Particulate/Coalescing Filters

  • PSB Air and Gas filters are replaceable element design and efficiently remove contaminants including:

Entrained water aerosols

Entrained oil aerosols

Solid particulates

  • Coalescing (aka: Prefilters) are commonly located at inlet of desiccant/adsorbent beds. The coalescing action removes entrained liquids to protect the desiccant bed from being contaminated and overloaded.

  • Particulate (aka: Afterfilters) are commonly located at the exit of desiccant/adsorbent beds. The filter removes solid particles to protect downstream equipment.
