AS2000HAT is a Weight Balancing Arc Flash Protection Face Shield. The shield stows in a balanced, compact position, centered over the top of the hard hat when not in use. The AS2000HAT has an ATPV rating of 20 cal/cm2 and utilizes nanotechnology to provide a clearer, more transparent window for improved visibility. 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.
