12V 16" DC venturi fan

David;
 If not available, stop by your local auto wrecking yard and ask to look for an electric radiator fan. Most newer cars no longer use a pulley fans and a pair of 12 volt radiator fans will probably help you out in a pinch.

Hey guys,

I checked on availability and they are back-ordered for a month. 

Regarding the junkyard fan idea:
that should work fine if you are using 12v battery.  If you intend on going pv direct, however, the motor will not likely appreciate the 16-18 vdc that a solar panel would supply.  It may tolerate it, but I suspect it may have a narrower voltage window since it was designed to be powered by a battery.

just an fyi, this item is not like a solar attic fan.  It is just a dc fan.  we also sell a kit with the dc fan and the pv panel.  the solar attic fan is different and you can get that from us as well as other retailers.  There are several brands, but we carry natural light, who were just featured in home power magazine #112.

feel free to contact me with any questions.
