TRI-LOCK OPERATION AND MAINTENANCE
INSTALLABLE FILTERS
Tri-Lock FS and GS accommodate different Tri-Pure™ HEPA and
Tri-Dim ASHRAE filters. Standard versions of the housings
accommodate 24” x 24” x 11½”-deep HEPA filters with DOP
efficiencies of 95%, 99.97% or 99.99% @ 0.3 μm.
See filter manufacturer’s individual filter efficiency requirements.
FLUID SEAL DESIGN CONCEPT
The filter-to-housing fluid seal is effected by means of a continuous
perimeter knife-edge on the interior of the housing, which mates
into the gel-filled perimeter channel on the face of the filter. The
hand-operated locking mechanism guides and secures the filter
into the knife-edge—penetrating the gel and forming a positive seal
on the filter face.
DESCRIPTION OF FLUID-SEAL FILTER LOCKING
SYSTEM
The fluid-seal Tri-Lock FS housing has a filter-locking arm in each
tier to operate the replaceable filter-locking mechanism. By
operating the internal filter-locking arm, the filter is engaged or
disengaged from the housing knife-edge (internal-sealing frame).
The filter-locking arm and access door operate in such a manner
that minimizes the possibility of the door being closed until the
filters are correctly sealed in the housing and sealed to the mounting
frame.
