Martech’s Personal Air Breathing Unit is a complete filtration and monitoring system designed to be worn on your waist. It complies with OSHA 29CFR1910.134 Respiratory Protection regulation for Grade “D” Breathable Air. The single-line hose design improves users’ efficiency and makes it easy to use wherever clean, compressed air is available. It includes a breathing air filter to remove oil vapors, hydrocarbons, toxins and odors commonly found in compressed air systems. The built-in carbon monoxide monitor continuously monitors the filtered air for compliance with current OSHA standards. The monitor is equipped with both audible and visual alarms, and operates on a 9-volt alkaline battery. An integral pressure regulator with gauge is provided to set the pressure for a NIOSH-approved mask or hood. Also, a 54-inch tool hose is provided, prior to the unit, to complete the assembly for a single-line hose system. It can be used with any appropriate NIOSH-approved mask or hood – when the use of an air-supplied respirator is required – to provide proper protection from airborne contaminants. It should not be used in atmospheres that are immediately dangerous to life or health (IDLH).
