Special Note
Construction of buildings in bushfire prone areas
AS3959:2009, clause 6.6.5(b) "Roof penetrations" states:
Openings in vented roof lights, roof ventilators or vent pipes shall be fitted with ember guards made from a mesh or perforated sheet with a maximum aperture of 2mm, made of corrosion-resistant steel, bronze or aluminium.
Backdraft dampers
Backdraft shutters are an optional extra. The pressure loss across the shutter has to be added to the system pressure before making fan selections.
Kitchen Hood Exhaust Systems
AS/NZS1668.1:1998, Clause 11.2.5 states that, for commercial installations:- "kitchen exhaust fan casings and cowls shall be manufactured from non-combustible materials that have a fusing temperature above 1000°C".
Suggested Specification
The roof ventilators shall be of the GL Gamma Series with bushfire code compliance as designed and manufactured by Fantech Pty Ltd.
Impellers shall be of backward-curved centrifugal design and driven by speed-controllable external rotor motors with integral thermal protection.
They shall be constructed from galvanised steel and be of vertical exhaust design.
Ember protection mesh shall be bronze or steel with openings a maximum of 2mm. The windband shall incorporate
quick-release toggle clamps to provide easy access for cleaning and maintenance.
All data shall be based on tests on a complete assembled unit to ISO5801:1997 for air flow and BS848:Part 2, 1985 for noise.
