axial, centrifugal or diagonal – all point the way towards the future Fans from ebm-papst, which have long been the standard in electronics cooling, are available in 3 designs: Our Axial Fans are suitable for high air performance with moderate pressure build-up. The flow of air through the fan blades is parallel to the rotational axis. The space-saving integration of the motor makes them extremely flat.

The Centrifugal Fans from ebm-papst are the unbeatable high-pressure specialists with 90° air deflection and carefully optimised impellers.

For our Diagonal Fans the outflow is diagonal. This compresses the air more – for a higher air flow at high pressure build-up. This makes them particularly well suited for cooling-intensive applications with tightly spaced components.

For each type, ebm-papst offers a large selection of fans, which are available in AC, DC or GreenTech EC design, for all voltages and in all standard sizes. With preinstalled electronics, they also offer numerous additional options and can also be networked intelligently with the respective device logic.

• Voltage range: (Axial Fans - 115-230 VAC, 5-72 VDC) (Diagonal fans - 12-72 VDC) (Centrifugal fans - 12-48 VDC, 115-230 VAC)
• Air volume: (Axial Fans - 2-1,200 m3/h) (Diagonal fans - 250-700 m3/h) (Centrifugal fans - 10-500 m3/h)
• Power input: (Axial Fans - 0.5-100 W) (Diagonal fans - 20-90 W) (Centrifugal fans - 2-160 W)
• Back pressure: (up to 550 Pa) (Diagonal fans - up to 270 Pa) (Centrifugal fans - 50-1,600 Pa)

ebm-papst centrifugal fans are available with forward and backward-curved blades. The quiet-running centrifugal fans with forward-curved blades are also supplied with a scroll housing. The centrifugal fans with backward-curved blades are designed as freewheel fans and do not require a scroll housing. In the case of centrifugal fans with external rotor motors, the motor is positioned in the impeller, ensuring not just optimum cooling of the motor, but also a particularly compact design. The entire range is available with both AC and GreenTech EC technology. In addition to being particularly energy-saving, the integrated electronics also make it possible to implement any control, monitoring and maintenance functions – for both the smart home and Industry 4.0.
