Abstract
An improved air diffusion panel, and method of construction and use, is provided which is particularly suitable for use in clean and ultra-clean environments, such as clean rooms and mini-environments facilities. The preferred diffusion panel of the present invention includes a diffusion membrane of a continuous mass of porous polytetrafluoroethylene bonded to one or more support screens of polymer mesh. The composite membrane and screens are mounted in a unique frame which eases the time and effort required for construction of the panels and which can be mounted to reduce vibration of the panel and leakage around its edges. This improved air diffusion panel also significantly filters small and sub-micron particles, resists chemical attack, and blocks liquid droplets.
