Review: Looks good and excellent extraction rate - There were no problems with delivery and the unit arrived within expected dates. I replaced like for like. So the installation was fairly straightforward. The original Airflow 30 lasted for 7 years. I think it would have lasted longer if I had carried out more regular maintenance by carefully cleaning the rotary blades every 3 months or so. The use of baby powder after a shower is the main problem. The fan is more expensive than other fans, but it has neat styling, no back draught when closed, and very good extraction power. On the down side you have to purchase a separate timer unit if you want the fan to continue operating after it is switched off. The timer from my original fan worked without any problems. If you are thinking of replacing an existing 100mm fan, just be aware that the hole diameter in the ceiling will need to be increased, although the fan still connects to a 100mm flexible extraction hose. Do your own research are check out installation videos.
Review: Lovely and powerful - This fan is quite, quite excellent: When taking a shower, the humidity module (I installed this fan with the humidy-and-timer module, purchased separately but also from desertcart) automatically turns on the fan and by the time I step out of the shower the fan has extracted enough humidity from the bathroom that the mirror isn't even steamed up. This is in a 4m x 4m bathroom. Also, the slowly opening and closing iris mechanism has a delightful look to it. One word of caution: while the fan can be fitted surface-mounted using the "contoured skirt" provided, it looks rather ugly, protruding from the wall by about 9cm or so. To look good, it really needs to be fitted flush to the wall. In my case, that involved removing a chunk of wall around the existing vent hole to provide enough space for the fan's motor housing to be seated inside (15cm across by 8cm deep). Since every local builder I approached had core drills which could only cut a NEW vent hole, rather than widening an existing one, that meant a few hours work myself with cold chisels, brick bolsters, masonry drills and a masonry hammer. Definitely worth doing, however, as the fan now looks good and works extremely well.

## Questions & Answers

**Q: what are the measurements to fit in the wall/ceiling?**
A: A 100mm Diameter CIrcle is required to fit the fan to the wall/ceiling. The actual dimensions of the fan are 147mm x 147mm x 131mm. They are also available in 120mm and 150mm diameter circle mount.

**Q: does this have Installed duct, so no condensation build up ruins the fan.  Since I want to put into bathroom/toilet ceiling that goes up to loft**
A: The Quietair fans do not come with any ducting within the box, however the fans must be installed with ducting. The ducting will run between the fan to suitable external grill or roof terminal.A condensation trap should be fitted above the fan, this is to stop any condensate formed within the ducting from running back into the fan and potentially causing damage.

**Q: Our qt100ht has only had just 2yrs use and stopped working. airflow what are our options?**
A: They do stop working like most fans after a few year but the life can be extended if you 
Keep the fan clean by removing dust. Leaving dust on reduces efficiency and upsets balance. May even work again after this.
Don't leave light on for days as the fan keeps working and the bearings get hot

**Q: What is the sound level in dB at the highest speed?**
A: From the manufacturer’s website ‘ Sound pressure 25/30 dB(A) @ 3m’. I assume the 2 figures refer to the 75/90m3/hr modes. I have a number of these units fitted in my house ...the lower noise/volume/speed is indeed quiet but the higher noise/volume/speed mode is of course noisier and I would hazard annoying at night if you install in an en-suite. I have a unit in my en-suite which is set to trigger at low noise/volume/speed on humidity and higher when linked to turning on via ceiling lights. As I have low-level led lights turning on via a motion sensor at night, I can ensure that I don’t trigger the high-speed fan mode and disturb my light-sleeping wife.

### ⭐⭐⭐⭐ Excellent fan, maybe just unlucky that the first one failed.
*by P***N on 18 July 2016*

This is superb. Wanted to replace a noisy 100mm fan during a bathroom refurb. This 120mm unit extracts loads of air, is very quiet, and also looks neat. Has a 2-minute delay, which is good, so doesn't go on every time you make a quick visit. Plus a humidistat, I now have a 2m square wet room without windows, and when when I'm done, I turn off the light, the atmosphere is back to normal within 2-hours, and the room feels dry and airy. Revised my review from 5 to 4 stars, as the fan failed after 18-months of use. Just wouldn't come on, and the room stayed warm and stuffy. Interestingly, the original fan actually got quieter over time, to the point where I sometimes removed the cover plate to check it was still working. It usually was, until it wasn't. Bought a replacement so easy to swap, four screws and 3 push-in wires. Maybe just unlucky with the original and the replacement may last for 20-years?!? Annoying that the replacement (via Electricals247) had all four plastic clips broken on the cover plate. I could use the original cover instead, but a broken product should not have been dispatched. The rattling in the box was a clue!
