[0046] Referring now to FIGS. 1B, 1C, and 2D; some of the embodiments of the combination seal 112 are illustrated. The filter is sealed to the base or filter support by the combination seal 112. The combination seal 112 uses intumescent material(s), organic, or inorganic compound(s) in conjunction with a seal material. The intumescent material is interspersed within the seal material in the form of flecks or particles. The flecks or particles can be of several types, some that activate at lower temperatures and some at higher temperatures. They can also be of different expatiation ratios. The flecks or particles can be of different sizes and densities within the seal material for the desired performance. By limiting the quantity of flecks or particles of the seal by volume, the seal effectiveness and longevity can be maintained without compromise. This creates a new type of seal that is more heat resistant than the existing seal material by itself. The intumescent material is a material that undergoes a chemical change when exposed to heat or flames, becoming viscous then forming expanding bubbles that harden into a dense, heat insulating multi-cellular char. This expanding char can seal, insulate, and protect mating surfaces and joints, helping to prevent warping, subsequent leakage and damage.

[0047] Referring now to FIG. 1B one of the embodiments of the combination seal 112 is illustrated. This embodiment 112 uses a seal material 116. The seal material 116 in this embodiment is made of gel material. The seal material 116 is interspersed with flecks or particles 118. The flecks or particles 118 are made of intumescent material. In the event of a fire or hot air the gel seal material 116 and the flecks or particles 118 expand to maintain an effective seal.

[0048] The gel seal material 116 and the flecks or particles 118 intumescent material undergo a chemical change when exposed to heat or flames, becoming viscous then forming expanding bubbles that harden into a dense, heat insulating multi-cellular char. This expanding char seals, insulates, and protects mating surfaces and joints, helping to prevent warping, subsequent leakage and damage.

[0049] Referring now to FIG. 1C another of the embodiments of the combination seal 112 is illustrated. This embodiment 112 uses a seal material 120. The seal material 120 in this embodiment is made of a gel material. The seal material 120 is interspersed with flecks or particles 122 and flecks or particles 124. The flecks or particles 122 and 124 are made of intumescent materials. In the event of a fire or hot air the gel seal material 120 and the flecks or particles 122 and 124 expand to maintain an effective seal.

[0050] The gel seal material 120 intumescent material and the flecks or particles 122 and 124 intumescent material undergo a chemical change when exposed to heat or flames, becoming viscous then forming expanding bubbles that harden into a dense, heat insulating multi-cellular char. This expanding char seals, insulates, and protects mating surfaces and joints, helping to prevent warping, subsequent leakage and damage. The flecks or particles 122 and 124 are different. In one embodiment, the flecks or particles 122 and the flecks or particles 124 are of different types. For example, the flecks or particles 122 are made of an intumescent material that activates at a lower temperature and the flecks or particles 124 are made of an intumescent material that activates at a higher temperature. They can also be of different expatiation ratios.

[0051] Referring now to FIG. 1D another of the embodiments of the combination seal 112 is illustrated. This embodiment 112 uses a seal material 126. The seal material 126 in this embodiment is made of gel material. The seal material 126 is interspersed with flecks or particles 128 and flecks or particles 130. The flecks or particles 128 and 130 are made of intumescent materials. In the event of a fire or hot air the seal material 126 and the flecks or particles 128 and 130 expand to maintain an effective seal.

[0052] The seal material 126 intumescent material and the flecks or particles 128 and 130 intumescent material undergo a chemical change when exposed to heat or flames, becoming viscous then forming expanding bubbles that harden into a dense, heat insulating multi-cellular char. This expanding char seals, insulates, and protects mating surfaces and joints, helping to prevent warping, subsequent leakage and damage. The seal material 126 and the flecks or particles 128 and 130 are made of intumescent material; however, the intumescent materials are different. The flecks or particles 128 and the flecks or particles 130 are of different types. For example, the flecks or particles 128 are and the flecks or particles 130 are of different sizes and densities. The flecks or particles 128 are larger and the flecks or particles 130 are smaller. The flecks or particles 128 are of a first density and the flecks or particles 130 are of a second and different density.

[0117] Component 402first ductwork,

[0118] Component 404second ductwork,

[0119] Component 406clamp,

[0120] Component 408first intumescent material seal unit,

[0121] Component 410second intumescent material seal unit, and

[0122] Component 412combination seal unit.

[0123] Referring again to FIG. 4, the combination seal unit 412 uses intumescent material(s), organic, or inorganic compound(s) in conjunction with a seal material. The intumescent material is interspersed within the seal material in the form of flecks or particles. The flecks or particles can be of several types, some that activate at lower temperatures and some at higher temperatures. They can also be of different expatiation ratios. The flecks or particles can be of different sizes and densities within the seal material for the desired performance. By limiting the quantity of flecks or particles of the seal by volume, the seal effectiveness and longevity can be maintained without compromise. This creates a new type of seal that is more heat resistant than the existing seal material by itself. The intumescent material is a material that undergoes a chemical change when exposed to heat or flames, becoming viscous then forming expanding bubbles that harden into a dense, heat insulating multi-cellular char. This expanding char can seal, insulate, and protect mating surfaces and joints, helping to prevent warping, subsequent leakage and damage.

[0124] Although the description above contains many details and specifics, these should not be construed as limiting the scope of the application but as merely providing illustrations of some of the presently preferred embodiments of the apparatus, systems, and methods. Other implementations, enhancements and variations can be made based on what is described and illustrated in this patent document. The features of the embodiments described herein may be combined in all possible combinations of methods, apparatus, modules, systems, and computer program products. Certain features that are described in this patent document in the context of separate embodiments can also be implemented in combination in a single embodiment. Conversely, various features that are described in the context of a single embodiment can also be implemented in multiple embodiments separately or in any suitable subcombination. Moreover, although features may be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination may be directed to a subcombination or variation of a subcombination. Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. Moreover, the separation of various system components in the embodiments described above should not be understood as requiring such separation in all embodiments.

[0125] Therefore, it will be appreciated that the scope of the present application fully encompasses other embodiments which may become obvious to those skilled in the art. In the claims, reference to an element in the singular is not intended to mean one and only one unless explicitly so stated, but rather one or more. All structural and functional equivalents to the elements of the above-described preferred embodiment that are known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the present claims. Moreover, it is not necessary for a device to address each and every problem sought to be solved by the present apparatus, systems, and methods, for it to be encompassed by the present claims. Furthermore, no element or component in the present disclosure is intended to be dedicated to the public regardless of whether the element or component is explicitly recited in the claims. No claim element herein is to be construed under the provisions of 35 U.S.C. 112, sixth paragraph, unless the element is expressly recited using the phrase means for.

[0126] While the apparatus, systems, and methods may be susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and have been described in detail herein. However, it should be understood that the application is not intended to be limited to the particular forms disclosed. Rather, the application is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the application as defined by the following appended claims.
