Grade D Air Filtration Panel by Draeger Safety


Categories: ,

The Draeger Grade D Air Filtration Panel is designed to provide Grade D breathing air to workers with supplied air lines in hazardous of IDLH environments. Capable of supplying 50 cfm or 100 cfm of continuous positive pressure air, the air panel uses a plant or mobile compressor as the primary air supply. The three stage filtering system effectively removes solid particles, liquid, hydrocarbon vapors and odor from the supplied air. To meet federal, state and local regulations, a carbon monoxide monitor continuously checks CO levels. NIOSH Approved for use with up to 300 feet of hose with Draeger supplied air respirators (SARs).


  • Grade D breathing air meeting or exceeding OSHA requirements
  • CO monitor with internal RFI/EMI filters built into the circuitry to eliminate radio interference
