Page 4: Introduction To Bag-In/Bag-Out Housings
Introduction To Bag-In/Bag-Out Housings Camfil’s line of Bag-In/Bag-Out housings are “containment” design, side loading filter housing used for critical applications. These filter housings have been designed to meet the air filtration needs of industries and research facilities that handle dangerous or toxic, biological, radiological or carcinogenic materials. To minimize exposure to these harmful contaminates, while replacing and handling contaminated filters, the housing incorporates a heavy duty plastic bag covered access port. - Page 5 -Place Testing of filters or adsorbers. These test sections have proven to perform as good or better than the conventional method of in-place testing. Camfil has designed and qualified four (4) types of test sections (upstream, combination, downstream and accurate scan) for any need. The upstream test section housing design allows you to disperse a challenge agent uniformly across the filter/adsorber face so that the complete filter/adsorber is challenged.

1. Check for correct model number, quantity, type, and size of media. 2. Unpack the filter/adsorber in accordance with Camfil’s recommended instructions. Rest filter on floor and cut open taped seam with utility blade (set blade to 1/8” max.). Open box and bag(s) protecting filter/adsorber. - Page 7 5. To gain access to the inside of the filtration housing, remove the housing access doorknobs by turning counter-clockwise (for housings equipped with swivel latches: do not remove doorknobs; loosen and swivel door bolt out from door corner retainer). Pull the access door straight towards you to remove. 6.
- Page 8 8. Once the filter(s)/adsorber(s) is loaded inside the housing, slowly close the locking mechanism handle by pushing the locking mechanism handle towards the locking handle latch (see illustrations and pictures on this page and pictures on next page). This allows the fluid seal channel on the filter/ adsorber to seal with the knife-edge sealing surface.
- Page 9 Locking handle should close fairly easily, until approximately 1” before the locking handle latch. Then moderate pressure should be ap- plied to lock handle. Warning: Do not force the locking handle to close. See page 17 if locking handle needs adjustment.

Page 10: Filter Change-Out
FILTER CHANGE-OUT (Replacing Contaminated Filters Or Adsorbers) Bag-In/Bag-Out Concept Consult your safety officer before beginning filter change-out, to assure all proper procedures are followed for your application. Note: Filtration housings that contain more than one filter/adsorber are equipped with filter removal rods. Filtration housings containing multiple prefilters also are equipped with removal rods. - Page 11 A Camfil change-out shelf can assist in making the change-out easier (as shown in picture, see Spare Parts...
- Page 12 7. Place a new change-out bag over a new filter/ adsorber to be installed (see Installation of New Filter for proper unpackaging and preparations). Make sure the new filter/ adsorber is orientated so that when placing inside of the filtration housing the filter clips will be on the top and bottom of the filter (see pictures, page 7).

The in-place leak test shows an unacceptable penetration of challenge agent. 2. Filtration System The filtration system is the containment structure built by Camfil. This structure may be a single housing, or a complete filter train (consisting of multiple, adjoining housings), depending on the scope of the contract. - Page 15 If the gasket on the access door becomes damaged, it can be replaced with new gasket by the user. You may purchase replacement gasket from Camfil (see Spare Parts and Accessories, page 18). The following steps should be taken to replace a door gasket: 1.

5. Install replacement locking mechanisms and secure with 3/8” locknuts which were removed from replaced locking mechanism. Note: Before replacing new locking mechanism, be sure the nylon washers are around studs. Tighten 3/8” locknuts securing locking trays to housing, then loosen the locknuts 1/4 turn (This step is critical to allow free movement of the locking tray). -
