Difference between kitchen and bathroom fan?

Aug 04, 2007 18 Replies

Hi,



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.



TIA

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 tolerated.

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.

Bigger mainly. 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 [1] 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 [1]. [1] Assuming this is a new or extended kitchen, otherwise there is no requirement to meet any particular extract rate.

Some context would help. This is usenet and you're posting through a broken website.

This might assist you with posting to a newsgroup, albeit through a website:

Ah, memories.

Shame the very late reply is a load of bollocks, though.

Hmm, it has to be that sorting on their site ignores years for some weird reason, maybe the forums have a way of archiving every year on dead threads, but of course this would be unlikely to workon usenet. Brian

replying to Bingo, Amanda Electrics wrote: yeah, that's not really accurate. You can buy bathroom ones without a timer function. The difference is generally the size of the ducting which allows a greater extraction rate for what would be expected to be a larger room.

A timer is only relevant for an internal bathroom where you have to turn the light on to use it - the fan comes on and stays on for five minutes or so after you leave. For a bathroom with a window you want one that you turn on manually, preferably a two speed job so you can leave it on low (and quiet) most of the time and only turn it to full (and noisy) when required.
