How do I reduce my ventilation ducting? Sometimes you install ventilation units but the diameter may be different from the ventilation ducting that was already installed before, or you change your VMC but the ducting used is in 125 and your ventilation unit is in 100mm, that's why ventilation manufacturers like Winflex Ventilation you can even buy multi-sized PVC duct reducers in the shape of cones, because some reducers can go from 80mm to 125mm on the same reducer.
Metal duct reducers: solid, sturdy duct reducers are the most widely used for ventilation installations.
PVC duct reducers: Lighter, easier to handle and more practical for your installation, they connect easily to air extractors and are compatible with PVC ventilation ducts in tube or rectangle form.
when to use a ventilation duct reducer? for all ventilation-related installations, whether in a warehouse, office or home, when connecting air extractors, in-line fans, air aerators, or for adapting any type of ventilation connector such as elbow, Y, T-branch for connection to industrial or domestic ventilation equipment.
