Description

GRAFT® FR Damper is used to fire proof ventilation ducts where they penetrate fire rated constructions such as fire compartments and fire walls, preventing the passage of fire and smoke both surrounding and inside the ventilation duct.

Key Features

  • Maintenance-free and no electrical connections necessary.
  • The same damper can be installed in both walls and floors.
  • It seals against penetration of fire and smoke both surrounding and inside the ventilation duct.
  • Closes in the area where the fire is located but not elsewhere so the ventilation system can be used to extract smoke from areas that are not on fire.
  • Keeps the temperature in the duct network lower than 120°C and will therefore protect fans and sensitive units in the system.
  • Insulation of ducts is not necessary.
  • Service life of more than 50 years; the damper will last the same life cycle as the ventilation system.
  • The dampers are designed to fit standard ducting equipment so that the ducting system installer can easily fit the dampers.
  • The dampers are attached to the inside of the ducts, giving the benefit of space-saving.
  • An aperture can include several dampers and in addition technical services such as cables, cable trays and pipes.
  • The dampers are only 15 cm long and bends can be connected right behind the fire seal (can also be special ordered in other sizes).
  • The damper can be attached to a vent on one side.
