Helps provide respiratory protection against airborne contaminants in harsh, dirty environments. Facepiece is designed to help promote comfort, durability and stability with a firm, lightly textured silicone faceseal and strong body construction. Helps provide respiratory protection at concentrations up to 10 x the Permissible Exposure Limit (PEL) when respirator is properly fitted. Sleek, overmolded/low-profile design helps to give a wide field of view that better suits compact work spaces and simplifies cleaning. Resilient silicone face seal offers an extended facepiece life, even keeping its shape in high-heat environments. Facepiece offers numerous other comfort features including a special valve cover that helps to direct exhaled breath and moisture downward and 3M’s proprietary Cool Flow™ Valve that helps to make breathing easier by reducing heat and moisture. Made to fit securely and comfortably on the head, the facepiece comes with an adjustable head harness assembly featuring polyester/spandex straps that stretch and conform. Facepiece is compatible with all 3M™ bayonet-style filters and cartridges to help provide respiratory protection against a variety of gases, vapors and particulate hazards according to NIOSH approvals. The 6500QL Series features a proprietary Quick Latch design offering an easy, one-hand touch drop-down mechanism for putting the facepiece on and off while moving in and out of contaminated areas. NIOSH/MSHA Approved.
