Redpath “VORTEX” Circulation Fans
How do VORTEX fans work?
The very simple principle of Horizontal air flow is firstly to invigorate the internal environment and secondly to circulate, mix and stabilize the temperature regime. In still air, warm air rises and will quickly pool in the highest point of the roof, however this is very easily prevented by causing some gentle air motion. This air motion needs only to be very slight but thoroughly throughout the entire house.
The third but most important benefit is the reduction in fungal sprays required as a result of installing Vortex Fans.
The reason for this is that the gentle air movement displaces transpiration moisture from the foliage and lowers the dew point at the leaf surface. The combination of air movement and drier foliage radically inhibits fungal growth of all kinds and may substantially reduce the need to use fungicides.
Benefits of using VORTEX fans
- Reduced air stratification (temperature layers)
- Improved C02 distribution
- Helps prevent “calm” pockets of air within the environment
- Balance out humidity levels
- Reduced fungal disease in plants and respiratory disease in animals
Installation Suggestions
Suspend the units from chain or stout cord and attach to the roof at strong supports longer than the actual fan. This will brace the fan and prevent any swinging or sway induced by the airflow.
Use two fans per bay on single span houses. For multi-bay structures use one fan per bay and site each adjacent fan at opposite ends of the house. In longer houses than 35-40 metres we would suggest a additional fan units be situated every 30-35m own the bay to assist air movement for the full length.
