When placed near the point of use, the Quality Air Breathing System will work with the existing compressed air supply. The four-stage filtration filters the air, and the on-board carbon monoxide monitor continuously oversees the air quality for compliance with OSHA standards. Compliant with the OSHA requirement for Grade “D” Breathable Air, the system is designed for multiple users and ease of use to properly protect workers. The systems are even capable of supporting two or more people at the same time. Accessories can increase or decrease the temperature of the air supply for user comfort.
