CFDM fire dampers are diaphragms in ducted ventilation systems that prevent the spread of fire and products of combustion from one fire segment to another by closing the air duct at points of fire separation structures. The damper diaphragm automatically closes the air duct with a closing spring.
BRF Magneto
BRF Magneto magnetic backdraught shutter has been designed to be mounted inside 125mm diameter round ventilation ducts to prevent the return of ventilated air. The product stops the ingress of external air at extractor hoods.
BRF Magneto is designed for installation in a horizontal part of a ventilation duct. The product should be inserted in the duct so that the arrow with the “TOP” sign points upwards. It is necessary to leave appropriate space behind the BRF Magneto to ensure proper operation of the magnetic flap.
