A clean room ceiling grid system having a detent means for loading filter panels into ceiling grids from a clean room. The system is operable to permit removal of the filter panels by use of a filter panel removing tool. More particularly, this clean room ceiling grid system requires no plenum space use above the grid members for either installation or removal of filter panels. The system also includes means for hermetically sealing the interface of connected ceiling grid members and means for substantially laminar flow of filtered air in clean rooms.

A system for providing airtight/particle tight hermetic sealing of a plurality of interfacing grid members, each of said grid members having vertically oriented and horizontally oriented wall portions defining an internal chamber, and each of said grid members comprising: (a) an aperture extending through a wall portion of said grid member, said aperture permitting infusion of caulking compound into said grid member internal chamber proximate a first end of said grid member designed for interface with another grid member; (b) a plurality of protrusions located on said first end of said grid member; said protrusions permitting caulking compound leakage past said interface; (c) caulking stop means located within said grid member internal chamber; said caulking stop means permitting a predetermined volume of caulking compound to be infused into said internal chamber; (d) whereby when said predetermined volume of caulking compound is infused into said internal chamber through said aperture, an amount of caulking compound is urged out of said internal chamber past said protrusions; and, (e) whereby said caulking compound leakage seals said interface between said plurality of grid members.
