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 .

Measured from what distance ? Noise Measured installed in duct or free standing detached ?** A: Measured at 3m. This is a generic fan design, they are all the same. The 33W version is up to 56dBA at 1m Euro-spec. **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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Powerful quiet quality extractor *by G***N on 9 February 2026* 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 .
