We supply plastic ducting from 100mm to 150mm diameter in white from stock. Other special duct materials, finishes and size components are available, along with a full range of fittings and ancillary components - please call to discuss your specific custom requirements. 

Note: Round Ducting: Our straight lengths of plastic duct round tubes are 'female' i.e. duct fittings such as bends and reducers are 'male' and generally slip inside the duct tube. To connect two 'male' duct ends together use a 'female' cut length of straight duct / tube.

Note: Rectangular Ducting:  Our straight lengths of plastic rectangular ducting are 'male' i.e. duct fittings such as bends and reducers are 'female' and generally slip over the straight duct. To connect two 'female' duct ends together use a 'male' cut length of straight ducting.

1. The length of ducting and number of bends will effect performance and should therefore be kept to a minimum.
2. Long runs of flexible ducting are not recommended for use on cooker hoods.
3. Plastic Ducting components have a simple push fit connection. Flat channel can be easily cut to length using a hacksaw.
4. 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.
5. When installing a circular through-the-wall duct a core drill can be used.
6. Ducting passing through an unheated areas such as roof voids should be insulated to minimise condensate formation and must include a condensation trap and means of running off condensate. 
7. Vertical ducts should be fitted with a condensation trap for low power systems and a weather proof cowl of sufficient free area for the air volume.
8. Horizontal ducts should fall away from the fan unit.
9. Choice of the right system will ensure quiet and efficient operation of fans and or cooker hoods
10. All internal system parts manufactured with self-extinguishing materials to meet fire retardency standard UL94V2
11. Plastic materials do not corrode leading to a clean and long lasting life
12. Wall outlets are made with UV stable materials to delay colour fade
13. The choice of ducting system will depend on a number of factors including: the power of the cooker hood or fan to be connected to, its location, the configuration of the duct run, the space available and others.
14. Maximum working temperature for rigid PVC duct is 60^oC
