AirflowiCON 15 Bathroom Extractor Fan 19 l/s - 100mm/4 - Iris Open/Close Backdraught Shutter Tech - Energy Saving 9.4W - Optional Humidity, PIR & Timer Modules Sold Separately | 3-Years Warranty

The item was delivered within the time on the date stated in a nice paper bag which is recyclable and was carefully handed to me by the courier.. Fan fitted well is now installed and working perfectly, runs quietly and does the job it's designed for. It came without a timer module so I removed the module from the old fan and fitted it to the new fan. Job done!

I chose this fan because of the external backdraught system this was essential due to the storms we have had this year and in this unit you can see if it's open or closed. Well made unit, the timer module is simple to insert and the whole fan body was one part which allowed for easy fitting to the existing duct. 2 screws attached it to the ceiling and electric connections were standard screw down connectors. One fitted the backdraught cover simply twists on and is secured by a captive screw, not problems. In operation it's quiet and works a treat opening and closing perfectly. Nature provided a useful test with yet another storm and the anti backdraught worked well. In my opinion a good unit.

Like others, I bought this fan because of its iris shutter design. It was purchased to replace an existing extractor that had become noisy and had no shutters at all within its design. The lack of shutters meant a draught when the wind blew and caused a "pull" that you could feel in the whole house.So having seen one of these working in my Sister's house, it seemed to answer all the concerns and had no problem when deciding on which of the few shutter design extractors to go for.You buy this basic unit and it is an on/off fan with the power supply fed to it. So if you have a run-on timer unit, you will not get a run-on until you purchase the run-on timer module which is another £20 or so. In a way it's good because you're not buying something you may not need, but it would be good if the design of these modules were up to date (more on this later). Various modules are available; run-on, delay start and run-on, pull cord, movement sensing and humidistat. You choose the module you want and fit it in seconds.For your information, this is what happens without a module:1 - turn on the light, the fan starts but the shutter remains closed for 30 seconds.2 - After 30 seconds, the iris begins to open.3 - The iris takes around 30 seconds to open.4 - Turn off the light the fan stops.5 - Approx 60 seconds later the iris begins to close.6 - The iris takes around 30 seconds to close.So if this unit is used in a WC, the iris is unlikely to open fully before a "quick visit" is over and done with!Without the run-on timer, a "longer visit" will not be (shall we say) adequately ventilated!I ordered just the fan to begin with, it worked as above and eventually I decided to order a run-on timer. Prior to fitting the timer, it worked fine, but after fitting the fan made a grinding noise. I'm not sure where from, but no amount of adjustment to the timer or the wiring routing made a difference. After a half and hour of jiggling around with the shroud, I finally silenced it, but I can only assume fitting the timer pushes or pulls something out of flat. But now it's working perfectly and have no reason to believe it will not continue to do so.4 stars overall as it works well out of the box.3 stars for ease of installation. Given because I still believe if something is too difficult to install for the DIY minded then it shouldn't be sold on Amazon. And if you do, it should only come with user instructions. Supplying with fitting instructions suggests it is a DIY fitment. You have to choose, not dither.3 stars for value for money. Expensive if you need to add a module and employ an electrician to fit.Noise level. Quieter than my old Xpelair, but it's a 4" fan, and any fan smaller than 6" will be noisy as it had to spin faster to have any decent extraction. But it is quieter than many I've heard.As for physical installation, if you are replacing a square extractor, this will not cover up what the old extractor leaves. I had to fill the 4 screw holes and patch in the paint which I luckily had some still to hand.

Works well, & very nice design, thank you

Really easy to fit and the automatic open/close function means that you’re not left with a draft which I had with the fan this one replaced. All in all, good quality product and nice and quiet as well.

We replaced 4 x normal fans with these, after putting up with a lot of wind noise and losing heat in the colder months. No issues replacing fitting them, we barely hear the wind during storms and the smaller more affected room feels warmer.Initially the shutters did not always fully close, leaving a 2-3 mm gap, but a little silicone spray solved that.Tempted to knock of a star for the price and shutters not fully closing, but as they do what we wanted and there are no better options, 5 stars are fair.

We had an extension added to the house last year and the builder used the cheapest extractor fans he could get away with. Yes they have flappy external vents to try and limit any drafts coming into the house but they aren't great on a windy day. Then I came across these, what a great idea.You have the option to add timers and pull cords etc. I only needed a simple on\off so don't know too much about the modules.As for fitting and using the fan, pretty simple and I am not a DIY genius. Just follow the instructions and turn the mains off before you start going half-cocked with drill and screwdriver.The operation isn't silent but still a lot quieter than many fans of a similar size. They still have to move air and at a certain volume, so can't be too quiet. The absolute top thing for me is the 'cool' opening feature of the aperture. It opens after a few seconds, slowly to reveal the exit port. It's very geeky but very cool and practical. So far it keeps drafts out nicely.

Firstly, I've had issues with the motor being off-centre or something that caused the unit to produce a low frequency sound that reverberated through the whole house.Secondly, the wax piston that opens the blades is less effective over time, meaning it doesn't open fully. After a year, it now opens about 60%, and doesn't look like it's going to stop there.Good idea, but needs to be made better.
