Air-driven equipment cooling fan?

There must be more efficient ways to generate an air stream from compressed air than running a fan.

Nobody is going to bother to do this. Just use the air, with a venturi, to generate the required volume. More efficient than having an air motor, and then a fan, both with losses. Look at:

Who are specialists in designing air powered cooling, ranging from venturi systems, through vortex systems (allow cooling below the ambient air temperature), right up to pumped heat exchangers.

Have a look at this site....

it may be a better solution. By using this device you are feeding what could be filtered/de-watered air into the enclosure with pressurisation of the enclosure to eliminate ingress of dust/contaminants, etc.

Google "compressed air venturi mover" and "compressed air venturi conveyor" and see what you can find. Here is a link to one unit...

and more.....

If you direct direct a 1/8" nozzle down a 6" tube you will create air flow through the tube at a n air volume significantly higher then the volume out of the nozzle. Air motors are going to be noisy and require maintenance, an air nozzle can be designed to make very little noise and maintenance is VERY minimal.

Hope you find some use from the above.

Try a Vortex cooler. Vortec or Exair.
