Air Master Fire Rated Ductwork helps maintain pressurization systems and ensures compartmentation. The integrity of the duct and its ability to function must be maintained in the event of a fire. The HVAC Ductwork is a non-coated system, suitable for installation in multi-compartment, single compartment, stud wall, solid wall, and aerated concrete floors. A comprehensive set of support system is provided. Penetration seals guidance is provided with detailed drawings.
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 Duct with Insulation is a factor preventing flashover
Exhausting smoke from a fire affected area creates a potential flash over risk in compartments other than the fire compartment. As per international standards, insulation certainly help to prevent flashover.
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.
Kitchen Extraction Duct
Kitchen extract ductwork stances a specific risk due to the presence of combustible contaminants, namely grease, inside the ductwork. When a kitchen extract passesth rough multi-compartments, there is a risk from a fire in a compartment outside the kitchen. This can cause the grease inside the duct to ignite, and the fire to spread throughout the building.
