Salisbury by Honeywell's revolutionary AS1200HAT is a weight balancing arc flash protection face shield, that stows in a balanced, compact position, centered over the top of the hard hat when not needed. The AS1200HAT has an ATPV rating of 12 cal/sq-cm and utilizes nanotechnology to provide a more transparent window for improved visibility. The shield/window is designed to be easily replaced without tools. The face shield unit includes ventilation ribs that allow a natural convection air flow through the top of the face shield. This reduces fogging of the visor, lowers CO2 levels and improves comfort for the user.
