Works great. Cost me That's the cost of 3 cans of air plus tax. Message 5 of Message 6 of Have to make sure the air out of the compressor is dry. Message 7 of I'm leary of using forced ait to clean. What if I prefer the vacuum method. Just have to careful not to slam it around inside your case. Message 8 of If you ever seen the A-plus testing or study guides, it is recommended that compressed air is used over a vacuum cleaner because, as they put it, a vacuum cleaner can cause a static charge to build up.
A-plus also calls the connector on a hard drive a "Berg connector". Message 9 of Take a look at the contents of a can of common gas duster, like Dust Off. While not an ozone-depleting gas, difluoroethane is a greenhouse gas. It has a Global Warming Potential GWP of , according to the EPA , meaning one pound of difluoroethane is the equivalent of pounds of carbon dioxide when it comes to global warming.
Cans containing tetrafluoroethane are far worse, with a GWP of 1,, and lasting 14 years in the environment. Canned air works through a useful, and honestly fascinating quirk of thermodynamics, explained in a quick video by Minute Physics.
The liquids will rapidly cool anything they land on. If it touches your skin, you can get frostbite. The can itself very rapidly cools, such that you can receive cold burns on your hand from holding it too long. Some gas used in canned air is highly flammable.
Just get an air compressor. No worries about the liquid coming of the can, and much more air pressure to get that stubborn dust out. May 16, 0 0. Liquid coming out is part of the fun, though.
