Compressed air....

[003]

I go through cans of compressed air like water. I keep having to buy more and more, and it adds up fast. Is there any kind of air compressor I could get or something so I don't have to keep buying cans? If not, is there some online vendor that sells cans on the cheap? Also, the stuff in the cans is not really compressed "air", it is difluoroethane. Is there some kind of advantage to this rather than just plain compressed air, or oxygen?

Depends. What do you need it for?

 

[003]

Dusting and cleaning things. Inside my computer, hard to reach areas, etc..

Buy a foot-operated blower or hand rocket blower.

Oxygen and nitrogen (the two main components of atmospheric air, of course) both require very low temperatures/high pressures to liquefy and maintain a liquid state. Obviously it's simply not practical to use air in this application, so substances without such extreme requirements, such as difluoroethane, are employed.

Plus, you know, you can't get that high off of air.

I made myself a blower-offer attatchment for a paintball CO2 bottle. As I have a 50lb bulk CO2 tank in my closet, this is quite efficient.

why not use tiny keyboard vacuums? Compress air pushes dust from point A to point B.

Just get a little cheap electrically powered compressor with a tank, like this:

Craftsman Compressor

Get a simple hose and this attachment: Nozzle Attachment

Or for a $100, get the compressor, hose and the nozzle attachment in one pack: Craftsman All-In-One

o.O I'm a little paranoid about pressurized tanks so I don't think I'd ever keep on in the house ('sides cooking gas of course, out of necessity), much less in my bedroom

Read about tanks exploding and killing people a little too often the past few years o.o

Save yourself some money and inhale deeply, then exhale sharply, adjusting your lips to increase or decrease directional air pressure. Not only is it free, but you will improve your cardiovascular and pulmonary efficiency. Soon you will be able to blow houses down, just like the big bad wolf. Even the brick one.

I've seen an exceedingly tiny compressor the size of a blender. I'm thinking of buying it, because I find myself often having to blow dust off things and I need more power than what my feeble lungs can provide.

I can't figure out if it has a bottle in it or if the compressor outputs the air directly... if it doesn't have a bottle it sucks.
I'll post when (and if) I get it.

Here's one for $69.99 with a 2gal. tank. Northern tool also has less expensive ones.

Well someone I know is in the air con business and they have a scuba tank of air to flush out some of the systems.

The place he get's it filled doesn't like aluminium tanks as someone had one and it exploded and blew a massive hole in the side of a shed, there are other stories too but I haven't heard them.

If you're spending that much on compressed air, it would make sense to get a small compressor. Might as well put together a small spray rig... that way it would be useful for other purposes, not just cleaning. You'd have it around if you ever wanted to get into speaker finishing, furniture refinishing, painting, etc. You could get a small rig for the cost of a few cans of compressed air.

How hard will that $100 craftsman and $70 coleman blow air compared to the cans of compressed air you buy? And how loud are they?
