What is the best way to clean dust from a large number of computers?

Question

Service maintenance

Hello! At a not the smallest enterprise, I was given the task of servicing 40+ machines. At the moment, a catastrophic amount of dust has accumulated in them. In a week, intense heat is expected and overheating of equipment would be very undesirable.
Can you please tell me what is the most efficient way to serve such a number of computers?
If using a vacuum cleaner, which one? We need concrete examples. Interested primarily in the lower price segment.

Answer 1

Compressors are not very good at cleaning computers as well as powerful vacuum cleaners due to the fact that they can suck out / blow away some parts. Yes, and their efficiency is low, because the dust shrinks a lot and even powerful vacuum cleaners cannot suck it in.
It will be effective as follows: You will
need: the cheapest vacuum cleaner (1000r) + brush for painting (20r) + old toothbrush (free) + Phillips screwdriver (50r) + eraser (10r)
Take a brush for painting, brush off the dust with it and vacuum it at the same time so as not to fall apart. With a toothbrush, you clean hard-to-reach places, then the separated dust is easily sucked up by the vacuum cleaner. Eraser you clean the contacts of the RAM and vidyuhi. It is highly desirable to disassemble the power supply and clean it too, after discharging the capacitors (not much, but I can shock).
Cleaning one computer with disassembling the power supply takes me a maximum of 15 minutes, without a PSU 5-10 minutes. In principle, 40 computers can be completely cleaned in 10 hours of unhurried work.

Answer 2

At my last workplace, I knocked out such a thing for myself - a vacuum cleaner for PT-1100 toner www.catun.ru/pt1100.html
For lack of a compressor and the ability to use it, I was happy as an elephant :)
But yes, the brush was also used in hard-to-reach places.

Answer 3

Agree with previous answers, compressor is the best solution. I myself work at a factory, where there is always access to pipelines under pressure, so I always blow the computers there, though the air is not always dried (there have been no unpleasant precedents yet).
There was a special vacuum cleaner, of little use, it does not always clean, you have to brush off the dust with a brush.
