I noticed that your processing 5 gallon batches. Why did you settle on that sized batch tank?
I noticed you're using a rather high volume fan. Do I need that much air flow?

1] 5 gallon batches for two reasons:
a] space. I have very little spare room in my garage.
b] I collect the WVO in 5 gallon jugs. I can pour it straight into the processor right after collection. No dirty oil sitting around.
2] High volume fan:
It's not really high volume. No specific calculation done there. It's the only small blower I could find which runs on 120 volt AC.
You need enough air to carry away the moisture when heated to 150f or greater.
The fan does have a cooling effect because the air passes over the oil stream as it falls back to the tank.
You will find it necessary to keep the heater(s) on when the fan is running or your batch will cool down.
