The system filters compressor air to provide respirator users with Grade-D quality air. The first stage element filters bulk water and particulate, the second stage coalescing filter removes atomized oils and ultra-fine particulate, and the third stage removes organic vapors and odors. Filter change indicators are standard on all three filtration stages. Filtration efficiency is 99.99% @ .01 microns. A built-in carbon monoxide monitor operates on 115 VAC, or 8-16 VDC for continuous detection. A high intensity audible alarm and light signals the workers of high CO content in their breathing air. A 115 VAC electrical conduit box is provided as standard to provide AC power in and connection for AC powered remote alarms. Filtration components are mounted on powder coated steel panel. Features 100 CFM (123 CFM flow capacity) CO carbon monoxide monitor 99.99 percent filtration efficiency @ .01 microns 4 couplings or NPT outlet Integrated carbon monoxide (CO) monitor uses 115 Volts AC or 8 to 16 Volts DC for continuous detection Audible high intensity alarm & light will signal workers to high CO in breathing air supply All portable and fixed breathing air filtration systems meet or exceed OSHA 1910.134, Canadian Z180.1 Breathing Air Standards and British Standard BS-EN 12021:1999 “RESPIRATORY PROTECTIVE DEVICES” All filtration units are designed to flow the NIOSH maximum capacity per worker Air Systems provides at NO CHARGE your first lab certified air quality test of your new breathing air filtration device Please specify 1/4” Hansen style or Schrader style fittings when ordering.
