## Description

Range of 100mm domestic axial extract fans for wall or ceiling installations, designed to solve ventilation problems in utility rooms and bathrooms. Fitted with motors mounted on silent elastic blocks, the fans deliver incredibly silent running and exceptional performance with stylish features. Adjustable Timer: After disconnection, shut off time can be delayed between 1 and 30 minutes. Adjustable Humidity Sensor: The level of humidity for the bathroom can be chosen from between 60% and 90% RH. The extract fan will continue to work long enough to reach the selected level.

Review: great product - I bought this as a replacement as I've remodelled the bathroom. Easy enough setup & the timer set at 15mins goes off as you'd expect unless there's still humidity in the room, then it carries on until it hit the humidity you've set it to. What I like about it is that it comes on when you have a bath or shower even if you don't have the light on as the sensor picks up a change in humidity. It's inobtrusive too having a plain front & a small light indicating whether or not it's on. The colour of the light can be changed by sliding out the coloured plastic & replacing it with one of three other colours. It's only been fitted a week so I don't know about longevity but so far so good... oh & it's quieter than the last one so I can't really hear it when I'm out of the bathroom.. happy days!
Review: Nice looking, really quite and took 5 minutes to install - Very pleased with the extractor fan

### ⭐ One stars because it looks ok, but performs terribly
*by T***Y on 15 August 2023*

I bought this to replace the silent 100 humidity fan that had died after 10 good years of service in a very humid ensuite. We bought it because it looked nicer than the standard design, thinking it would give similar extraction rates. It doesn’t. My ensuite was wetter than an otters pocket after an hour of this fan running, I’ve spent the last 4 months trying every combination of switches to get it extract without running 24hrs a day and dry out my ensuite. This is simply the best example of taking something that works perfectly and over engineering it. The electronic control is rubbish, far too many choices, of which non work. It’s so wet in my ensuite the door swelled up and you could hardly open and close it. Gave up in the end and replaced it with a standard silent 100 humidistat version, which dries my ensuite out within hours of finishing a shower.
