Compressed air, commonly called Industry’s fourth utility, is the most common utility used in a typical industrial facility. Compressed air is used in more than 70 percent of all manufacturing activities including supplying breathing air to personnel using supplied air respirators. Hazardous breathing conditions exist in many routine industrial operations, such as chemical manufacturing, hospitals, sand blasting, paint spraying, industrial cleaning, and welding. In these and other operations that introduce contaminants into the workplace, supplied-air respirators, air filtration systems and carbon monoxide monitors are frequently used for worker protection.


ENMET provides compressed airline monitoring and filtration systems for many applications including monitoring and filtering supplied breathing air, monitoring hospital compressed air systems, and monitoring compressed air in manufacturing processes. Our compressed airline CO monitors are designed to meet OSHA monitoring requirements for Grade D breathing air and NFPA 99 “Medical Air System Guidelines”. Products include our popular CO-GUARD respiratory airline CO monitor. Our most advanced airline monitors, MedAir 2200 and ProAir 2200, are UL and CSA certified and can monitor up to four points of detection including CO, CO2, O2, dew point, VOCs, trace hydrocarbons and an array of other hazardous gases that may be present in compressed air. Our AirGuard, a next-gen portable breathing air filtration system, provides comprehensive data log records and uses an audio alarm and large external color display to communicate warnings, threats and data collection. It integrates a three-stage filter system CO, differential Dew Point and CFM flow sensors for both safety and breathing air comfort.  Contact ENMET today and find out more about our complete line of compressed air monitoring and filtration equipment.
