Air filters are used to remove objects, particles, dust, and pollutants from the air and clean it. Not only do filters clean the air in living spaces, but they also perform the important task of preserving human safety by preventing the release of hazardous substances in factories. Air filters maintain the air environments in places such as factory cleanrooms used for metalworking and semiconductors that require a high quality of purity, and they reduce the possibility of contamination from the introduction of impurities.

A clean room is disclosed which has a capability of being divided into separate work areas of predetermined size, and with the separate work areas being effectively isolated from each other to prevent cross contamination. The clean room comprises a filter bank composed of a supporting latticework and a plurality of filters, with the latticework being supported by tie rods which extend through the latticework. A plurality of wall panels are supported below the latticework, and are attached directy to the tie rods so that the weight of the wall panels is not borne directly by the tie rods and by the latticework. Also, the latticework and wall panels are effectively isolated from external vibrations, by means of a flexible sealing strip between the periphery of the latticework and the bounding side walls of the clean room, and by the fact that the wall panels are free of any connection with the floor of the clean room.
In U.S. Pat. No. 3,486,311 to Allan, which is commonly owned with the present invention, there is disclosed a filter bank assembly for a vertical laminar flow clean room, and which comprises a horizontally suspended rectangular latticework composed of interconnected U-shaped channels, and which sealably support the filters thereupon. It has also been proposed to modify the clean room of the type shown in the Allan patent by bolting depending temporary walls to the latticework to provide separated work areas within the room and which are of variable configuration. However, this has not been found to be totally satisfactory, since the latticework is of a relatively lightweight metallic construction, and the bolting of relatively heavy wall panels to the latticework tends to bow the latticework, thereby tending to destroy the seal between the latticework and the filters.
These and other objects and advantages of the present invention are achieved in the embodiments illustrated herein by the provision of a novel clean room which includes a top wall, a bottom wall and bounding side walls, and a filter bank positioned parallel to and spaced below said top wall. The filter bank comprises a supporting latticework which defines a plurality of rectangular open areas, a plurality of supporting tie rods connected between said top wall of the clean room and the latticework, and a plurality of high efficiency air filters positioned on the latticework, with one of the filters covering each of the open areas. A plurality of wall panels are suspended downwardly from the latticework, and attachment means are provided for releasably supporting each of the wall panels, with each attachment means being disposed coaxially with and operatively connected to one of the tie rods, and such that the weight of suspended wall panels is borne directly by the tie rods and not by the latticework. The wall panels are thus adapted to be positioned within the clean room in a selected configuration to define separated work areas.
Referring more particularly to the drawings, FIG. 1 illustrates a clean room 10 which embodies the features of the present invention. The clean room includes a top wall 11, a bottom wall or floor 12, and four bounding side walls 14. Also, a filter bank 16 is positioned parallel to and spaced below the top wall, and the filter bank comprises a supporting latticework 18 composed of interconnected lengthwise and crosswise members. More particularly, and as best seen in FIG. 5, the lengthwise and crosswise members are defined by a plurality of X-shaped connectors 20 which are supported from the top wall 11 of the clean room by means of tie rods 21, with each tie rod having a threaded lower end portion 22. Each X-shaped connector 20 includes a centrally disposed boss 23 (FIGS. 4 and 6) for threadedly engaging the lower end portion 22 of the associated tie rod, and the lower end portion of each tie rod extends completely through the boss for the reasons described below. Each connector also includes four extensions 25 which radiate outwardly from a central location and at right angles to each other. Also, each of the extensions 25 has a U-shaped cross-sectional configuration which opens upwardly toward the top wall. U-shaped channels 26 span and are carried between the aligned extensions 25 of the adjacent X-shaped connectors 20. A plurality of filters 28 are supported upon the latticework 18, with each filter 28 covering one of the rectangular open areas defined by the latticework. More particularly, each filter 28 comprises a depending peripheral skirt 29 which is adapted to rest upon the members of the latticework and so as to be embedded in a fluid or gum sealant 30 which is carried within the connectors and channels so as to form an air tight seal therebetween.
FIG. 1 illustrates an embodiment wherein the wall panels 40 are arranged to define a single isolated work area within the bounds of the clean room, and FIGS. 2-3 illustrate an embodiment wherein the wall panels define three separate work areas within the room. In each case, the wall panels of the present invention may be selectively moved within the clean room to define still different arrangements of the work areas.
FIGS. 5-9 illustrate a second embodiment of the invention, wherein the wall panels 60 each comprise a supporting framework of interconnected horizontal and vertical channel members, and a number of sheet members 62 realeasably connected to and overlying the frame members. More particularly, the frame members comprise a top channel member 63 adapted to be aligned immediately below a lengthwise or crosswise member of the latticework 18, a bottom channel 64 member positioned immediately above the floor of the clean room, a number of vertical channel members 65 extending between the top and bottom members, and a stabilizing horizontal member 66 joining the vertical members. The vertical members 65 include oval shaped openings 69 at spaced locations along one side, and a clamping member 67 is inserted into each of these openings in the manner best seen in FIGS. 8-9. The sheet members 62 are provided with tab-like extensions 68 at spaced apart locations along each side edge and which correspond to the distance between the opening 69 of the vertical channel members 65. 59ce067264
