Vortex air cooling

[silent tone]

Check this out

They sell cooling units for shop machinery. Apparently these devices can generate cool(dry) and hot air streams from compressed air with no moving parts. One statement says 100F below compressed air temp. So, all we need is a cheap way to get compressed air, right? Any ideas?
