The 3M DT-4046E is a combination filter for conditions where gases, vapours and airborne particles may be present together. It combines gas, vapour and particle filtration in a single unit.
It works on both negative-pressure respirators and powered air systems, so one filter type can serve across compatible 3M equipment on site.
Key features
- Protects against organic and inorganic gases and vapours
- Protects against acid gases and vapours
- Protects against mercury, ammonia and organic ammonia derivatives
- Filters many kinds of particles, micro-organisms and enzymes
- Fits certain 3M half and full-face tight-fitting respirators used in negative-pressure mode
