Defrost blower?

Can someone suggest a low-current, light-weight, inexpensive 12 volt fan to
use in the defrost branch of the cabin heat line for clearing up a
windscreen while still on the ground, when ram air from the prop may not
amount to much? thanks

Scrounge through some dead computers. Some of the muffin fans are about the
size of a scat tube, and put out a substantial amount of wind. They also
happen to be 12 volt DC.

Many hair driers have 12 volt dc blowers in them. I used a pair of
them in my electrified Fiat 128 for defrosters. Used another one for a
motor cooling fan.

When I scrapped the fiat I saved one of them and used it for blowing
up an air-bed for camping.

Or try your local car wreckers. The heater fans are quite powerfull in many
models and run quite happily on 12 volts with hot air as well.

Hope this helps,

They're also quite heavy and way over powered for this application. A small
computer fan would do the job nicely for way less weight and electrical
load.

Not to mention the fans are virtually ALL built into the heater
assembly, and being squirel cages, are useless outside the case.
