IfcDamperTypeEnum

Definition from IAI: This enumeration defines the various types of damper:

- CONTROLDAMPER: Control damper used to automatically modulate the flow of air by adjusting the position of the blades.
- FIREDAMPER: Fire damper used to prevent the spread of fire for a specified duration.
- 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.
- BACKDRAFTDAMPER: Backdraft damper used to restrict the movement of air in one direction.
- 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.
- USERDEFINED: User-defined damper.
- NOTDEFINED: Undefined damper.
