How can I purge the computer from dust (except for a spray can)?

Question

Computers

Hello!
The old Vityaz vacuum cleaner, which had a blow-purge function, died.
Samsung's home vacuum cleaners don't have this feature.
The cans run out quickly. Yes, and the quality of blowing is so-so.
What other options are there? In addition to a trip to a car service.
(I tried with a hair dryer, it blows very weakly)

Answer 1

The tool for this is called a blower.
For example, Hitachi RB40sa https://www.vseinstrumenti.ru/sadovaya-tehnika/voz...
Or similar ones, Makita is cheaper, but no worse.
It blows everything out, it can knock out memory sticks, tear off fan blades, and fingers along with them, if you hold it nearby ... In short, you need to keep a reasonable distance from the iron, or do a little less speed (if there is a regulator).
It does not help much if the computer was in the garage, and the oil dust is inside, or just very fine wet if it gets stuffed - you have to help it a little with a brush, then it will blow away.
DO NOT clean laptops like this! Just disassemble, separate the fan from the radiator, and with a brush.

Answer 2

Compressor

Answer 3

You can use a compressor, but you apparently don’t have one))
It’s quite a normal option - to take a brush and sweep away the dust with it, or with a pepedaster.

Answer 4

Car pump! It can also be foot, but electric is better.

Answer 6

Go to a flea market and buy a second vacuum cleaner with a purge function.
If you're lucky, you can for 500-1000r. some kind of "breeze" to take.
