Hand-held air compressor

[JayB]

Hey guys,
I'm looking for an easy and portable way to remove dust from computers. At the moment I unplug them and carry the in the garage and clean them with a huge compressor. But that is annoying, so I was looking for a portable thing. Canned air expensive and I always need to order new ones, that isn't the solution. I was thinking about a blow-dryer thing without the heat and with more power. Do such things exist?

This might be a super dumb idea, but what if you take a small engine, attach a big electric motor to the crank, and an air tank to the exhaust. I mean that's basically all a normal compressor is, an engine that doesn't burn anything.

Buy another compressor for wherever your rigs are, you can get portable ones like 1.5-2HP engines with smaller tanks, I would defo use a filter with it though to try and get rid of any moisture before blowing on your rigs... and obviously use a lower psi so you don't break anything.
