[VAC] fantastic fan current draw

[jon fitz <fitzjo1@xxxxxxxxx>]

After a particularly warm weekend I have been
instructed by the boss to install a better ventilation
fan.  I have seen a lot of postings about the
Fantastic fan.  Obviously, this is a popular unit. 
But, I almost always boondock.  So, I am concerned
about the current used by the fan.

Does anyone know how much current their fantastic fan
draws?  Or, can anyone relate their experience using
one while boondocking with a single deep-cycle
battery?
