Long Dryer Run Venting

[fnelson487]

Well, since I finally got the 906s installed upstairs, I moved the Neptunes to the basement. They have been growling at me ever since. I never did have a true dryer vent setup down there. The 806s that were down there were hooked up to a internal vent since it was electric and my contractor never could figure out how to set up a vent line.

My basement ceiling is filled with HVAC ducting with very litte room for a vent line. The exterior walls are solid brick so he wouldn't even attempt it (chicken.) I really wanted to do a proper venting since the Neptune dryer was gas. I had a 4" vent line running in the ceiling from a bathroom on the other side of the wall from the Neptunes all the way through the basement ceiling and through the brick wall. If I could figure out how to use that line, it would make my life much easier.

The problem was that that vent line was over 35' long. I had this issue in California with a dryer in the middle of the house which sat on a concrete slab. It never was satisfactory. I knew that a long dryer vent line presented problems and did a bit of research (I think I heard about the solution here.) The solution, of course, was a dryer vent booster fan. See below to the link to Fantech. It has a pressure switch that activates the fan when it senses air movement in the vent. Here is a shot of the final installation along with a link to Fantech.

Here is shot of one of the runs

5 feet along the wall behind the dryer, up 8 feet, across the ceiling above the HVAC venting.

Next to the booster

They recommend at least 15 feet between the dryer and the booster fan to reduce lint build-up. It is about 18 feet for me.

Across and Down

Then about 12 feet in rigid pipe. Finally through the ceiling in the vacuum room and a bend out the wall. I have run the electrical hook up and will do the final install tomorrow. Whew!

That is very interesting Fred thanks for sharing all the great pictures. My this was really a process wasn't it? Terry

For years I recommended Fantech on THS.
For some reasons most home venting limits shorter duct line and this completes the bridge when it is way too long for proper ventilation!

Thanks for sharing and helping others reach there goals!

Great job Fred, I can't wait to see - and hear it running!

looking good-- can't wait to see more!

We need that.

Where can I find such a thing? And about how much will they run? We have a very long run for our dryer vent, and it is affecting the dryer's performance.

Agreed on the long dryer run but....

My Maytag Neptune compensates for it and does just fine. I am thinking of reconfiguring my laundry room so that the dryer venting will be at a minimal. Maybe adding a top-loader along with my original Neptune.
