Casing: The fan casing consists of galvanized sheet steel, the inside construction is made of high-quality polypropylene for a high corrosion resistance.


Blade and blade hub: The vane has 3 or 5 specially shaped blades made of glass-fibre reinforced plastic. Air guide-rails on every blade ensure a large air capacity combined with a low resistance and thus low energy consumption. The blade hub is made of aluminium. The 5-blade Fanmaster is often installed in barns with a high back pressure (cage houses with tunnel ventilation, use of exhaust air treatment systems). The 5-blade fans, can used up to pressures of 80Pa.


Shutters: The shutters are opened by the air flow and then kept open by means of a balancing weight. When the fan stops, the shutters close.


V-belt gearing: The V-belt pulley is made of aluminium and is manufactured as one piece together with the blade hub by die-casting. The V-belt is pretensioned, further tensioning is therefore not necessary.


Electric motors: We use high-quality motors with a large voltage range (motor protection IP 55, approved for UL/CSA). The motor is completely closed; a separate cooling fan is not necessary. This means there is no danger of dust entering the motor or overheating of the motor
