Installation suggestions
In a greenhouse situation, to generate a circular horizontal air movement, situate the unit above head height and approximately 3-10 metres in from the gable end wall and 3-8 metres or one-third from the side wall. (See Diagram A).
This will provide a gentle drift down one side across the end and back up the opposite side where it will be recirculated.
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 additional fan units be situated every 30-35m along the bay to assist air movement for the full length.
