If you cooker hood has a 150mm spigot then I would suggest the ducting stays at 150mm as 1 you may impede your warranty and 2 you will restrict the airflow. If you have a 102mm drill hole already this can be made bigger to 152mm then you would require flashing and a HU-Cowl 150mm. If I can help any further please do not hesitate to contact meKind RegardsAnita

Please confirm free area to grille - it is intended to use this as an intake for make up air to a solid fuel fire - does it come with an insect mesh?

QPlease confirm free area to grille - it is intended to use this as an intake for make up air to a solid fuel fire - does it come with an insect mesh?answer nowA Hi Richard. Thanks for your question. This doesnt have a mesh unfortunately. It is intended for exhaust only, and not intake, so there are no free air specifications for it. Our products are for air ventilation systems such as Extractor fans and heat recovery units.Kindest regards, Marc.
We have an 6 underground duct in plastic that measures 160mm in outside diameter. I need help to select the correctly sized GALHU to fit. Can you confirm which model will fit? The GALHU-160 may work, but you do not show the ID of this unit for me to check. Can you confirm this please?

The GALHU-160 may work, but you do not show the ID of this unit for me to check. Can you confirm this please?answer nowA Hello ChristianThank you for your question. As ventilation duct is different to drainage i do not think any of our products will do your application. The Drainage Center maybe able to help you further. Kind RegardsAnita

My builder has used Polypipe 160mm (outside diameter, actually between 159mm & 160mm) drain pipe for the roof penetration. Is the 160mm the correct size or is it to fit a 160 nominal duct that is actually bigger?
Thanks

Thanksanswer nowA Hi MatthewThe product description says it is female connection yet the spec says diameter 160mm, I have just measured the same product in 150mm and the actual diameter is 155mm on that basis the 160mm should fit over the polypipe?If not the sleeve below should be suitable.http://www.i-sells.co.uk/galvanised-safe-female-sleeve-connector-160mm?ref=also_purchased#tabBox
Is this cowl suitable with the above hose? I need to drop the hose (unsupported) down a chimney to connect to a kitchen extractor. If not suitable - which hose would work?
-
QIs this cowl suitable with the above hose? I need to drop the hose (unsupported) down a chimney to connect to a kitchen extractor. If not suitable - which hose would work?answer nowA Hello Stephen Thank you for your question. The cowl has to be riveted or screwed to the duct work so flexible hose will not do the application. You will require rigid pipe which comes in 1&2mtr lengths in plastic and 3mtr lengths in metal. If you require any further assistance please do not hesitate to contact me on 0208 463 9683 Kind Regards Anita
I have a short length of 150mm plastic soil pipe inserted into a flat roof to extract from a kitchen ceiling extractor. would this product be suitable to connect to the plastic pipe externally.

QI have a short length of 150mm plastic soil pipe inserted into a flat roof to extract from a kitchen ceiling extractor. would this product be suitable to connect to the plastic pipe externally.answer nowA Hello Eugene, This item is designed to connect to 150mm Spiral ducting or 150mm plastic ventilation piping. I could not confirm whether it would be suitable to connect to your particular plastic pipe, but it does fit over our 150mm pipe (DUCVKC670) which has an outer diameter of 154mm so if your pipe has a matching diameter it might fit.Kind regards, [email protected]
