Abstract
Abstract A modular support system for supporting a plurality of high efficiency particulate air filters (HEPA). The modular support system includes a grid of filter support members joined at their intersection by connectors. The support members include first and second side walls and a bottom wall forming a substantially U-shaped channel for receiving a sealant. The first and second side walls extend substantially perpendicular to the bottom wall. The first and second side walls each include a substantially triangular shaped lip extending along their upper edge for releasably securing the support member to an adjacent connector. The connectors include at least two arms extending radially from a center portion. The arms include first and second side walls and a bottom wall forming a substantially U-shaped channel. The dimensions of the U-shaped channel of the arms are such that the arms fit snugly in the U-shaped channels of the corresponding support members. The U-shaped channels of the connectors can be inserted vertically or horizontally into the U-shaped channels of the support members. The triangular lips of the first and second walls of the support member provide a snap fit for releasably securing the two components together without the use of conventional rigid type fastening devices such as bolts, welds, cement, etc.
