FIDI
FIDi is a self-acting back draught damper designed to prevent the spread of combustion gas via the intake air system in ventilation systems. FIDi is equipped with measurement and commissioning functions, thus it can also be used as a adjustment damper.
The commissioning unit is integrated in the insert, which mean the setting does not change when the insert is dismantled.There is a metering socket, knob and K-factors on the outside.
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 supply 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.
