FIDM
FIDm is a self-acting back draught damper designed to prevent the spread of combustion gases via the intake air system in ventilation systems. FIDm is equipped with an actuator and is suitable for systems where you adjust the ventilation as required.
The back draught damper can be controlled with the on/off function or continuously regulated 0-10 V. The end position can be limited for max/min positions. FIDm is also equipped with a metering socket for commissioning.
The back draught damper should be used in combination with a fan in use solution, smoke venting via exhaust air or the like and to maintain its function requires the intake air fan to be operational during the fire. The fire protection functions work for all design fire scenarios that can be expected to occur with traditionally used fire development rates. Planning and fire protection analysis are to be made by fire experts
