Airmaster Fire Rated Ductwork

Air Master was established in the year 1987 in the United Arab Emirates. Since then it has been known to be the pioneers in the field of manufacturing of air-distribution and air-control products like HVAC Air ducts, Splitter damper, Grilles, Diffusers, Louvers and Dampers. Having a successful startup of “Sheet Metal Ducting” in 2017, Air Master has now come up with a new product in line with the existing fire safety products – Fire Rated Ductwork.

“AIR MASTER” fire rated ductwork (AMFRD) is a non-coated type galvanized steel sheet met-al ductwork, tested in accordance with BS 476 part 24 and International standards in inter-nationally accredited laboratories. It is manufactured by specialized technical team using computerized state-of-the-art sheet metal duct manufacturing machines.

Air Master Fire Rated Ductwork is designed in a such a way that it is easy to install, light in weight and cost effective for the contractors, fulfilling stringent criteria of international codes of fire safety in buildings.

Fundamental Characteristics of Fire Rated Ductwork

Fire rated ductwork usually needs to pass through compartment walls or floors that will have a prescribed fire resistance period in terms of the load bearing capacity, integrity and insulation criteria, for durations of 30 to 240 minutes. It is a requirement that where these compartment walls/floors are penetrated by HVAC ducts or other building services, the fire performance criteria for the penetrated wall or floor are maintained, such that fire in one compartment may not spread to other areas. So, the fire resisting duct needs to maintain i.e., not compromise the fire resistance of the wall or floor through which it penetrates. The performance of a fire resisting duct which penetrates a fire resisting/separating element requires careful consideration by specifiers and controlling authorities. The standard periods of stability and integrity should in all cases be at least equal to those required for the penetrated element of construction.

The methods followed for the fire resistance of walls and floors penetrated by ventilation ducts in building regulatory requirements and under the guidance of BS 9999:

Method 1

Protection using Fire Dampers

Method 2

Protection using Fire Resisting Enclosures

Method 3

Protection using Fire Resisting Ductwork

It is most important to choose the most suitable fire resisting ductwork system for its intended application area to ensure that the ductwork fire performance meets the requirements of the relevant application.

Fire Ducts for Ventilation

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 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 systems 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 channeling smoke out of the building.
