- Suitable for barns with tunnel ventilation if the housing equipment causes high resistance
- Produces a high airflow rate where there is much resistance
- Stable connection between the hub and the six blades
The AirMaster V140 and VC140 fans produce a high airflow rate where there is much resistance. Therefore, they are a good choice in barns with tunnel ventilation if the housing equipment causes high resistance and thus makes an unobstructed airflow impossible.
The V140 and the VC140 fans meet the same exacting requirements regarding quality of the material, aerodynamics and workmanship as the V130 / VC130 fans. This includes, among other characteristics, that the fan is operated by a high-quality and powerful IE3 motor which is well-protected against dust.
The connection between the hub and the six blades is very stable and ensures the secure running of the fan, even at a negative pressure of 100 Pa or higher. The airflow opens the shutters, similar to the V130 /VC130. The shutters are then kept open using a balancing weight. When the fan stops, the shutters close and are locked magnetically.
