Which compressed air can to use to clean Internal of PC?

you do NOT want compressed air.

Compressed air would be just that - compressed air. It would be what? mostly nitrogen, with water and dust and all kinds of bad stuff you don't want in your PC!

Dust-off is a compressed gas, usually difluoroethane.

It does evaporate instantly, and completely.

It is the correct choice - yes it is flammable and causes brain damage when inhaled - because it ISN'T compressed air.

It isn't the type of canned air you use but how you use it. Any can will do, I always go for the cheapest.

Here's a guide on how to do it correctly

This is so wrong I don't even know where to start first.

You do realize the atmosphere is 70% nitrogen right? If it were dangerous in compressed air it would be dangerous just sitting around. Nitrogen is an inert gas used for all sorts of other things when you don't want chemical reactions.

You only get water out of a compressor with a really shitty setup. Any decent compressor will have a drier on it to get rid of moisture. And if you're using compressed air your cooling the parts anyway, which could cause condensation. In any event as long as you let it dry for a minute you're fine.

Finally compressed air doesn't have huge amounts of dust in it, that would wreck the compressor, they have filters for a reason. If somehow it did have dust it would be a lot less than what you're blowing out of the PC anyway.

Air compressors are not all created equal. I have an old central pneumatic that that blows out a nice bit of oil and water every time you use it. Is that harmful? well... I wouldn't want you to blast me with oily water in an attempt to clean me, i'm sure the PC feels the same way.

Dust in the compressor is a guarantee, how many microns do you think that filter cleans out? Now its not like the air compressor is a rail gun - you're not launching the dust at speeds near the speed of light - so chance of damage is almost zero - but there is a CHANCE.

Now the ingersol rad in the shop has a nice set up and drains its condensate nicely. Nitrogen is certainly harmless, as well as all the other stuff - but if you blow oily water into your case - even a little bit - it is going to be there forever. The water may evaporate but the oil won't and neither will the suspended solids in the water that will remain after it evaporates.

Tl;Dr

Get a can of compressed air from a dollar store.

*Gas it isn't air, if you breathe it you could die.

You know what im saying.

Who buys a can of gas with the intention of using it anywhere near their mouth?

Central Pneumatics are crap, I had one for a month, then another one for a month, the chewed through piston walls like nothing I've ever seen. Then I bought a real compressor. In any case a decent compressor should have a post filter that removes oil and water. I wouldn't even use air tools on a setup that's missing the filter. If the compressor is spitting out tons of oil I would get it checked, there's probably something wrong with it.

And like I said the technique is the most important thing. Even if you use the purest air to clean the case, you can get dust particles from inside the PC shooting around at the speed of sound, and if you're doing really bad things you can destroy fans and other components in the process, regardless of the source of air.

Fire fighters, confined space rescue, hazmat responders, tons of people. That's what cans of compressed air are for.
Language is the only thing we have to communicate, using correct terminology is key, even if it seems obvious.

sure i could have worded it better but im sure you knew what i was talking about, in this context is should be fairly obvious what i meant to say.

So the answer is what exactly? people arguing and the end result isn't clear.
What is the core stuff to look for, is even the cheapest one good enough for major dust cleaning?

It never is specified about compressed air in cleaning tutorials, ever tutorial ever(or as far as I have seen) just states "you need compressed air and...", as if it doesn't really matter at the end what kind of you use.

I am not amateur, I just want to know about these cans of compressed air, since I was looking at my local internet shop and I saw these prices, the other difference was the capacity/volume, some were cheaper in price but has more capacity, while others are bit more expensive, the same question basically like about HDMI and RJ45 cables, where it has been already answered, that there is no difference whatsoever in these cables, except HDMI with gold plating for better conductivity, but that's just like nitpicking stuff and you are good either way, so even cheapest HDMI cable will do fine from a decent electronics shop, same with RJ45, both have cons within the length, as in with every other cable ever which looses performance as it goes over certain length.

But is it actually the same with compressed air cans sold at electronics shop that obviously is meant for electronic related stuff and not the ones like you would find in a car shop that has specifically a different chemical compound for added effects and other reasons? imo it is really confused since I just want to clean my PC out of dust from internal components and that's it. So is there a sane person who can answer in a simple language without going into chemists field so detailed that at the end will just either make you more conflicted or just will make you so dumb that you will just buy the expensive one just because some dork said it on forum with this chemical table of explanations?

Sometimes it really amazes me how on a simple question about simple thing within a specific field of expertise page (computer/electronic tech and its related stuff) no one can really answer in short terms in understandable language.


Why should I give a damn about it so much, that I should stay away from cheap stuff? I am saying cheap stuff since usually cheap stuff is the badly manufactured with minimum care placed on it...but c'mon, it's just a pressurized air/gas inside, so what can go wrong anyway?
Why no tutorial ever mentions any specifics about compressed air and their compounds of choosing like it does with HDMI or RJ45 cables?



Here is something from wikipedia...and it just bolsters my argument about compressed air instead of compressed gas...can you guys argue against these claims?
"Compressed air is air kept under a pressure that is greater than atmospheric pressure."

"Compressed air is used as a breathing gas by underwater divers. It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres."

"Air for breathing may be stored at high pressure and gradually released when needed, as in scuba diving. Air for breathing must be free of oil and other contaminants; carbon monoxide, for example, in trace amounts that might not be dangerous at normal atmospheric pressure may have deadly effects when breathing pressurized air. Air compressors and supply systems intended for breathing air are not generally also used for pneumatic tools or other purposes."

"True liquid air is not practical, as it cannot be stored in metal spray cans due to extreme pressure and temperature requirements. Common duster gases..."(that's the name of the cans - Gas duster - that we use for cleaning) "...1,1-difluoroethane, 1,1,1-trifluoroethane, or 1,1,1,2-tetrafluoroethane. Hydrocarbons, like butane, were often used in the past, but their flammable nature forced manufacturers to use fluorocarbons.
When inhaled, gas duster fumes may produce psychoactive effects and may be harmful to health."

"Canned air can be used for cleaning dust off surfaces such as keyboards, as well as sensitive electronics in which moisture is not desired. When using canned air, it is recommended to not hold the can upside down, as this can result in spraying liquid on to the surface. The liquid when released from the can, boils at a very low temperature, rapidly cooling any surface it touches."

"True "air dusters" using ordinary air are also available in the market. These typically have much shorter run times than a chemical duster, but are readily refillable. Both hand pump and electric compressor models have been marketed."

" Recently electronic versions which only use air have become viable alternatives that are preferred by many large corporations due to the fact that they contain no hazardous chemicals, are safe for the environment, do not freeze and they cannot be abused by addicts looking to get high. The leading plug-in alternatives are made by DataVac and Airrow and the leading cordless alternative is made by Canless Air System."

So I suppose that there are true compressed air cans/aerosols out there without this gas bs problems in order to figure out "The Best Aerosol For Cleaning Regular Components, just for 99.99$, It's Just The Best! A Good Reason For High Price. Oh And It Has LED Display, So That You Can See How Much You Have Left, AAND RGB color!! But It's Just Regular Air/Gas Inside!!, We Simply Want To Make You Confused About Simple Things!!"
