Laser Cutter Exhaust Filter Box

PCU (pollution control unit)


  • 4“ inlet at top
  • Side-by-side 20×16 furnace filters
  • Screen bed of activated charcoal granules
  • 4” outlet at bottom[]=laser&s[]=exhaust#verison_52_-_lenox_mar_2017_-_mar_2017


Could not pull suction through it.
Drawers needed latches or gaskets. MDF panels were too leaky even after painting them with glue and caulking the joints.
Disassembled and used for scrap on other projects.
