I have read instructions on how to clean the internal parts of my computer, and they all say to use canned compressed air. I have an air tank that I use to air up tires, blow the dust out of filters, etc. Could I use this tank of air, or could I use the blower feature on my vacuum cleaner?

The air in that tank would probably contain some oils. Maybe not very much but it would have something like that in it.

If you have a small vacuum, like a Shark, you can use those but be careful of any brushes on the attachments as they may generate static. The crevice tool is handy.

The canned air is good but I hate having to pay for air. :thumbsup:

I have a shop vac, and it has a place where you can put the hose so that it blows air instead of sucking. Could I use that? I hate to pay for air too.

Canned air is the best, most companies use an inert gas so that there is no chance of creating static electricity.

As rigacci has pointed out the air in the tank can contain oil, most compressed air has a by product of water, most compressors used in sensitive areas will use a dry filter.

There are small vacuum cleaners that are built specifically for the use of cleaning computer cases, I haven't seen one up close and personal yet to see how they address the static electricity problem, I suspect that a low volume of vacuum is one answer. If you are careful you can use a vacuum, just make sure that you don't touch the nozzle to anything inside the case. The problem with vacuum cleaners is that the large amount of air and dust particle traveling through the tube is a great static electricity generator.

You can use the shop vacuum to blow out the case, but I doubt that you will get enough volume to be able to blow out the heat sink and fan on the CPU.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

If it's a piston-type compressor, I wouldn't use it. I have a small oil less compressor (diaphragm). You still need a regulator to reduce the pressure. Just cracking the valve is not enough. I know a person that uses a bicycle pump


Or you could do what Dachew does and use a gas-powered leaf blower :thumbsup:
