The Quality Air Breathing System complies with the OSHA requirement for Grade “D” Breathable Air. When placed near the point of use, it 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. Complete systems designed to fit the user’s facilities and needs are also available. Systems are capable of supporting two or more persons at the same time. Visit www.breathingsystems.com.
