Cylomade Duct Reducers are used to transition between different duct diameters within a spiral system, helping to maintain airflow balance as the ductwork branches or narrows. Each unit is tapered for a smooth, gradual change in diameter, reducing turbulence and minimising pressure loss. Manufactured from galvanised steel for durability and corrosion resistance, reducers are available in a wide range of size combinations to suit common duct configurations. Designed for compatibility with standard spiral duct, they install quickly and securely with minimal labour.

Cyclomade® T-pieces are used to create a 90-degree branch in spiral duct systems, allowing airflow to split or redirect. Manufactured in-house from galvanised steel, each unit is made to order for a precise fit and consistent airflow. While we list a small range of standard configurations online, most T-pieces are custom-built to suit individual system layouts. Our in-house engineers quote quickly and turn orders around efficiently. If you’ve got rough dimensions or a basic sketch, we can get started.
Y-pieces offer a more gradual airflow split than T-pieces, making them ideal for systems where pressure drop needs to be minimised. Fabricated from galvanised steel and made to order, each Y-piece is tailored for clean integration into spiral ductwork. A selection of common sizes is listed online, but most configurations are built to spec. Our in-house engineers respond promptly and work efficiently with whatever details you can provide — even a quick drawing on paper is enough to get going.
Branch Take-Offs are used to create a smooth branch line from a larger duct run, typically at an angle to improve airflow performance. Made from galvanised steel and manufactured in-house, BTOs can be configured to suit a wide range of duct diameters and layout requirements. We’ve included several frequently ordered sizes online, but most are made to order. Our in-house engineering team provides quick quoting and efficient turnaround. Just send through your measurements or a hand-drawn sketch and we’ll take care of the rest.
