Complete your air conditioning and ventilation installations with professional-grade duct and duct fittings from iSupply Electrical.
Our comprehensive range includes AVOL air conditioning ducting systems and Fantech components designed for licensed electricians and contractors working on residential, commercial, and industrial projects across Australia.
Professional Ducting Solutions for Every Project
Whether you’re installing split system air conditioning in residential properties or managing large-scale commercial ventilation systems, our duct and duct fittings inventory delivers the components you need to complete installations efficiently.
From 100mm AVOL air conditioning duct systems with ceiling caps, end covers, and mounting blocks to Fantech reducers, grilles, and flexible ducting options, we stock over 15,000 electrical products to keep your projects moving forward.
Our range includes essential fittings like vertical elbows, flat elbows, tee joints, cover joints, and wall corners that enable you to navigate tight spaces and complex installation requirements without compromising airflow efficiency.
Fantech duct reducers in multiple size configurations (100mm to 300mm) allow seamless transitions between different duct diameters, while external grilles with gravity louvres and fixed louvres provide professional finishing touches for both internal and external installations.
Maximize Installation Efficiency
Proper duct sizing and fitting selection directly impacts HVAC system performance and energy efficiency. Undersized ducts restrict airflow and force systems to work harder, while quality fittings like our Fantech joiners, wall tubes, and ceiling grilles ensure airtight connections that prevent conditioned air loss.
Browse our complete Air Movement range for complementary products including inline fans, exhaust systems, and ventilation accessories that integrate seamlessly with your ductwork installations.
For electricians managing multiple concurrent projects, we offer competitive wholesale pricing on bulk purchases, same-day pickup from our Fairfield East location, and fast Australia-wide delivery within 1-6 business days.
Stock your van with essential duct components and avoid costly project delays caused by product unavailability.
FAQs
What duct sizes are available for air conditioning installations?
We stock AVOL air conditioning duct systems in 100mm diameter and Fantech components ranging from 100mm to 370mm, including duct reducers for transitioning between different sizes (125mm-100mm, 150mm-125mm, 200mm-150mm, and up to 310mm-300mm configurations). Proper duct sizing ensures optimal airflow and system efficiency for your specific HVAC installation requirements.
Do you stock both flexible and rigid duct options?
Yes, our range includes Fantech flexible non-insulated ducting (such as DUCT125-6M-TP) for navigating tight roof spaces and ceiling cavities, as well as rigid components like AVOL air conditioning duct sections, elbows, and fittings for permanent installations. Flexible ducts should be kept as short as possible and properly installed to maintain airflow efficiency.
What fittings do I need to complete an air conditioning duct run?
Essential fittings include duct joiners for connecting sections, reducers for size transitions, elbows (vertical and flat) for directional changes, tee joints for branching, ceiling caps or grilles for room outlets, and external grilles with louvres for wall penetrations. Our AVOL and Fantech ranges provide complete fitting solutions from the main unit to final outlets.
Are your duct fittings suitable for commercial projects?
Absolutely. Our Fantech duct components are designed for both residential and commercial applications, including large-diameter options (up to 370mm), heavy-duty external grilles for HXM and RP series fans, and professional-grade reducers and mounting systems that meet Australian standards for commercial ventilation installations.
How do I prevent air leaks in ductwork installations?
Use quality duct tape (like our Fantech 30-meter rolls), ensure proper fitting connections with compatible joiners and reducers, and seal all joints thoroughly during installation. Properly sealed ductwork maximizes efficiency, reduces energy waste, and maintains consistent air pressure throughout the system. Quality fittings from our range ensure airtight connections that prevent conditioned air from escaping into unconditioned spaces.
Can I order duct fittings for delivery across Australia?
Yes, we offer Australia-wide delivery with dispatch within 1-6 business days, plus same-day pickup available from our Fairfield East warehouse for Sydney-based electricians and contractors. Order online 24/7 and access trade pricing on all duct and duct fittings for your residential, commercial, and industrial projects.
