an air source configured to supply air into the seal apparatus; a plurality of valves including at least a first valve and a second valve, wherein the first valve is coupled to the air source, the first valve configured to inject air into the seal apparatus at a rate slow enough to allow the door assembly to fully close before the seal apparatus expands to push against the door assembly, wherein the second valve is coupled to the seal apparatus, the second valve configured to release air from the seal apparatus at a rate quick enough to allow the door assembly to be opened without damaging the seal apparatus. ## Claims ### Claim 1 A door sealant system, comprising: a seal apparatus configured about a door assembly; an air source configured to supply air into the seal apparatus; a plurality of valves including at least a first valve and a second valve, wherein the first valve is coupled to the air source, the first valve configured to inject air into the seal apparatus at a rate slow enough to allow the door assembly to fully close before the seal apparatus expands to push against the door assembly, wherein the second valve is coupled to the seal apparatus, the second valve configured to release air from the seal apparatus at a rate quick enough to allow the door assembly to be opened without damaging the seal apparatus. ### Claim 2 (depends on 1) The door sealant system of claim 1, wherein the door assembly is a roll-up door assembly having a plurality of panels. ### Claim 3 (depends on 2) The door sealant system of claim 2, wherein the seal apparatus includes an elastic membrane configured as an elongated tube disposed around a perimeter of the door assembly to apply an outward force against the plurality of panels when the elongated tube is expanded. ### Claim 4 (depends on 1) The door sealant system of claim 1, wherein the first valve is an air regulator/activation valve. ### Claim 5 (depends on 1) The door sealant system of claim 1, wherein the second valve is a quick release valve. ### Claim 6 (depends on 1) The door sealant system of claim 1, wherein the seal apparatus includes two ends, each end disposed at each side of the door assembly. ### Claim 7 (depends on 6) The door sealant system of claim 6, wherein the second valve couples to the two ends of the seal apparatus to allow the air to be released through the two ends. ### Claim 8 A method for controlling an air flow rate for a seal apparatus disposed about a door assembly, the method comprising: first regulating a first rate of a pressurized air being injected into the seal apparatus, wherein the first rate is regulated to be slow enough to allow the door assembly to fully close before the seal apparatus expands to push against the door assembly; and second regulating a second rate of a pressurized air being released from the seal apparatus, wherein the second rate is regulated to be quick enough to allow the door assembly to be opened without damaging the seal apparatus. ### Claim 9 (depends on 8) The method of claim 8, wherein the first regulating is performed with an air regulator/activation valve. ### Claim 10 (depends on 9) The method of claim 9, wherein the air regulator/activation valve is automatically and electrically controlled. ### Claim 11 (depends on 10) The method of claim 10, wherein the air regulator/activation valve is automatically and electrically controlled using an electric solenoid valve. ### Claim 12 (depends on 10) The method of claim 10, wherein the air regulator/activation valve is automatically and electrically controlled via wireless communication. ### Claim 13 (depends on 8) The method of claim 8, wherein the second regulating is performed with a quick release valve. ### Claim 14 (depends on 13) The method of claim 13, wherein the second regulating comprises: coupling two ends of the seal apparatus to the quick release valve; and releasing the pressurized air from the seal apparatus through the two ends of the seal apparatus. ### Claim 15 (depends on 8) The method of claim 8, wherein the first regulating comprises injecting the pressurized air into the seal apparatus to expand an elastic membrane of the seal apparatus and to apply an outward force against panels of the door assembly. ### Claim 16 An apparatus for controlling an air flow rate for a seal apparatus disposed about a door assembly, the apparatus comprising: a first regulating means for regulating a first rate of a pressurized air being injected into the seal apparatus, wherein the first rate is regulated to be slow enough to allow the door assembly to fully close before the seal apparatus expands to push against the door assembly; and a second regulating means for regulating a second rate of a pressurized air being released from the seal apparatus, wherein the second rate is regulated to be quick enough to allow the door assembly to be opened without damaging the seal apparatus. ### Claim 17 (depends on 16) The apparatus of claim 16, wherein the first regulating means performs the regulation of the pressurized air with an air regulator/activation valve. ### Claim 18 (depends on 16) The apparatus of claim 16, wherein the second regulating means performs the regulation of the pressurized air with a quick release valve. ### Claim 19 (depends on 16) The apparatus of claim 16, wherein the second regulating means couples two ends of the seal apparatus to release the pressurized air from the seal apparatus through the two ends of the seal apparatus. ### Claim 20 (depends on 16) The apparatus of claim 16, further comprising means for injecting the pressurized air into the seal apparatus to expand an elastic membrane of the seal apparatus and to apply an outward force against panels of the door assembly.
