Can I install 4 inch duct directly to BOTH ends? It looks like the inlet and outlet are different sizes?

Both sides are the same. Standard dryer venting from the hardware store fits just perfect.

No it doesn't. But a 4" flex duct fits on with a little bit of work and i think you could buy an adapter at home depot, amazon, or lowes. I bought this for my mother in law bathroom and it is so quiet. Easy to install. I put mine in a wall above the toilet next to the shower.

I would think that you can buy a large dia duct of the right length to extend the exhaust end of the stock unit. But I don't recall any instructions in the package that addresses that possibility. I only had to penetrate the 4 inch stud wall to the outside of the bathroom.

I am not sure if this is a mounting measurement or the intake side. I would recommend getting one that is the same as you have.

Not certain this item is good for your application. Try to see if Fantech has a fan that has a three inch opening. Also, measure your vent length to determine if this model is the right one for your application. Finally, you may be able to change the vent size. If not there is an adapter piece that fits onto the three inch vent to adapt the opening to accept a four inch vent pipe. Obviously you have several choices ahead of you, good luck.

The ouptut duct for this model is 4" in diameter. If you are replacing an existing exhaust fan, you will probably have a 3" plastic flex duct vented directly into your attic which is not code compliant. Correct way is to replace the 3" plastic duct with a 4" insulated duct and vent to the outside directly.If you use the existing 3" duct, you will have to purchase a 4" to 3" adaptor.Hope this helps.AMGContracting

You can as I did. I had a wall which is wider than the included sleeve so I went to my local big box hardware store and picked up a standard duct piece and used it - its been working fine for the last year. Use metal duct tape to attach it. I believe its and 8" or 12" duct - easily found or fabricated. Good luck!

I don't believe they're designed to connect to each other. If you cut the end off so you have a round opening, you should be able to get 4" round flexible drain pipe that will fit into it.

The inlet and outlet are 1/2" NPT male, US pipe thread. You would need an adapter to connect a hose coupling.

My installation took 12" of pipe. I dont think you could install with less.

Not exactly. The hole on the fan is 6". With that said I put a new 6" duct from the fan to the hole in the roof. The hole in the roof is a 4" hole. I just put a 6" to 4" transition and the fan runs fine. It is super quiet and gets plenty of flow.

WE purchased a 6" piece of duct in the heating department at homedepot, we also picked up a reducer from 6" to 4" which allowed us to use the venting for a dryder. But we had a good 12feet until the outside of the house, so we only attached the 4" at the end 2 feet. Now for me the opening on this unit was a little under 6" so I had to use tech screws to attach it along with some duct tape. If you use a reducer - Do Not use it right at the beginning. The fan will sound obnoxiously loud and you will be unhappy, trust me. Reduce as close to the outside only if you have to. This exhaust was used for a basement and I needed a side vent.

Not sure about your questions but here are some numbers that might help you. The tip is about 4" diameter circle on the outlet side and 3" on the inlet, that's outside dimensions. It's 9" long on the top and 8" long on the bottom since it's slanted down. And make sure you exhaust pipe is 1-3/4" diameter or bigger otherwise you won't be able to clamp it on without modification.

It is smaller on the intake side which will take a crimped 4" duct connection than the exhaust side which should slip over an uncrimped duct

yes 21/2" on inlet and outlet. it made my gsr swapped civic sound a little quieter with less drone/rasp. When I redue my exhaust to a 3" I might use 2 of them. the only downside is they're heavy

No, this is only for install directly through a wall. They do have other fans for 4 inch duct...
