Rangehood Solutions does not support the use of flexible ducting on any of our rangehood installations. We aim to duct all rangehoods with solid galvanised or stainless round 150/125mm diameter tubing. This solid ducting is ideal for long straight runs where a minimum of bends or offsets in the rangehoods ducting run are needed.
When bends or offsets are unavoidable in the ducting run we will use 150/125mm "semi rigid" ducting. This is an aluminium smooth internal bore product which allows high unrestricted airflow around any radius of bend/offset. We can also offer a rectangle PVC boxed ducting for in wall frame or limited space installations. This option is also available in the equivalent of 150/125mm sizes with a variety of rectangle to round adaption fittings, along with horizontal and vertical offset options.
Some advantages of using the high spec ducting products mentioned above over the sub-standard flexible ducting used by some installers are:
All ducting is flame and rodent proof.All ducting has a smooth internal bore allowing a maximum unrestricted airflow from the rangehood fan/motor to the duct outlet.An unrestricted airflow in turn creates a quieter, more efficient performing rangehood at kitchen level.
