Hi. Could I use this system on a 3mtr run with an extractor fan to vent a small cloak room?
-
QHi. Could I use this system on a 3mtr run with an extractor fan to vent a small cloak room?answer nowA Hello JulieThe conversion from 100mm round to the slimline ducting reduces the airflow capability by about 14% which is no big deal provided the fan you are using for the cloakroom is suitable for the long duct run.It is the type of fan that will determine whether the system will work for your circumstances.

I have today received 4 no. QS4113 adaptors and some 204 ducting QS297 and discovered that despite the adaptor having a larger socket end on the rectangular section, it will not fit the ducting. Is there some form of internal spigot to connect the 2 internally, or do I need the socket connector?

David Jeanneret (verified owner) –
Does what it says. Nice, bright white. the square profile fits fairly well with the Verpls ducting kit I got from Magnet Kitchens
Barbara Colaco (verified owner) –
Sturdy plastic. If using in a visible position note that it is a different colour white to the other components of this system.

Thank you so much to the team at i-sells. i had a problem to overcome and the team helped me with the specification and the the delivery in good time. despite me making a mistake with ordering (forgetting to order a part)and separately a part missing from the order, the following day the team got the missing part from my order and the bits i didnt order in the first place and got them to me within 24 hours (which i wasnt expecting at all). I have been so impressed with I-sells that i have mentioned this to all of my friends and business contacts. i dont often need this kind of service but i cant believe how efficient things have been. thanks so much guys, our kitchen and house does not now stink of cooking and smells thanks to the 220 megaduct and 6 flat to round etc. drilling the hole was another matter but quite a laugh nevertheless, regards mark j, happy customer !!
Robert Talbot (verified owner) –
This fitting is difficult to find elsewhere and of good quality.
Thomas Black (verified owner) –
Good quality. Worked fine to change from round hose to rectangular hose.
Peter Dinning (verified owner) –
Its ducting. What more can you say!
Kuldip Chexal (verified owner) –
All parts of the 125 set up worked very well. Very satisfied.
Robert Hudson (verified owner) –
Exactly what I expected – being used for large extractor unit above 4 oven Aga. Hardest part was drilling rectangular hole in wall. For technical reasons we could not put a 150mm circular tube through wall – shame as it would have made our life easier.
