Standard compressed air usually is contaminated with oil, water, dirt, rust and often deadly (CO) carbon monoxide. Systems with four or five stages of purification will remove or reduce these contaminates and continually monitors the carbon monoxide level of the purified air to QSHA Grade D breathing air specifications.

Types of applications to use breathing air purification systems: painting, sand blasting, insulating, welding, toxic spills, asbestos abatement, tank cleaning/inspection, sewer work/manholes and foundries.
