Ezifit Thru Roof Exhaust Fan - Bushfire Code Compliant (BAL-40) – ECE154-BFC
Performance Curve - ECE154-BFC
Description
The Ezifit Roof Series, with BAL-40 bushfire code compliance, has been developed and tested for exhaust air applications in bushfire prone regions. They are driven by a high performance centrifugal fan and have a low profile design. They can exhaust from a number of points within the building and are available
in 150 and 200mm fan sizes.
Features Robust, galvanised steel construction.
Speed-controllable with electronic controller.
High performance, low noise backward-curved centrifugal impellers.
High quality bronze mesh provides ember protection.
Comes with convenient 3-pin plug and lead.
Designed for downflow discharge.
Can be mounted at angles up to 30°.
Powder coated finish is an optional extra.
Compliant to AS3959:2009 up to and including BAL-40.

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.
Suggested Specification
The roof ventilators shall be of the Ezifit Roof Series with bushfire code compliance as designed and manufactured by Fantech Pty Ltd.
The backward-curved centrifugal fans shall be direct-driven by continuous rated, speed-controllable external rotor motors with thermal protection.
They shall be constructed from galvanised steel, be of downflow discharge design and include a 3-pin plug and lead.
Ember protection mesh shall be bronze or steel with openings a maximum of 2mm.
All data shall be based on tests on a complete assembled unit according to ISO5801:2007 for air flow and BS848:Part 2, 1985 for noise.Technical Data - ECE154-BFC
