Current sensing (for slightly low current, fans spinning air take less power
than ones moving air) is one way but is likely to be more expensive than a
vane on a switch to watch for no air flow on the exhaust.
Another possibility is to look for a lower pressure (higher vacuum) just
ahead of the main unit.
