Master Pneumatic’s breathing air assemblies are designed with 2 and 4 drops to provide breathing air for up to 4 workers. A Breathing Air assembly can allow end users to achieve "grade D" breathing air as defined by the Compressed Gas Association's commodity specification: G-7.1 (www.cganet.com).
The general purpose filter in an assembly removes gross contaminants while the coalescing filter removes oil mists, aerosols and minute particles. The adsorbing filter effectively eliminates odors from freons, alchohols, esters, keytones and up to 99 percent of most hydrocarbons. The CO monitor is designed to detect and alert user to the presence of CO if the level is 10 ppm or greater as stated in OSHA title 29 section 1910.134(D)(1)&(2) ANSI/CGA standard G-7.1
This assembly does not remove carbon monoxide or convert CO to CO2, or remove other toxic gases.
