Concentric Ducting Reducer 100-125 mm
The 100-125 mm ducting reducer is a metal transition piece for connecting a 100 mm ventilation duct or fan to a 125 mm system. Handy when linking an existing 100 mm setup to newer 125 mm components, or when your fan and filter have different diameters. Sturdy metal construction. Order at plantandflower.be.
Ducting reducer 100–125 mm – bridge two diameters
The 100–125 mm ducting reducer bridges the gap between a 100 mm and a 125 mm ventilation system. Slide an Alu-Dec 102 mm duct on one side and a 127 mm duct on the other for an airtight transition.
When do you need a reducer?
Not all ventilation components share the same diameter. A 100 mm fan paired with a 125 mm carbon filter? An older system being extended with a larger format? The reducer makes that combination work without modifying the rest of your setup. Secure both sides with a hose clamp for a leak-free joint.
Compact reducer
The gap between 100 and 125 mm is small, making this reducer compact and virtually free of added air resistance. Ideal as a fitting in tight spaces or grow tents where every centimetre counts.

Does a ducting reducer cause airflow loss?
A reducer adds a small amount of resistance due to the diameter change. For a 100 to 125 mm transition the effect is minimal. Make sure the duct sits snugly on the reducer and does not kink at the connection for the best result.
