ebm-papst AC axial compact fans
The ranges of AC axial compact fans from ebm-papst are suitable for high air performance with moderate pressure build up. The fans are extremely flat, thanks to the space saving integrated motor. The outstanding features of axial fans are their small installlation depth, low noise level and exceptional efficiency, and are particularly well suited for air flow through heat exchangers. Furthermore, with GreenTech EC technology, the axial fan becomes an intelligent energy saver for an extremely wide range of applications. The axial fan, the function of which is similar to a propeller, moves the air axially, parallel to the revolving motor shaft. The ebm-papst external rotor motor is integrated directly into the axial impeller, forming a compact axial fan unit. Using GreenTech EC motors also enables precision control of the air flow. They are available with tacho output, linear or PWM input, bus-connectable interfaces and many other features.
