TRI-LOCK OPERATION AND MAINTENANCE
ABOUT THE PRODUCT
Tri-Dim’s line of Tri-Lock BG/BF bag-in/bag-out filter housings for
fluid or gasket seal primary filters are side loading filter housings
which have been designed to meet the air filtration needs of
industries and research facilities that handle dangerous, toxic,
biological or carcinogenic material. To minimize exposure to this
harmful contamination while replacing and handling dirty filters, the
housing incorporates a ribbed bag-in/bag-out ring over which a
heavy-duty plastic bag is attached (see picture below).
Once the initial filters are installed and the first bag attached, all
filters – both dirty and new, are handled through the bag using the
procedures described in detail throughout this manual. Depending
upon the user’s requirements, the housing may have an assortment
of filter arrangements, including prefilters, HEPA filters and other
type filter media. No matter what types of filters are contained
within the housing, the filter change out procedure is the same.
Note:
Filter change out is incomplete unless the new filters have
been sealed to the housing frame and an in-place leak test has been
performed.
