900403774 Genuine 125mm 90 Degree Bend Adaptor Kit AR125B for Electrolux Group Rangehood Ducting

Need to turn a rangehood duct through a right angle? 900403774 is a genuine Electrolux 125mm 90 degree bend adaptor, sold as kit AR125B. It changes the direction of a 125mm duct run, for example from straight up out of the rangehood to horizontal toward an outside wall. Check that your rangehood outlet and ducting are 125mm before ordering, as duct sizes can't be mixed without a reducer.

Getting rangehood ducting right

A ducted rangehood can only extract as well as its ducting allows. Every bend adds resistance, so the aim is a short run with as few turns as possible, and a proper formed bend flows far better than a kinked flexible duct squeezed around a corner. Poor ducting shows up as a noisy fan, weak extraction, steam and cooking smells lingering in the kitchen, and grease settling on cupboards. Keeping the full 125mm size all the way through, without squashing it at the bend, helps the fan move air the way it was designed to.

Installing the bend

Switch the rangehood off at the wall before working near it. Push the bend firmly over or into the duct and outlet spigots, making sure it's the right way round for the airflow. Seal each joint with foil duct tape and support the duct so the bend's weight doesn't hang off the rangehood outlet. Any horizontal run should fall slightly toward the outside so condensation drains away from the rangehood.

Questions about this part

Can I use this bend with 150mm ducting?

No. This adaptor is for 125mm ducting. Mixing duct sizes without a proper reducer leaves gaps and restricts airflow, so measure your rangehood outlet and the duct you're using before ordering 900403774.
