A low speed cooling fan (100) that is designed to cool individuals located in large industrial buildings. A fan with a diameter between 15 to 40 feet consisting of a plurality of blades (316), with each in the shape of a tapered airfoil, is driven by an electric motor (304) to produce a very large slowly moving column of air. The moving column of air creates a uniformly gentle circulatory airflow pattern (200) throughout the interior of the building thus promoting the natural evaporative cooling process of the human body at all locations inside the building.

Ce ventilateur de refroidissement tournant à petite vitesse est prévu pour rafraîchir des personnes se trouvant dans de vastes locaux industriels. Ce ventilateur, dont le diamètre est compris entre 15 et 40 pieds, est constitué de plusieurs pales, ayant chacune un profil aérodynamique effilé. Il est entraîné par un moteur électrique permettant de créer une très grande colonne d'air se déplaçant lentement. Le déplacement de la colonne d'air engendre une veine d'air uniforme à circulation modérée à l'intérieur de tout le local, facilitant, de la sorte, un refroidissement naturel par évaporation d'eau du corps des personnes se trouvant dans le local.
