bought a Manrose 150mm/6" extractor fan from Screwfix to use in the kitchen.
Having finally (after a week of man flu) got round to opening the package I
see that the fan is labelled "For Bathrooms and Toilets".
So what is the difference?
Is a kitchen fan a higher extraction rate?
This is rated at up to 230m3 per hour.
Could it be that bathroom fans are designed to cope with more moist air?

...or kitchen fans can cope with more airborne fat?
I dont know either, but would expect noise. Brief bathroom exposure to
noise is one thing, but continuous noise in the kitchen would not be
Bathroom one will need to be IP24 or better for fitting in zones.
Kitchen one has less stringent requirements, and would just have
to be IP2X like any other appliance anywhere else.

Or neither. Stop guessing.
IIRC 170 l/m is the lowest a kitchen fan can be. I forget. I did check
it out and big ones were kosher for the kitchen little ones for the bogs.

230m^3/hr equates to 63.9 litres/second, which is only just over the
minimum requirement  for a kitchen fan of 60 litres/sec (unless
it's in a cooker hood or directly over the hob). Once you start
adding in the resistance of any ducting into that, you could quickly
end up with a fan that might not meet Building Regulations .
 Assuming this is a new or extended kitchen, otherwise there is no
requirement to meet any particular extract rate.
