Panel seal for an air handling unit
First Claim
1. In an air handling unit containing modular sections, each section having a framework with perpendicularly aligned rectangular shaped panel openings therein that are closed by close fitting panels that are latched into said panel openings, apparatus for sealing said panels in said panel openings that includestubular structural elements mounted to form each panel opening so that each panel opening shares a common structural element with an adjacent perpendicularly aligned panel opening, said common structural elements each containing a rail extending along said element, a seal assembly mounted upon said rail that includes a rigid elongated plate having bulb seals mounted along opposing edges of said plate so that the bulb seal extending along one edge of the plate is capable of sealing against a first panel contained in one of the adjacent panel openings and the seal extending along the other edge is capable of sealing against a second panel contained in the adjacent perpendicularly aligned panel opening.

Abstract
An air handling system containing sections each having a framework made up of tubular structural elements defining each perpendicularly aligned openings each of which shares a common structural element with its neighbors. The openings are closed by panels that are latched into the openings. Said assemblies are installed around the perimeter of each rectangular opening. Each assembly includes a rigid plate having two bulb seals extending along opposite edges of the plate that are coextruded with the plate. The plate is mounted at about a 45° angle along an inside corner edge of each commonly shared structural element so that a seal on one side of the plate services one opening while the other seal services the adjacent opening. The ends of the seals are mitered and the plate is inserted into a slot formed in molded corner retainers that support the structural elements in assembly. The mitered corners of the four seals surrounding an opening are placed in abutting contact to create a positive seal about each opening in the modular section.
