From the looks of it, it's a two chambered pump that uses pneumatic
"amplification" (similar to hydraulic advantage).
For example: two pistons, connected by a common rod. Piston one is 2"sq and
takes 60psi--that's 120pounds applied to the other piston, which is only 1"sq,
producing a 120psi output (but one-half the volume of air). There's valving
that allows the piston to cycle, so the output would be pulsed, but at a higher
pressure determined by the relative sizes of the two pistons (and the input
pressure).
There's a similar type of device used to inflate the struts on aircraft landing
gear, which can take upwards of 400psi. The input can be 'normal' compressor
output; i.e. 80-120psi or so.
