Replacement belt for 3M Adflo Powered Air Purifying Respirator (PAPR).The unique belt design has a solid leather front, cut narrow to allow the welder to bend forward easily. Along the welder’s sides, the leather becomes wider, with large ventilation holes for maximum breathability. The turbo unit securely attaches to, and is nestled between, the two plastic arms of the belt so the turbo’s weight is evenly distributed across the entire lower back and upper hips. The plastic arms are vertically rigid but with pleats so the welder can move and turn with freedom.
