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
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:
Protection using Fire Resisting Enclosures
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.

Features of Fire Rated Ductwork
Successful testing and assessments are done for the duct size range up to 6000 millimeters in compliance with BS 476 part 24 and ISO 6944-1985 at internationally accredited Applus+ Laboratories at Barcelona, Spain.
Tested in horizontal as well as vertical orientation separately under cellulosic (standard time Vs. temperature curve) fire conditions and successfully achieved over 120 minutes of fire resistance for integrity and stability of
- Duct A (Fire Outside the ductwork)
- Duct B (Fire Inside the ductwork).

FIRE RATED DUCTWORK TYPES:
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.
