## Description

From the manufacturer Airflow Developments Pioneers in Ventilation since 1955. For over 60 years, Airflow has been forging a path of leading innovation in the design and manufacture of ventilation systems and air measuring instruments. QuietAir Range The Whisper Quiet Fan QuietAir is a range of extremely quiet, elegant and discreet axial fans with various integral options that only activate when needed. These two speed fans can be controlled by remote switching, timer, humidity timer and motion sensor with timer. The second speed can be activated via an optional remote switch. By using exceptionally low energy, your carbon emissions and energy bills are reduced. The sleek and discrete design means there is no intrusion to your aesthetics. Up to 72 l/sec Integral flow straightener and back draught flap Low power consumption from only 5w. Delay start feature allows you to prevent fan from being activated when using the room for a quick visit. The delay start feature can be adjusted from 45 seconds to 2 minutes (excludes Basic models) The QuietAir fan enables the user to choose between one of two speed options, a low or a high. By using an independent switch, you can alternate between the two speeds. It has a high efficiency impeller for extraction through up to 10 meters of rigid ducting and still able to comply with the Building Regulations The QuietAir Range QuietAir 100 Toilet, Bathroom and En-suite The QuietAir 100mm is the quietest fan available complying with the latest Building Regulations Installed Performance requirements on both speeds, when ducted. The QuietAir 100 carries the Quiet Mark accreditation. 2021 - Quiet Mark Approval QuietAir 120 Toilet, Bathroom, Utility Room and kitchen (adjacent to the hob) The more powerful performing QuietAir 120mm is designed for larger wet rooms to provide extraction levels that exceed the requirements of the latest Building Regulations. The QuietAir 120 has been awarded the Quiet Mark accreditation for the kitchen category. QuietAir 150 Kitchen (Adjacent to the hob) The powerhouse of the range – the QuietAir 150 is ideal for kitchens and larger rooms whilst still achieving a low noise level for its size of only 35dB(A). Variable speed control is available for quick and easy adjustment of the flow rate.

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.

### ⭐⭐⭐⭐ 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!
