Title (EN) FOCUSSED VENTILATION PROCEDURE FOR A WORK SPOT AND APPARATUS USED IN THE PROCEDURE
(FR) PROCEDE ET APPAREIL DE VENTILATION FOCALISEE D'UNE STATION DE TRAVAIL
Abstract: front page image
(EN)The present invention concerns a focussed ventilation procedure of a work spot. In the procedure, focussed suction is focussed on the source of impurities of the work spot and/or on the source of excess heat, and the operation of the focussed suction is assisted with the air blown from a wide surface area at a low speed from an incoming air means (12; 14). The invention also concerns an apparatus used in the procedure.
(FR)Selon un procédé de ventilation focalisée d'une station de travail, on applique une aspiration focalisée sur la source d'impuretés et/ou de chaleur excessive dans la station de travail. L'aspiration focalisée est facilitée par un dispositif d'amenée d'air (12; 14) qui souffle de l'air par une large surface à une vitesse réduite. L'invention concerne également un appareil d'application du procédé.
