Refillable canned air

[pendragon1998]

I need a can of air to blow off photos before I scan them and to dust my computer case. It hit me that I have an air compressor already, so who makes a good refillable aerosol style can I can fill at my compressor? Since I am spraying air on sensitive electronics and photographs, whatever is needs to supply clean air with no oil or water in it.

You can drill out the bottom of an empty can and thread on a valve to fill up

there are videos on youtube on how to do this.

"Canned air" is shipped as a liquid. You get a large volume of constant pressure gas as it boils. Using regular compressed air in a can would result in a few second of a strong blast, and then several seconds of uselessly weak puffs. You pretty much need the big tank and a real regulator to make a usable substitute.

Couldn't have said it better myself...

So? That just means you'll be refilling it more often, but it will still work.

I've got something like this. Basically an aerosol can duster with a schrader valve in the bottom. Yeah, it only lasts a quarter a long as a can of "canned air", but it doesn't spray liquid when inverted, and it's nearly free to refill.

But for your purposes, why not use the compressor directly. Get a safety tip blower, regulate the air output to 30psi or so, and put a filter inline with the blower.

Northern Tools has the refillable cans for air or paint and stuff.

They already sell cans of compressed air for this exact purpose.

But i'm sure he doesn't want to have to keep buying them if he uses them frequently. I hate the idea of using a can of air and having to go buy another. I'm thankful i don't have to pay to use the air on this planet, yet... i'm sure it will be taxed at some point.

Suggest running an air line after a dedicated regulator (it might be just 1/4 id poly) from the compressor to your work area. Add a filter that uses a toilet paper roll element to filter the air. Will last forever and lower cost than the air can.

Harbor Freight. Just cut off the air chuck and replace it with a blow nozzle.

I use the small, portable tank with CO2. Is just great when you need compressed gas and don't want to haul a big cylinder or air hose around.

This, you don't want to clean electronics with general shop air. Oil, moisture and all that are not good to blow on circuit boards.

To blow dust off photos or computer why don't you used a hair dryer on cold setting?
