Not if you live in the Chesterfield / Alfreton areas of England. I've just spent the last 3 hours going from computer component supplier, to independent computer builder, to electrical component supplier, to hardware shop, back to computer component supplier etc etc ..... all in vain ..... :'(
The only place that had compressed air cannisters in a 10 mile radius of the house was a compressor supplier who couldn't guarantee that the contents would be moisture free as the cannisters he supplied were for airbrushes. I was even in one electrical component shop (a national chain) and when I asked if they sold compressed air cannisters the reply was "Why would we have them? ..... What have they to do with electronics?" :-/ :-/
There's one more possibility (without having to pay exorbitant delivery charges online) ....... a gas fitters .... they use compressed air to clean dust and dirt off pilot light contacts in gas boilers.
