Kair Ducting System 100mm is a range of both rigid and flexible PVC ducting.
The length of ducting and number of bends will effect performance and should therefore be kept to a minimum.
Long runs of flexible duct are not recommended for use on cooker hoods.
Ducting components have a simple push fit connection. Flat channel can be easily cut to length using a hacksaw.
When installing a rectangular to round adaptor, it is important that the flat side is fixed uppermost. The flap operation of a grille/fan would otherwise be obstructed.
When installing a circular through-the-wall duct a core drill can be used.
Ducts passing through an unheated roof void should be insulated to minimise condensate formation and must include a condensation trap and means of running off condensate.
Vertical ducts should be fitted with a condensation trap and a weather proof cowl of sufficient free area for the air volume.
Horizontal ducts should fall away from the fan unit.
