AirMaster fans of the V130/VC130 series are mostly 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 guide-rails on every blade ensure a high air performance combined with low resistance and thus low energy consumption.
The airflow opens the shutters, which are then kept open using 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, which means 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.
