If there was an thread on this already I over looked it.

Calling all Earthship Dwellers, Earthship Builders, Off-Grid Folks and others in the know. I am trying to spec out exhaust fans for the bathroom and exhaust hood for the kitchen for our Earthship here in the "Land of Ahhs".. How did you accomplish this task? I am looking for 24vdc exhaust fans for this purpose but the search is not getting me far. All responses much appreciated.

The automotive industry has pretty much perfected the art of moving air with DC electricity... Blowers are plentiful and inexpensive. Problem is, they are based on 12 volt applications. I suppose you could install a '24 volt to 12 volt DC/DC converter' between the 24V source and the automotive blower motor. I'd think you'd want to do that anyway to take advantage of all the clever gadgets that are built for the RV, automotive, and trucking markets. Also check out 'bilge air blowers' designed for boats.

Trucks, buses, old landcruisers and Nissan patrols run 24V electricals. Put "24V fan" into ebay. If you really want some airflow put "24V radiator fan" as your search term. Bear in mind radiator fans are for intermittent use, not continuous use. Joseph is right auto industry is great source for DC powered stuff. Ebay is your friend or you can even try the local breakers yard for some real cheap options.
