Devola DVQTF100T 100mm Axial Designer Bathroom Extractor Fan with Timer (4 inch, Quiet Tile Fan) – Made in Britain
Product description
Key points
If you’re trying to keep a bathroom (or other damp-prone room) from feeling stale, an extractor fan with a timer can be the sensible upgrade. The Devola DVQTF100T is a 100mm axial designer extractor fan with an overrun time delay, so it can continue running after you’ve finished using the room. That small behaviour change matters in practice: it helps move moist air out rather than letting it sit around while condensation does its thing.
On paper, this model also leans into quiet, day-to-day usability and straightforward ownership. It’s designed to be easy to install and simple to clean, includes a built-in backdraft shutter, and comes with a protective cover to block visibility into the fan opening. It’s “Made in Britain” too, and there’s a stated 5-year warranty—those are the kind of details that tend to matter if you’d rather not treat ventilation as a replace-every-few-years job.
That said, it’s not perfect for every scenario. If your ducting setup or room ventilation needs are unusual, you’ll want to sanity-check the size guidance and airflow figure before ordering. Also, “quiet” is relative—this is positioned as a quiet tile extractor fan, but without noise level numbers in the details provided, you’ll only know how it matches your expectations once installed.
The essentials
The DVQTF100T is built for ventilation in rooms where humidity and odours are common. It uses an individually adjustable run-on timer (2–30 minutes), giving you control over how long it stays active after the pull-through event. If you tend to forget to switch things off promptly, the overrun approach is a practical way to reduce damp build-up.
It’s described as having a powerful extraction rate of 85 m³/h, with a focus on removing humidity and odours efficiently. Pair that with the backdraft shutter, and you get protection against unwanted air flowing back when the fan isn’t running.
A quick micro-scenario: imagine a shower in a small bathroom. You switch the fan on with the light (or a bathroom switch), the fan extracts moisture while you’re in there, then continues for your chosen overrun time. When you come back later, the room air should feel fresher—less that “wet tiles and lingering smell” feeling.
What stands out
A few things in the description feel deliberately chosen for real-world comfort and ownership.
First, the built-in backdraft protection. It’s said to use translucent flexible flaps on the rear spigot to stop unwanted air from flowing back. The same system is also described as reducing heat loss when the fan is in standby, which is a nice bonus in colder months.
Second, the installer/cleanability angle. The fan is presented as easy to install and easy to clean, which is often the difference between a fan that gets used properly and one that becomes annoying.
Third, the “designer” approach: it includes a protective cover that blocks visibility into the fan opening. That’s not essential for ventilation performance, but it can make the finished installation feel tidier.
Finally, the brand details: it’s fitted with a premium German-engineered motor and is made in Britain. Backed by a 5-year warranty, it’s aimed at buyers who want longer-term confidence rather than a short-term throwaway.

Where it shines
This fan looks best suited to straightforward ventilation for high-humidity rooms, especially where you want the fan to keep working briefly after the room is used.
The provided room-size guidance gives a practical starting point: it’s indicated as suitable for WC (3–4 m²), bathroom (3–9 m²), bedroom (7–13 m²), kitchen (3–7 m²), and office (5–13 m²). If your room falls into one of those ranges, you’re likely thinking along the right lines.
It also makes sense if you value basic protection features. The backdraft shutter is there to reduce unwanted airflow back into the room when the fan isn’t running, and the protective cover helps keep the installation more concealed.
What to watch before you buy
The main limitation to keep in mind is fit-for-purpose certainty. The description gives a selection of room-size ranges, but it doesn’t explain ducting length, ceiling height, extraction duct requirements, or how your existing ventilation setup behaves. If your layout is awkward or ventilation is already borderline, you may want to double-check the suitability based on your install conditions.
Also, while it’s described as a quiet tile extractor fan, the details provided don’t list decibel or noise figures. If you’re extremely noise-sensitive (e.g., bedrooms with night-time use), it’s worth being cautious and confirming what “quiet” means for your use case.
One more practical note: overrun timing is adjustable (2–30 minutes), but choosing a longer run-on isn’t always “better” for every household. Depending on your humidity levels and how the room is ventilated otherwise, you may need a bit of trial and error with the timer setting.
Is it worth it?
Worth buying if you want a 100mm axial bathroom extractor fan with an adjustable run-on timer, backed by a stated 5-year warranty, and you’d appreciate backdraft protection and a concealed fan opening for a cleaner look.
It may not be the best choice if you’re dealing with a ventilation setup that falls outside the stated room-size guidance, or if you need specific noise-performance data to feel confident before installing.
If you like the idea of a fan that does the “finish the job” bit after you’ve left the room, the DVQTF100T’s timer and backdraft shutter approach fits neatly into everyday living. If you simply need the simplest possible extraction with no interest in post-use extraction timing, you could feel that the extra features are more than you need.
