With APM one can construct devices which act as pumps and fans that seem to have no moving parts and are only acustically perceivable when something is hold into the (laminar) airstream.
Including arrays of micro sized fans into a flexible metamaterial is called a fancloth (a concept by by J. Storrs Hall). Its a bit like an active sail. Also from J. Storrs Hall is the concept of wheels turning on the surfaces or moving surfaces to reduce aerodynamic drag to the negative regieme. High speeds need either infinitesimal bearings or special levitated bearings that can deal with the pressure. Things get interesting when the speed of sound gets approached. Its like a nano-turbomolecular-pump running at ambient air pressure (but with pre accelerated molecules).
Air accelerators: One possibility may be to capture air or liquid bubbles at the entrance completely (not partially like mentioned before) of the material use capsule transport to move and maybe accelera this batch and release it at the outlet side. When dealing with gasses one must take care to avoid to unintentional build a heat pump
