SMOKEDAMPER: Smoke damper used to prevent the spread of smoke.
FIRESMOKEDAMPER: Combination fire and smoke damper used to preven the spread of fire and smoke.

RELIEFDAMPER: Relief damper used to allow air to move upon a buildup of a specified pressure differential.
BLASTDAMPER: Blast damper.
GRAVITYDAMPER: Gravity damper closes from the force of gravity.
GRAVITYRELIEFDAMPER: Gravity-relief damper used to allow air to move upon a buildup of enough pressure to overcome the gravitational force exerted upon the damper blades.
FUMEHOODEXHAUST: Fume hood exhaust damper.
BALANCINGDAMPER: Damper used for purposes of manually balancing pressure differences.
