That's my main usage of compressed air, where my shop intersects the 
computers.  Also, to force-dry things after they've been washed.

Because if it doesn't and that's a thing you'd need to pay for, I'd say 
that this probably isn't worth having.  There are very few air tools that 
don't have adequate or superior electric equivalents that you're liable to 
use in an electronics workshop.  Meanwhile, a $120 portable compressor is 
perfectly adequate for blowing off dust and poop once in a while and 
doesn't need special power or much in the way of maintenance.

Meanwhile most inexpensive hot-air soldering stations are self-contained, 
so you don't need regulated dried air.

A few years back I helped setup a makerspace nearby - one lesson learned 
was that kinds of tools that me and my friends could operate and maintain 
were sometimes beyond the skill, interest, or means of regular users. 
Just because it's free and a cool machine doesn't mean it's a good fit and 
sometimes it'll become more of a burden than a boon.
