Clean room air filtration systems consist of very fine particulate filters secured and sealed to a framing structure. Present systems rely on gaskets and caulking compounds to seal the framing system to the perimeter walls. A fluid-sealed design is described which overcomes the reliability problems of the present design. The present system often yields an inadequate air seal against sub micron particles due to flaws in construction material and installation procedures as well as long term failures due to wall movement. This system (Fig. 1) depends on quality joint seals 1 between skirt 2 and wall 3 and skirt to skirt 4. It also depends on quality gaskets around nails or studs 6.
