Temporary Aluminum Partitions

A new temporary partitioning system is described which more effectively controls the migration of dust particles into clean product manufacturing and test areas during in-plant construction.

Currently approved contamination barriers used to enclose in-plant construction work consist of a layer of fire-retardant plastic sheeting stapled on to a frame of 2x4 wooden studs. The plastic sheeting, although fire retardant, is made with a coating that readily flakes off and creates air-borne dust particles. Also, the construction grade wood framing also generates tiny particles of contamination, and generally the barrier is only used once. Because tight fits between adjoining sections is difficult to achieve, a cross flow of air between the dirty work area and the clean room results. With the advent of sub-micron technology and the drive to create ever cleaner product environments, more effective in-plant construction barriers are needed.

As an alternative to current barrier techniques, a temporary partition system consisting of an anodized aluminum sheet or skin is riveted and taped on to a frame of 1-1/2-inch square tubing. The new system also includes threaded pedestal feet for making height adjustments to suit field conditions, adjustable return air skirts for controlling clean room flow and positive pressure, panels with doors to allow access in and out of construction areas, several different sizes including one-, two-, three- and four...
