FANTRONIX NAZAIR White 100 mm Quiet Powerful Bathroom Extractor Fan with Humidity Sensor Wall Ceiling Mounted Ventilation Damp Environment Control for 100 mm Ducting Silent Toilet Shower Ventilator

I used this to replace a more expensive branded similar fan - twice I had to replace that because it became noisy. I installed the Fantronix model a few weeks ago and so far all is good. It is quiet and works well. The humidity sensor is adjustable in the same way as the timer, but is obviously trial and error as to the right setting. I didn't change my setting and occasionally I get the fan turning itself on in the night. I would like to change it but I can not get the casing to open, no matter how hard I try, so my advice when you install it would be to not fully close the casing until you are happy with the timer and humidity settings.

Works well. Quiet until you put the cover on - it starts to emit a loud whine as the cover gets near to the fan which remains after it is attached. Tolerable but a shame as the fan itself is quiet!

Removed the old Fan and connected 2 wires for this one. I wanted a manual pull string one as the auto models seem to stay on for ever.Pull the string an orange light comes on. Pull the string one more time and it runs for 30 minutes ( That's the maximum time the timer runs for.Pleased with my purchase.

I bought this fan to replace the 15 year old fan in our bathroom which had become noisy. The fan arrived on time and was easily fitted but what a disappointment with the noise level of this fan. It is advertised as 25 Decibels but in fact when running it is 65 decibels and a lot noisier than our old fan was. Other than the noise it works perfectly fine. I would have given 5 stars if it had been as quiet as advertised

Works well neat and quiet - its starts slow and speed is dependant on moisture in room - very clever.

This was a very easy to install fan. It does exactly what I needed to do with the humidity sensor settings and timer delay.I had a little trouble fitting it through the duct as the rear of the fan is not completely circle, there is a raised part on thr back of the fan which means it will not easily fit into a 100mm duct.

Highly recommended

This has only been in use a couple of months and this is what happened. Return window closed and left with no fan and damage to ceiling. Not impressed
