Comparative Table

The IFD Aero allows for virtually unobstructed and guaranteed, trouble-free ventilation every day, while providing total closure in a fire event.

So what’s the difference between the IFD Aero and existing type 44 designs?

For 20 years, Kilargo’s IFDs have provided reliable, high-performance fire protection.  By re-focussing on everyday HVAC system critical requirements, we’ve been working behind the scenes to create a breakthrough design that takes everyday benefits and guaranteed fire compliance  to new levels.

With less noise, greater levels of system efficiency and based on years of HVAC industry consultation, it’s a smart step forward for quality constructions.

  Existing IFD IFD Aero
Turbulence Turbulent airflow

For type 44 intumescent fire dampers – less aerodynamic profile can result in pressure loss & acoustic concerns.

Reduced turbulence
New stealth blade profile promotes laminar airflow, resulting in lower pressure loss.
Profile Old slat profile
Heavy profile PVC cased intumescent or foiled slat, metal edged intumescent
New blade profile
Cutting edge slimline aerodynamic blade profile standard across all types.LESS BLADES = MORE AIR!
Compliance Complies with older standards
Australian Standard:AS1530.4:1990
Complies with latest standards
Fully tested to comply with Australian standard AS1530.4:2014
