414352	2005-12-21 09:22:00	I fitted 10" (250 mm) fans to the utility rooms here, ducted with 10" galv steel chimneys straight through the roof or a grill straight out the wall. Slowed them down with a 40 watt lamp in series, so while the have a very high CFM extraction, they are also very quiet. They will extract a room in about 30 seconds ....	godfather (25)

Too many curries and too much beer can cause you to need a 30-second refresh GF.:D That's about as long as the average person can hold their breath before passing out; for one reason or another.:p Cheers Billy 8-{)	Billy T (70)
414354	2005-12-21 09:37:00	But both the curry and the beer probably have gluten in them, so that's strictly off limits for me ... Anyway, I don't even need the fans. Its either that I am so pure, or that radiation treatment has destroyed all sense of smell. Possibly the latter, regretfully, but how would I actually know?	godfather (25)
414355	2005-12-21 16:01:00	Thanks for replies folks. The purpose of the fans is to rid the bathrooms of the water vapour from the showers, not smells! I kinda doubt that the ducting is a problem because the path seems to be pretty short to outside. And dust or other clogging is unlikely cos the house is only about a year old. If replacement fans are 100 bucks plus fitting I might just bother about it closer to winter. Cheers.	Greg (193)
414356	2005-12-21 17:05:00	We have an extractor fan on the ceiling ducted outside and it isn't very good. I think the fan is limited to stop it making too much noise. Neighbour has just had extractor fitted that is fan unit inline with ducting, much better! The fan is suspended in ceiling and doesn't seem to be as noisy.	PaulD (232)

And dust or other clogging is unlikely cos the house is only about a year old. Probably a bad choice of (cheap) extractor fan by the architect/builder/electrician Greg. Do some research before replacing by wandering in to your nearest electrical wholesaler or talking to a good electrician for some sound advice before buying. If you don't know a good electrician, phone the Electrical Contractors Association (ECANZ) on 0800 50 66 88 and ask them to recommend a member near your home. Cheers Billy 8-{)	Billy T (70)

A couple of years after it was installed we got concerned that the water being extracted into the roof space may cause problems there so we got some ducting and vented it outside instead . It became utterly useless . It couldn't suck the skin off a rice pudding so we went back to the other method and just keep an eye on how things are up there . The roof is unlined concrete tiles so it's pretty airy and no sign of mould has been detected yet . A cottage we have just been staying in had a good extractor fan in the bathroom that was vented outside so it is possible . It did sound like a jumbo taking off though . . .	FoxyMX (5)
414360	2005-12-21 21:39:00	the trouble with a lot of the fans (this actualy applies to pc fans as well) is they are made to be quiet, unfortunatly this means they do not like backpressure one little bit. even a small run will cause to much back pressure. the fans simply run to slow and have the wrong blade pitch to handle any decent pressure. a customer of mine had a simlar problem with a range hood. he ripped the standard vent out and used a big plastic drain pipe. works sweet as :) also i remeber many years ago a tech worked out the pipeing requirements for a dryer in an apartment buidling. it would have required a 10ft diameter outlet pipe !	tweak'e (69)
