Big Dutchman products

Axial fans are ideally suited for incorporation into walls. Their frame has an aerodynamic shape and is made of stable plastic or corrosion-resistant metal. The blades are made of aluminium in a moulded die casting process and are exceptionally efficient. Big Dutchman offers so-called FC, FF and FN fans. The new generation (FF and FN fans) has serrated blades, imitating the wings of an owl during its silent flight (bionics). FF and FN fans therefore consume even less power; they are extremely resistant to pressure.

The AirMaster V140 fans produce a high air flow rate where there is much resistance. They are therefore a good choice if the housing equipment in barns with tunnel ventilation causes high resistance, e.g. in houses with multi-tiered cage systems. An unobstructed air flow is not possible in such houses, unlike in broiler houses.The V140 meets the same exacting requirements regarding quality of the material, aerodynamics and workmanship as the V130. This includes, among other characteristics, that the fan is operated by a high-quality and powerful electric motor which is well-protected against dust.

The AirMaster fans of the V130/VC130 series are usually mounted in the gable for tunnel ventilation. Their metal housing has a long-lasting zinc-aluminium coating. The specially shaped blades are made of glass-fibre reinforced plastic. Air guiderails on every blade ensure a large air capacity combined with a low resistance and thus low energy consumption. The air flow opens the shutters, which are then kept open by means of a balancing weight. When the fan stops, the shutters close automatically and are locked magnetically. Fans with cone require even less power while also having a higher air performance. They need slightly more space in the gable.
