Question about Fantech Fans Exhaust Fan In-Line
I replaced an existing bathroom exhaust fan with a higher powered model. After showering in the bathroom, the exhaust vent is quite wet and actually drips water. I am using 3 feet of flexible tubing from the fan that attaches to non-flex sheet metal duct pipe, exiting straight up to the roof (about 12 feet). How do I reduce/stop the moisture in and around the vent? The temperature outdoors and in the attic is currently about 20 degrees.
Another solution would be to have the exhsut fan discharge firts into a metal duct tilted at an angle so that the condensation runs away to the end of such duct.This tilted duct has a spigot on top from where the insulated flexible duct transports the air to the vertical metal exhaust duct.
The condensate water collected at the end of the duct will evaporate eventually.

I work for Fantech and your problem is you must keep the fan running after you shower to exhaust the humidity...I would recommend at lease 20 minutes.

The fan is pulling too many cfm (cubic feet per minute).you can replace the switch of the fan with a potentiometer type switch (this works like a light dimmer)you can reduce the speed of the fan,or you can use a couple of synthetic fiber filters to trap the condensation.good luck
