Perhaps the OP meant "500 cfm."

no. evap requires much more air movement than central a/c. 5000 was probably
on the low side.

He said he paid $550 for the unit. Bare 5000 cfm blowers cost over $1000.

Evaporative cooling can be very efficient with small airflows
in a well-insulated airtight house in a dry climate.
