Well, I can't find any info on your particular converter but a filtered power supply probably only refers to a consistent regulated source. Is there a dedicated charging circuit which may be higher voltage and less regulated to avoid?
I have installed several of that particular model of Fantastic fan, wired in various ways, and have experienced nothing but consistent quiet operation. In fact the fan runs great when wired directly to the battery
with the battery
wired to a charger. Even in this configuration, the fan worked perfectly when hooked to shore power and also when boondocking
, all the way through the range of voltage drop overnight.
Maybe someone else may have an answer, I don't even recall the that particular recommendation or any problems associated with it.
