Kair System 100 (SYS-100) 110mm x 54mm rectangular ducting is designed for short duct runs and it can be easily concealed due to its low profile. It is perfect for installations requiring low extraction rates such as bathrooms, toilets, and utility rooms. It can be flush-fitted against ceilings and walls and can be concealed above wall units or inside ceiling voids.

Hello, I have a need to extract a 12.5 cubic metre bathroom, with oblong ducting of 10.1 metres in length with 9, 90 bends (around support steels) what do you recommend for an in-line fan and size of ducting Thanks Tony
Hi. That is a very long duct run, and a lot of 90 degree bends. They will cause a lot of restriction to air flow. The only unit that may be able to deal with that, would be the Nuaire MEVDC2. They are continuous running fans. If you can lessen the amount of 90s that would help, but it is still a long duct run.
To follow on from today’s answer, Thankyou. I could reduce the number of bends to 3 and the run length to 8m? I am extracting a rarely used shower room through a large garage of 77 cubic metre, could I just extract through the wall to this garage open space?
Hi Anthony. It isn't recommended to vent directly into a garage, as you will be filling the garage with extra humidity.
Hi Marc, thanks for your help and patience. Just another couple of questions, in the duct run of 8m I can put the extract fan anywhere, what difference does it make near the bathroom or the outside? Also if I extract into the garage I didn’t mention I also have quite a powerful extract fan from the garage to outside? Regards Tony
To be honest, it wouldn't make too much difference. I generally suggest installing it halfway. If you have an extract fan in the garage, then that should be ok, however, if you come to sell the house, it may get picked up, as it won't meet building regs.
