## 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: Great extractor fan, but makes sure you have enough wire to reach the connectors - I bought this as a replacement for an iCON 15, which failed. I didn't bother trying to fix it as I'd been looking to upgrade it anyway due to condensation issues in the shower room. This is almost twice as powerful and isn't noticeably louder than it's smaller cousin. In operation, it works really well at removing the steam from our shower room. Definitely an improvement on the smaller model and well worth the extra money. I bought this model as I wanted something that would fit the existing 100mm duct. Just be aware that if you want this to be flush mounted then the first part of the duct needs to be bored out to a larger diameter to accommodate the rear element of the fan. As a result, I mounted it with the skirting supplied, which then pushes the fan about 5cm further out of the wall. Not an issue, but it does mean that the power cable will also need to be that much longer when connecting it. Therefore if you have a short cable coming out of a tiled wall, you'll need to be able to extend it. Last thing, if you want this fan to run on (as per building regs) then you'll need a control module to fit as well.

### ⭐⭐⭐⭐ noise level
*by R***2 on 5 May 2023*

All installed in a kitchen. It looks good and the function of opening and closing is good. My only issue is that it is quite noisy when fully open. Having said that it is no noisier than a conventional extraction fan although the reviews and blurb said it was reasonably quiet. Overall more things positive than otherwise.
