Tell us about yourself!
the fan is inside the plastic "room"( if you look close you can see the base of it in the pic) basically it just circulates the air inside the kiln, the plastic tube directs the damp air towards the dehumidifier without blowing over the lumber again. Be warned home dehumidifier are not designed for wood drying. The coils will slowly deteriorate from the acid in the wood. Coils in wood kilns are coated for protection. Coated with what?....I have yet to find out.
