Instead of a pneumatic cleaner in a cylinder, what else can be used?

Question

Iron

Good afternoon!
From time to time, several dozen laptops, system units, etc. need to be cleaned of dust. Since this year, I tried to use a pneumatic cleaner in a cylinder for 200-300 rubles. The bottle only lasts a few times. And the main problem is the used cylinders, you need to get rid of them. Therefore, I want to ask you: is there any alternative to this cylinder?, for example, some compressors specially designed for cleaning computers, etc.
Thank you.

Answer 1

An ordinary compressor with a receiver and a gearbox at the outlet, capable of pumping at least 8-10 atm and a receiver capacity from a liter and up to how much money is not a pity.

Answer 2

Self-refueling of cylinders is of course not an option.
Nothing like a factory cleaning bottle will work, at a factory pressure of 50 atmospheres, this is 10 times more than you can get with a household compressor.
In practice, electric blowers are used for mass maintenance of computer equipment.
Cleans certainly not perfect but enough for regular maintenance.

I saw a funny system.
Server room, there are several racks in it, once a month a special person in a mask comes and blows one rack with servers, of course, all the dust takes off and ... is distributed to neighboring cabinets, because. there is no air exchange.
But every month a stable cloud of dust is blown out of the server, it’s not in vain that a person receives a salary.
