The latest SEPA® delivery program now includes the axial fan MFB40H12HA, which complements the MFB40H series (40mm x 40mm x 10mm). Although the same in size, a boost in performance of approx. 28% is achieved with a maximum air flow of 13.2 m3/h.

Three models with varying speed allow the fans to be used in a variety of industrial applications. These applications also benefit from the use of high-quality ball bearings (L10 = 95.000 h, MTBF = 280.000@20°C). For monitoring the speed, the model is equipped with a tacho output similar to a square-wave signal which has a frequency that is equivalent to twice the rotor speed. The typical rotor speed of the new model is 7.000 rpm. Thanks to the low rotor weight, precision balancing and the extremely robust and stable frame made from glass-fibre reinforced PBT, the fan has a high resistance to shock and vibration. Standard features also include the permanent protection against reverse polarity, blocking and thermal overload.
