Camfil Farr’s PB Pre-filter Housings:
    •    Are manufactured of the same materials as prime containment components.
    •    Are continuously welded at all pressure barrier joints.
    •    Are reinforced to be capable of withstanding up to 15” w.g. positive or negative pressure.
    •    Have hardware constructed of 300 Series stainless steel. The door knobs are cast aluminium to prevent galling of male stainless steel threads (according to DOE HDBK-1169-2003, 6.2.2)
    •    Include a bagging ring to facilitate a safe-change procedure to protect filter change-out personnel.
    •    Have doors that include a silicone gasket for a positive seal during system operation.
All Camfil Farr PB Pre-filter Housings are manufactured to industry-standard recommended practices and evaluation criteria as are the prime containment components.
The PB Series 200 will accept 2”, 4” or 6” deep ASHRAE grade pre-filters. The PB Series 212 will allow installation of a 2” deep pre-filter and a 12” deep secondary filter.
