Choosing the right size of fan does not depend only on the size of the room. It is also important to consider the layout of the room, where in the room people to tend to congregate, where the airflow is most required and how high the ceiling is.
Our smaller diameter fans (1.2m and 1.4m) produce mainly downdraft within a radius extending up to a metre beyond the blade tips. Our larger fans (1.6m and 1.8m), produce greater side-draft and less direct down-draft. Therefore, when selecting a fan, it is important to decide whether a direct cooling draft is required or whether gentle air circulation is the more important factor.
Given below is a sizing chart that can be used as a rough guide to selecting the size fan. Please feel free however to contact us if you would like to discuss your specific situation or room layout.
