condensation on intake fan, a problem?

[linky]

Since its winter I decided to pull nice cold winter air from outside (through about 12' of 6" ducting) to give my mini split a 6 month or so break and save a few bucks on electric. I am using a can fan 600, out that through another 6' or so of ducting through a hepa filter into room. I am controlling it with a temperature control thermostat. The problem is the ducting and the fan get very wet from condensation. I don't mind the wet ducting but I am not sure if this is safe for the inline fan. Anyone know for sure if this is safe or not?

thanks all

Since its only on the outer casing I don't see a problem unless the electrical connections are exposed to water.

You could insulate with a duct sleeve.

Insulate the ducting or the fan itself? I was wondering if its just on the outside that is getting wet or if the electrical components on the inside are also getting soaked.

Insulate both. U can cobble together a blanket for the blower using some duct sleeve insulation. Only part getting condensation is the parts in contact with the warm air.

yes insulate the duct, but make sure you wrap it tightly around the duct ,and I would also pitch the duct on a slight angle back towards the outside from where you are pulling the fresh air in , this way any condensation build up on the inside of the duct drains back out away from the fan
