It's all to do with emissions. Various pipes go into it, but exit underneath the canister and goes in to the chassis leg..
Can be done away with easily enough.

A charcoal filter is used as its very effective for filtering out the pollutants in the atmosphere, especially stuff from exhaust emissions such as hydrocarbons (benzene) and acid gases (sulphur dioxide) etc.
Charcoal is used in power station scrubber towers to cut emissions and its used by the military in gas masks. Just thought I'd add that useless bit of info for you!

It filters fuel out of air vents. From the fuel tank obviously but must be from other places too as there are so many pipes.
I would have thought when you drive air would go into the tank not out. When you fill the car with fuel all the air will vent round the filler so it does naught then.
I suppose the tank would warm up as you drive, warm fuel returning from the fuel regulator, warm air around it etc etc. In this case air would be vented from the tank, I guess this is when the charcoal filter takes fuel out.

It's part of the evaporative emissions control system. IIRC, It traps the nasty fuel vapours from the the fuel tank's evaporation pipe assembly and stores them until they can be safely injested into the engine when the ecu decides to trigger the canister purge valve.

Cheers Murray - sound good - So is it safe to do away with it or best not to ????
(Thinking of making new intake pipe with no connections for breathers etc) So I assume it is returned/purged back into intake pipe. Could it be vented to air safely ??
still
doh !
Cheers

Erm, can get a bit fumey just venting to air 
I think it's worth leaving in place meself, for just a few connectors here & there... never know what the next emissions test are going to be, and this does nothing (either way) to 'performance'.
Wouldn't really want to be too near the car for very long either with the sort of gases that can be produced with it not there - think all the nastiest ones that petrol produces - well, that's the stuff Mmmm nice carciogens

Hmmm....if you don't need the space the cannister area will give, then leave it in place.
If you're going down the 75mm inlet pipe route and want to use the later shape cars' heade tank, then remove it and the necessary pipework.
FWIW, i've not got the charcoal cannister anymore but haven't had any issues with *fumes*, smells or whatever under any circumstances, either at idle, cruising, or full blown mayhem!!
