Smoke Extract Duct

Smoke is recognized as the major killer during fire outbreaks. It can spread quickly to nearby buildings that are quite remote from the original flash, threatening life and damaging property. Stairwells and elevator shafts frequently become smoke logged, blocking evacuation routes and preventing firefighters and other rescue teams from doing their critical jobs. Air Master Smoke Extract ductwork is a key element of a fire strategy, by safely channelling smoke out of the building.

Fire-rated HVAC ducts with insulation ensures that the temperature measured, outside in Type A and inside in Type B, does not exceed 140°C mean average above ambient during the test, and is deemed automatica I lyfa i led ifanythermocouple rises to 180°C.
