Packed Bed System (PBS)
PureAir® Packed Bed System (PBS) is a complete self contained, horizontal airflow unit.
This deep bed scrubber provides continuous high efficiency air purification for contaminated air streams ranging in volume from 200 to 5,600 CFM.
The PBS comes in either blow-through or draw-through configurations. Standard construction is with stainless steel.

LOCATION: Portland, Oregon
EQUIPMENT/MEDIA USED: 2 – Packed Bed System (PBS-709) and CPS Blend media
PROBLEM: The downtown park, a heavily used event area, is affected with odorous air, which cannot be removed without installing air filtration systems in an underground vault accessible only through a small service hatch.
SOLUTION: PureAir® custom engineered two PBS systems, cut each system into 12 precise pieces, lowered them by crane through the hatch, maneuvered each piece down a narrow corridor, and reassembled both systems in the vault over the course of two to three weeks.
LOCATION: Spokane, Washington
EQUIPMENT/MEDIA USED: Packed Bed System (PBS) and Sulphasorb XL™ media and CPS Blend media
PROBLEM: Processing raw sewage releases H2S, VOCs, mercaptans, and sulfur compounds into the air.
SOLUTION: PureAir® custom engineered multiple PBS systems (sizes ranged from PBS-404 to PBS-809) with two media beds in each for Sulphasorb XLTM media and CPS Blend media.
