Greenhouse HAFL fan 450mm

Vortex Horizontal air stirring fans – Stainless steel 450mm body

The Redpath Horizontal air flow fans have been specifically designed to be corrosion resistant within a greenhouse or animal shelter environment which can expose fans to high humidity and be corrosive due to operational sprays, fertilsiers etc that are often present.
The Redpath Vortex horizontal air flow fan features a stainless steel body for superior corrosion resistance and for extra safety the fan includes safety grilles on both the intake side and the exhaust side of the fan.
Four suspension hanger eye hooks are included
Two chains and carabina clips are also included.
The impellor is statically balanced and is also corrosion proof being made from injection mould plastic. This also assist the fan to operate at a quieter noise output compared to metal style impellors.

A single phase motors 240/230v. CFM rating is 3500-4000cfm air flow nominal,  Air throw is typically 25 metres within a standard 3.5m pole height greenhouse.
In single span greenhouses locate a fan at one end and then every 25metres facing in same direction. In multi-span buildings face the fans all in one direction in one span and then the opposite direction in the very next span to help create a circulation effect within the building.
Vortex fans are popular for the prevention of stagnant air occurring within buildings and thus help prevent associated diseases or infections that can occur within closed environments that have a high planting or animal intensivity.
Note: Always use a qualified electrician to connect and appropriate RCD protection to suit individual application. Some sites have a low voltage supply or varaible voltage supply please fit a voltage regulator and thermal overload in these situations.

Benefits of Redpath 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
