Perhaps the OP meant "500 cfm."

Still wondering how to push 5000 cfm through a 14" duct (at 54 mph :-)

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.

Installed perhaps but a 5000 cfm window mount can be purchased for slightly
over $300 from SAMS.

Perhaps you are thinking about a 5000 Btu/h window AC. Grainger sells
a 7F889 blower that will do 5000 cfm for $1324 in a box, vs installed.
It has a 20" wheel and a 1 HP motor and weighs 240 pounds and measures
38"x37"x33", with a 25"x25" air outlet...
