This enumeration defines the various types of damper

7.5.2.12.2 Type values

Type Description
BACKDRAFTDAMPER

Damper used for purposes of manually balancing pressure differences. Commonly operated by mechanical adjustment.

BALANCINGDAMPER

Backdraft damper used to restrict the movement of air in one direction. Commonly operated by mechanical spring.

BLASTDAMPER

Blast damper used to prevent protect occupants and equipment against overpressures resultant of an explosion. Commonly operated by mechanical spring.

CONTROLDAMPER

Control damper used to modulate the flow of air by adjusting the position of the blades. Commonly operated by an actuator of a building automation system.

FIREDAMPER

Fire damper used to prevent the spread of fire for a specified duration. Commonly operated by fusable link that melts above a certain temperature.

FIRESMOKEDAMPER

Combination fire and smoke damper used to prevent the spread of fire and smoke. Commonly operated by a fusable link and a smoke detector.

FUMEHOODEXHAUST

Fume hood exhaust damper. Commonly operated by actuator.

GRAVITYDAMPER

Gravity damper closes from the force of gravity. Commonly operated by gravitational weight.

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. Commonly operated by gravitational weight.

RELIEFDAMPER

Relief damper used to allow air to move upon a buildup of a specified pressure differential. Commonly operated by mechanical spring.

SMOKEDAMPER

Smoke damper used to prevent the spread of smoke. Commonly operated by a smoke detector of a building automation system.

USERDEFINED

User-defined damper.

NOTDEFINED

Undefined damper.
