High air performance, low costs
AirMaster fans of the V130/VC130 series are mostly mounted in the gable for tunnel ventilation. Their metal housing has a longlasting zinc-aluminium coating. The specially shaped blades are made of glass-fibre reinforced plastic. Air guide-rails on every blade ensure a high air performance 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. The V-belt pulley is made of aluminium and is manufactured as one piece together with the blade hub by diecasting. The V-belt is pre-tensioned, i.e. a belt tensioner is not necessary.
We use high-quality IE3 motors with a large voltage range (motor protection IP 55). The motors are completely closed; a separate cooling fan is not necessary. This means that there is no danger of dust entering the motor, protecting it from overheating
-optimised aerodynamics at the air admission and air exit sides for a high air performance;
-specially shaped blades ensure optimum operation, thus reducing electricity costs;
-low noise level;
-the air flow pressure opens the shutters, which stay open thanks to balancing weights, i.e. there is little air resistance;
-stable and robust design;
-easy to install without external assistance.
