Review: Powerful quiet quality extractor - Powerful, quiet , well made , value for money , Easy peasy to wire in -no earth required just Live Neutral A second switched live ( activated when you switch on light inside shower cubicle ) Mounted mine on some foam ( kids play-mat type that you clip together ) ,just cut it to size job done . Thoughtful touches included were spare plastic tensioners for the straps that hold it to the cradle (should they break in use ) A dedicated plastic timer adjuster that is like a small screwdriver I have taped these to the fan in a bag so they are never lost and handy if I ever need to adjust timer. Overall very impressed it’s powerful , very quiet and the timer run on after you have switched off can be adjusted from zero to around 30 mins . I’m using this in really cold weather and there is zero steam escaping the shower cubicle the bathroom mirror does not even steam up and it clears any very very quickly . I suggest attaching the hoses with aluminium tape as it’s solid seals very well and is weatherproof , used by HVAC pipes fitters it’s good stuff . Also 100% recommend from me .
Review: Works really well - Brilliant, easy to install following instructions and works well, the mirrors used to be fully forged up with my old one and now don't show any fogging

## Questions & Answers

**Q: 27 dB noise. 
Measured from what distance ? 
Noise Measured installed in duct or free standing detached ?**
A: Measured at 3m.

**Q: What is the max temperature it can handle?**
A: According to the technical data of the fan the maximum temperature of the air removal is 60 degrees centigrade.

**Q: I'll need to reduce the outlet ducting of the fan from 100mm to 50mm to get it past obstructions to the soffit. Will this fan cope with that?**
A: That may reduce the extract rate or put strain on the fan motor.  Suggest putting I roof tile outlet or split outlet to y piece to two 50mm outlets.

**Q: Can it be used if you plug it straight into the outlet?**
A: You can wire a UK three pin plug and it will work great. Please search for 'fantronix hydroponic' in the search bar and you'll find our four, five, and six inch diameter fans available with a fitted UK plug.

### ⭐⭐⭐⭐⭐ Works really well
*by M***K on 11 January 2026*

Brilliant, easy to install following instructions and works well, the mirrors used to be fully forged up with my old one and now don't show any fogging

### ⭐⭐⭐⭐ Seems a good, economical fan.
*by E***D on 28 December 2025*

Easy to install. Seems to work fine. Warranty registration a bit bothersome - it's on the Blauberg site (so this is a Blauberg fan, which I'd guessed) and requires the serial number which I can't find on the box or paperwork, so will have to climb into the attic again for it. Note that the noise level per the fan rating isn't what is shown on the Amazon listing (others have commented on this), but it seems quiet enough.
