Different from the Ducting up
As it’s name suggests, Small duct system (SDS) has very narrow air conditiong ducts – they’re just 90 mm in outside diameter compared to 300 mm for standard ducting.
The SDS’s narrow ducts open to equally discreet 50 mm diameter diffusers. The diffusers can be placed in the ceiling, walls or floor and are easily mistaken for halogen downlights when installed.
Even the Small Duct Systems’s air-handler components offer complete design flexibility. They can be stacked horizontally or vertically and can be located anywhere in the house you choose.
You can hide them in the cellar, under the stairs, or even in a wardrobe without affecting the system’s performance.
