Des parties à étage dans le sens de la hauteur et le sens de l'épaisseur sont formées de façon à faciliter la génération de la turbulence et des guides sont situés sur les parois externes des pales de la soufflante à turbulence, de sorte que l'air comprenant les sources de pollution ou analogue et partiellement dispersé par la force de rotation des pales est introduit dans le logement. Le ventilateur soufflant du type à turbulence selon la présente invention comprend : un logement de forme creuse possédant un diamètre interne plus grand au niveau d'une partie extrémité latérale que de l'autre partie extrémité latérale ; un moteur situé sur l'intérieur du logement ; un arbre de rotation cylindrique situé sur le moteur ; la soufflante à turbulence comprenant une plaque de rotation, située sur l'arbre de rotation de façon à tourner et une pluralité de pales disposées le long de la surface périphérique externe de la plaque de rotation et fixées dans un état dressé ; une ouverture évasée entourant la soufflante à turbulence au niveau de la partie inférieure de celle-ci ; et un ventilateur d'extraction, situé sur l'arbre de rotation de façon à tourner, est disposé au niveau de la partie inférieure de l'ouverture évasée et est formé à partir de l'association d'une pluralité de pales individuelles qui sont orientées selon un angle prédéfini par rapport à une direction radiale.
