Does the reverse hold true for compressed air?

Not really, at least not under any conditions you would normally encounter.
Given a suitable pump you can raise the gas pressure feeding a line to hundreds of atmospheres above ambient, but you can only ever lower the pressure to zero, like temperature the scale has a lower limit, and it becomes exponentially harder to lower things as you approach that limit....
Incidentally, just saw a smallish side channel blower for £60 buy it now in the UK on ebay.
