ECO DUCT

Eco Duct low profile rectangular duct and fittings are the trade solution for ducted air conditioning installations where standard round flexible duct won't fit. The 300 x 70mm rectangular profile is engineered to run through restricted ceiling cavities, wall spaces, inter-floor voids and subfloor areas where conventional duct simply cannot go — making it the go-to product for retrofit, renovation and new build installations with limited cavity depth.
The full Eco Duct fitting range covers everything needed to complete a low profile duct system from start to finish — straight duct lengths, horizontal and vertical bends, T-pieces, joiners, round to rectangular adaptors, rangehood connections and support clips. All fittings are colour coded green for fast, error-free size identification on site and manufactured to AS/NZS 1530.3-1999 for fire performance compliance.
Where Eco Duct is used:
- Retrofit and add-on ducted installations where existing ceiling cavities are too shallow for round duct
- Skillion roof and low-pitch roof homes with restricted ceiling void depth
- Concrete slab and double-storey constructions where inter-floor space is limited
- Wall cavity duct runs where round duct cannot be routed
- Kitchen rangehood exhaust runs through tight wall and ceiling spaces
- Any installation requiring a clean, low-profile solution in place of bulky round flexible duct
Trade note: Eco Duct has a higher resistance per metre than equivalent round flexible duct due to its rectangular cross-section. Always calculate total system static pressure — including straight runs, bends and transition fittings — before finalising duct layouts to ensure the system operates within the unit manufacturer's rated static pressure tolerance.
