achieve compliance for the many different and separate elements where our dampers can be utilised. These incredible efforts led to our larg- est catalogue of compliant installations to date,” Trant said.
There is also the need to update older build- ings that currently could have non-compliant fire dampers installed or fire dampers which are coming to their end-of-life.
To address this Kilargo provides an extensive list of retro-fit installations to meet the needs of this important and growing market.
To achieve compliance and adherence to AS1682.2-2015, Kilargo Low Loss fire dampers also come with an innovative peel off install- ers’ sticker.
Providing useful advancements while main- taining lightweight, easy to install and easy to maintain intumescent fire dampers, is what makes Kilargo the industry leader of intumes- cent fire dampers.
Bullock Manufacturing managing director, Jamie Scott, said the company is proud to be the national distributors of Kilargo Intumescent Fire Dampers.
“We have worked with Kilargo from the be- ginning, and it is great to see this progress and innovation in the fire protection industry,” Scott said.

THE INTRODUCTION OF Intumescent Fire Dampers to the Australian HVAC market over 20 years ago has seen this valuable and impor- tant technology develop and gain widespread recognition for its vital suppression and con- tainment of fires.
Initially the industry found the thickness of the intumescent slats often proved a hindrance to its widespread adoption with concerns over pressure loss from the restricted free area of the damper.
“A PRESSURE DROP CALCULATOR DERIVED FROM AIRFLOW TESTING WITH VIPAC ALSO PROVIDES ASSISTANCE.”
Kilargo’s national sales manager, Liam Trant, recalls the discussions surrounding the use of IFDs (Intumescent Fire Dampers).
“IFDs are lightweight, easy to install and even easier to maintain, but the achilles heel was the concern around pressure drop,” he said.
The introduction of NCC2022 and the conclu- sion of the grandfather clause noted in NCC2019 referencing the requirement of all fire dampers to be tested - to AS1530.4-2014 Section 10 (non- ducted air transfer systems) and 11 (ducted sys-
tems) - meant a requirement for all fire dampers to be retested to the latest and much more strin- gent standards.
“We had a big job ahead of us and though daunting at first, Kilargo saw this as an incredi- ble opportunity to do better and make advanced improvements to our intumescent fire damper design,” Trant said.
“To achieve this, we took on feedback from all our valued stakeholders, including installers, builders, designers, manufacturing, standards committee and pretty much anyone in the in- dustry who had something to say.”
These collaborative efforts resulted in the pro- duction of the industry leading Kilargo IFD-LL and IFD44-LL fire dampers.
LL stands for Low Loss, according to Kilargo’s sales and applications engineer, Cem Okan.
“We wanted to address the pressure drop is- sue first and foremost so now the slats are pro- duced 50 per cent thinner which gives a damper free area of around 75 per cent,” Okan said.
New advancements mean Kilargo now pro- vides a pressure drop calculator derived from airflow testing with Vipac for vital design as- sistance.
To reduce the headache of meeting insula- tion requirements for fire dampers in AS1668.1- 2015, Kilargo also offers refined methods to achieve insulation without the need for two me- tres of rigid duct.
