DFM 4 Media





Paint Booth Diffusion Media

Diffusion Media - Downdraft

This precise blend of synthetic fiber size, bonding agents and unique adhesive system, which coats each fiber, results in a uniform, dense, high quality filtration media.

DFM 4 Filter Media

  • Typical application is in downdraft booths as a ceiling filter.
  • DFM 4 media becomes the final filtration barrier preventing damaging particles from entering the paint booth environment.
  • The uniform density of the DFM 4 media acts as a diffuser ensuring an even laminar air flow throughout the booth.
