S-MFD Fire and Gas-Fire Damper SOLAS A0-A60

The MED certified S-MFD fire damper, equipped with a thermal fuse, is designed to prevent the spread of flames within the ventilation and air conditioning system for Marine and Oil&Gas installations. The heavy frame, made of 4 welded pieces, allows installation in load-bearing structures such as decks and bulkheads. The S-MFD fire damper, due to its construction and strength, is particularly suitable for installation on leisure ships, cruise ships, commercial vessels, HVAC systems, offshore and onshore oil and gas installations and for engine room ventilation.
S-MFD series can perfectly replace the phased out SFD/SFDT models.
