Re: Vacuum Cleaners from Outer Space

I dunno if this is the current fashion in the military, but I usually
use compressed air to blow the dust out of dangerous hardware. A
vacuum cleaner can generate a pressure differential over only small
area. If you have to get the junk out from under components, a
vacuum cleaner just doesn't work. However, an air gun with 100psi
behind it will remove the dust and probably some of the paint. If
area contamination is a problem, I use a funnel made out of a plastic
bag (or cardboard box) which is attached to a vacuum cleaner. When
the air gun causes the dust to go airborne, the vacuum cleaner easily
catches it in the air. That's the way I do computahs and server
farms.

Oh yeah... wear a respirator.

And make sure that you have the right kind of air supply.
The three common types are:

[1] Clean dry air.

[3] Clean dry air that has a fine oil mist added to lubricate
pneumatic power tools.

[3] "We don't care if huge drops of dirty greasy water condense
out of the [ air + water vapor + oil + dust ] stream" air.

The easy way to do a quick test of this is to blow tha air
through clean white cotton for 30 seconds or so.
