The present invention provides a portable protective system for protecting a wearer, and for protecting the environment about the wearer. The protective system includes a face shield coupled with a head cradle for supporting the face shield on the wearer's head. The face shield and a wearer's face substantially define a breathing zone charged by a battery-powered blower carried on the head cradle. A bag-like inlet filter element encompasses the blower to provide filtered air to the breathing zone, and an outlet filter element is operably associated with the face shield.

La présente invention concerne un système de protection portable permettant de protéger un utilisateur et de protéger l'environnement de l'utilisateur. Le système de protection comprend une visière couplée à une coiffe pour retenir la visière sur la tête de l'utilisateur. La visière et le visage de l'utilisateur définissent sensiblement une zone de respiration chargée par un ventilateur alimenté par piles situé sur la coiffe. Un élément de filtre d'admission en forme de sac entoure le ventilateur pour alimenter la zone de respiration en air filtré et un élément de filtre de sortie est fonctionnellement associé à la visière.
