Alu-Dec 250 mm 10 meter
The Alu-Dec 250 mm in a 10-meter roll is an extra-wide flexible aluminium duct for semi-professional and commercial ventilation systems. This diameter moves massive air volumes with minimal resistance and is intended for large grow facilities, greenhouses, workshops and storage buildings. Use a reducer for connection to 200 mm equipment. Order per roll at plantandflower.be.
Alu-Dec 250 mm flexible aluminium duct – 10 meters
The Alu-Dec 250 mm is one of the widest flexible ducts in our range. With 10 continuous meters and a 250 mm bore, it is engineered for setups that need to shift large volumes of air efficiently. Connect it to 200 mm equipment using a heavy-duty hose clamp and a 200-to-250 mm reducer.
Designed for commercial-scale projects
The 250 mm diameter goes beyond typical home grow setups. It serves commercial cultivation facilities running multiple rooms, greenhouses requiring active air distribution, large workshops with dust or fume extraction, and warehouses that need continuous airflow. The cross-sectional area is nearly 50% larger than a 203 mm duct, which translates directly into lower resistance and reduced energy costs for your fan.
Sitting between 203 mm and 315 mm
The 250 mm is the logical step up when 203 mm feels restrictive but 315 mm is overkill. Need a slightly smaller size? See the Alu-Dec 203 mm 10-meter roll. Going bigger? The Alu-Dec 315 mm is the next option.

When should I choose 250 mm ducting instead of 203 mm?
Move to 250 mm when your fan is rated above 1000 m³/h or when duct runs are long with multiple bends. The extra diameter keeps air speed low, which reduces noise and pressure loss. It is also the better choice for systems serving multiple rooms from a single extraction point.
