Quiet Extractor Fan, but at high extration rates

[IAN999]

Hi,

Hoping someone can help, Im after some extractor fans:

Kitchen - 550m3/hr extraction
Bathroom - Zone 1 110m3/hr extraction
Ensuite - Zone 1 110m3/hr extraction
Toilet - 45m3/hr extraction

Anyone give any advice on what the quietest extractor fans would be to fit the bill?

Thanks

Use inline ducted centrifugal fans, which can then be located away from the rooms they're being used to ventilate, thus reducing noise. The kitchen may be a little more tricky, as a high extraction rate is going to mean either larger ducting or faster airflow, the latter being likely to cause noise through air turbulence.

As you have a lot of rooms to ventilate, have you considered a whole house heat recovery unit?

For the kitchen, use an externally mounted fan, like this

Thanks

For many makers, including Silavent, you are limited on your choice of a bathroom 100mm fan that can shift 110m³/hr and is quiet.

The Silavent range can be viewed here

No, sorry, I don't. However, there's not a lot inside them to go wrong, so as long as you make sure that it's capable of giving your required extraction rates through whatever lengths of ducting will be required, I wouldn't expect any problems.

Ok no worries. If anyone else has experience of these (Heat Recovery Units) i'd be interested to hear your thoughts.

Prices are a bit steep if there's not a lot inside them
