Specific Systems - Packed Bed Chemical Scrubbers (PCBS)

Specific Systems ChemPac PBCS units sit outside the protected area and mate perfectly to fully redundant dual InPac systems using a short piece of duct work.

Like our built-in option Specific Systems Packed Bed Chemical Scrubber uses a 4 section filtration setup, containing:

• A bank of standard Farr 30/30 pre-filters
• Two 12" deep beds of chemical filter media
• High efficiency final filter bank.

Each system is manufactured using 16 gauge 316 stainless steel.

Typically, the scrubber employs 1600 pounds of carbon filtration along with a corrosion resistant media to protect against corrosive airborne agents. However, special considerations may require other types of filtration media, with one filter bed for each of the types of media.

100% redundant spark-proof fans force between 1600 and 3600 CFM through the filtration system, using 5–10HP TEFC motors. Static pressure of the system is approximately 9.5" when full of media.

Further, most chemical filtration systems with separate HVAC require use of an exhaust damper to regulate pressure inside the building. Using this technique wastes the air that is filtered by the chemical scrubber. The Specific Systems PBCS includes a return air duct that continues filtering cleaner air, thereby maximizing the effectiveness of the filtration system, and requiring less frequent changes of the filtration media.

• Easy access to install and remove filtration media
• Rain louvers
• Return air duct to maintain cleaner air with less waste
• Quick installation via ductwork and integrated electrical conduit
• Return air allows for greater efficiency, cleaner air, and increased long-term savings
• Up to two different chemical filtration media types available in each system
