A foldably tensioned boot loadable air damper device for controlling the flow of air through ductwork, and a method of installing same. The damper device includes an actuator having a retractable member and a pivoting member, wherein the pivoting member is operatively connected to the retractable member of the actuator. The damper device also includes at least one support base supporting the actuator and the pivoting member with respect to each other, a foldable damper blade attached to the pivoting member, and at least one tensioned hinge member operatively connected to the foldable damper blade for unfolding the damper blade. The damper device may be inserted through a register boot and into a ductwork when folded.

1. A boot loadable air damper device for controlling the flow of air through ductwork, the damper device comprising: an actuator having a retractable member;a pivoting member, wherein said pivoting member is operatively connected to said retractable member of said actuator;at least one support base
1. A boot loadable air damper device for controlling the flow of air through ductwork, the damper device comprising: an actuator having a retractable member;a pivoting member, wherein said pivoting member is operatively connected to said retractable member of said actuator;at least one support base supporting said actuator and said pivoting member with respect to each other;a foldable damper blade attached to said pivoting member, wherein said foldable damper blade has at least three spaced apart portions foldably attached to one another, including a first portion, a middle portion and a second portion, where said foldable damper blade is configured to fold along each of two substantially parallel linear paths through the damper blade, a first of the two paths disposed between the first portion and the middle portion and a second of the two paths disposed between the middle portion and the second portion; andat least one tensioned hinge member operatively connected to said foldable damper blade and configured to cause said foldable damper blade to be under tension when said damper blade is held in a folded state, and to cause said damper blade to unfold in response to the tension when said damper blade is released from the folded state,wherein said air damper device is configured to be installed through a register boot into an unmodified ductwork. 2. The boot loadable air damper device as defined in claim 1, wherein said actuator is an air pressure actuator. 3. The boot loadable air damper device as defined in claim 1, wherein said actuator is an electro-mechanical actuator. 4. The method of claim 3, wherein said electro-mechanical actuator further comprises a portable power supply. 5. The boot loadable air damper device as defined in claim 1, wherein said pivoting member further comprises at least two pins. 6. The boot loadable air damper device as defined in claim 5, wherein said at least two pins are nylon pins. 7. The boot loadable air damper device as defined in claim 1, wherein said foldable damper blade further comprises a sealing member. 8. The boot loadable air damper device as defined in claim 7, wherein said sealing member is made of a flexible material. 9. The boot loadable air damper device as defined in claim 1, wherein said at least one tensioned hinge member includes a spring. 10. The boot loadable air damper device as defined in claim 1, wherein said damper device further comprises a foldable sheet member, wherein said foldable sheet member is attached to said at least one support base. 11. The boot loadable air damper device as defined in claim 10, wherein said foldable sheet member is a magnetic foldable sheet member. 12. The boot loadable air damper device as defined in claim 1, wherein said damper device further comprises a stop member. 13. A boot loadable air damper device for controlling the flow of air through ductwork, the damper device comprising: a foldable damper blade having at least three spaced apart portions foldably attached to one another, including a first portion, a middle portion and a second portion, where said foldable damper blade is configured to fold along each of two substantially parallel linear paths through the damper blade, a first of the two paths disposed between the first portion and the middle portion and a second of the two paths disposed between the middle portion and the second portion;means for pivotally actuating said foldable damper blade; andmeans for unfolding said damper blade, wherein said damper blade is under tension by said means for unfolding when said damper blade is held in a folded state, and said damper blade unfolds in response to the tension when said damper blade is released from the folded state, and wherein said air damper device is configured to be installed through a register boot into an unmodified ductwork. 14. The boot loadable air damper device as defined in claim 13, wherein said means for pivotally actuating is pneumatic. 15. The boot loadable air damper device as defined in claim 13, wherein said means for pivotally actuating is electro-mechanical. 16. The boot loadable air damper device as defined in claim 15, wherein said electro-mechanical means for pivotally actuating includes a portable power supply. 17. The boot loadable air damper device as defined in claim 13, wherein said foldable damper blade further comprises a sealing member. 18. The boot loadable air damper device as defined in claim 17, wherein said sealing member is made of a flexible material. 19. The boot loadable air damper device as defined in claim 13, wherein said means for unfolding said damper blade includes at least one tensioned hinge member. 20. The boot loadable air damper device as defined in claim 19, wherein said at least one tensioned hinge member further comprises a spring. 21. The boot loadable air damper device as defined in claim 13, wherein said damper device further comprises a foldable means for securing said damper device to an interior of said ductwork. 22. The boot loadable air damper device as defined in claim 21, wherein said foldable means for securing is magnetic. 23. The boot loadable air damper device as defined in claim 13, wherein said damper device further comprises a means for stopping an unfolding of said foldable damper blade. 24. The boot loadable air damper device as defined in claim 13 further comprising means for supporting said foldable damper blade and said means for pivotally actuating with respect to each other.
