TROX Combination Smoke & Fire Damper Type ‘MSD & SFD’

Trox smoke, fire, fire and smoke dampers provide an automatic means of localizing areas of smoke and or fire in ventilation systems.
To prevent the distribution of fire and/or smoke through ventilation ductwork Trox dampers offer an effective barrier maintaining integrity in a fire situation up to 3 hours (SFD) and this is combined with low leakage characteristics for smoke management (MSD and SFD).
Trox dampers are suitable for installation in sheet metal ductwork, or in walls and ceiling slabs made from concrete or brickwork, and in lightweight partition walls.
