Compliance with the OSHA requirement for Grade “D” Breathable Air can be accomplished with the use of a Quality Air Breathing System – Model 50 SL, manufactured by Martech Services Company. When used properly, a Model 50 Single Line Hose System will work with the existing compressed air supply. The Model 50 SL System will provide Grade “D” Breathable Air for a NIOSH-approved respirator, and with the provided 54-inch tool air hose, it will supply air for a spray gun, all via the included single-line hose assembly. It is available with 35- and 50-foot single-line hose assemblies, and will work with the existing compressed air supply. The four-stage filtration filters the air, and the on-board carbon monoxide monitor continuously monitors the air quality for compliance with current OSHA standards. With the ever-increasing awareness and need to properly protect workers while working in contaminated air spaces, systems are available that are designed for multiple users at the same time. Accessories can even increase or decrease the temperature of the air supply for improved user comfort. Each system is backed by a one-year warranty and supported by a toll-free sales and service telephone support staff.
