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

Great fan. Just purchased this to replace the previous identical one that has lasted 13 years. Love the aesthetic design and relatively silent operation. Iris opening is clever.Had to contact the manufacturer for help and it was easy and they were great.

Very efficient fan , quiet , I love the automatic opening and closing . Stops backdraft that I had from my previous fan and can't hear the constant clacking from the cover outside when windy . Easy to install . Would recommend

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.

Brilliant, had one in a property 9 years ago, worked well then, still does, sucks air out, stops any draughts coming in.

Modern looking. Unobtrusive, sleek. I am really pleased wit the look and performance of this. It doesn't make too much noise either. We have the run-on timer installed. Would recommend.

Very capable quiet fan. You need to order the timer sensor separately. I bought the humidity and timer module. Its very straight forward to install. Mine was a replacement fan. On initial installation my speed configuration was not achieved by the fan. This was the result of the ventilation exhaust pipe being too long. With support from the manufacturer we were able to resolve this. We moved its location to an outside wall and it performed brilliantly. Really useful feature it can be set so the fan doesn’t come on between 10:00 pm and 08:00 just the light. Very low power consumption, very quiet. I use the humidity sensor to activate the fan. This happens even with the light off.

Easy to install, works well. Recommend to use with the moisture sensor for best results!

Noisy for an expensive fan.A lot of vibration, don’t understand why it has not been balanced at this cost.Much noisier then spec at 56dB.Orifice takes ages to open.Having said that, it works really well as a fan.
