VERY quiet ceiling mounted (min IP X4) bathroom fan recommendations?

[HappyHippyDad]

My very well off customer wants the most quiet ceiling mounted extractor fan there is. They have stipulated that cost is not a barrier and they just want something quiet.

I have used one extremely quiet fan in the past, but it simply didn't do it's job, so that's pointless. This fan still needs to be able to extract.

IPX4 as a minimum as it will be in Zone 2.

An in-line fan is not an option unfortunately as there is no space above.

Any recommendations?

Cheers

A lot has changed in the last year or so since the last post on this thread, these are the quietest fans I have found: Soler & Palau TD Silent In Line Fans - https://www.tlc-direct.co.uk/Main_Index/Ventilation_Index/Soler_TD_Silent/index.html and very effective they are too.

Never had a noise problem with in line fans. Five out of the six fans in the holiday cottages are 'ordinary' 100mm in line types of two or three different makes, and all are so silent that it is difficult to be sure they're working, without either listening carefully or the toilet tissue test.

Envirovent and s&p are the same fans, all their stuff seems crackin, function, aesthetics, price, im yet to find anything that is as well balanced
