Abstract
A facepiece charging device comprising a receptacle system, an electrostatic charging system, and a support structure. The receptacle system is configured to detachably receive and secure a facepiece. The electrostatic charging system is configured to transfer an electrostatic charge to the facepiece when energized. The support structure has a moveable guide system coupled to at least one of the receptacle system or the electrostatic charging system. The moveable guide system has at least an engaged position where the receptacle system is adjacent the electrostatic charging system to electrostatically charge the facepiece and a disengaged position where the receptacle system is spaced from the electrostatic charging system.
