Allegro 9874-MR Multi-Regulator Air Filtration Panel- 4 Port

Works to filter impurities and hydrocarbons from an air compressor in order to convert air to breathable air. Integrated CO Monitor meets OSHA requirements for continuous monitoring of carbon monoxide levels. Unique design of this panel allows each regulator to be individually adjusted at different pressure settings, allowing as well, separate outlets for air tools. Viewing window on the case allows monitoring of pressure gauges. 16 gauge steel stand for support is included as well as all brass plumbing with quick-disconnect Hansen couplers. Allegro air filtration panels filter impurities and hydrocarbons from an air compressor to convert to breathable air. A CO monitor is integrated to meet OSHA requirements for continuous monitoring of carbon monoxide levels. The panels provide 60 CFM (101.94 m3/hr) or 100 CFM (169.9 m3/hr) of air within a 5-125 PSI (.34-8.62 bar) range.* (fittings used for breathing air must not be compatible with other plant/tool air fittings, contact Technical Support for details).
