Air supply may be delivered via any compressed air source, and filter either pre-ventilator or post-ventilator. I imagine that, in a pinch, portable air compressors (the kind that run air tools) could be used, perhaps in a bank of multiple compressors to provide redundancy / overcome duty cycle limitations. I read somewhere that 50PSI was required for inspiration, which sounds high to me, but regardless this concept should be able to be used for any pressure given the right materials.
Now that I've said all that, someone please tell me where I'm wrong.
