Uses for canned air

Blowing dust off a vacuum cleaner when changing the dust bag
(outside). Plenty of situations were sucking works poorly (like
using a vacuum cleaner). Blowing dust off of tools and of course
the work area.







Found another one... Blowing out (actually in) the exhaust coils
on a room air conditioner. I won't know for sure until taking it
apart, but looks like it does a good job of removing debris from
the inside surface of the coils where the splasher fan throws
dusty water onto it.
