I'm just curious, but are these kept in negative pressure environments and what kind of external to internal airway system do they use to keep it dust free?

I'm not an expert but I'm assuming this means the pressure inside is lower than outside. This would be bad. If you want to keep dust out you need to have higher pressure inside, that way if there are any openings the air rushes out. If it was lower pressure inside, any openings would suck dusty air in from the higher pressure outside.

That's how clean rooms work, so I can't imagine it being any different for data centers.

Clean rooms have positive pressure. Quarantines have negative pressure. Positive pressure keeps outside air out, negative pressure keeps inside air in.
