I have an old fan with 3 inch duct. This unit has the same dimensions so I like the size, but will a 4 inch to 3 inch reducer work &amp; connect directly

My husband did the installation and he did need an reducer/adapter. He can't recall the size, but the guy at hardware store was able to find the correct one as he took new one with him. Seem like the smaller one is the standard size, as we have answered this question from other customers. Good Luck! We like ours, nice and quiet.

The connection on top of the sander works with a 4" ID hose so a 4" ID fitting should work. Try Rockler 4" To 2-1/2" Reducer Item #: 89195. Check the Tech Specs to see if it gets you where you need to be. I have mine hooked to a 4" hose.

It is greater, probably closer to 5 or 6 inches. I don't think there is any way to reduce the size-not likely to find an adapter that will attach well. It is very similar to a dryer vent tube.

It would be very difficult because this fan is over 8" diameter. Why would you want to use such a large fan in a small duct? If you are determined, I'm sure you could make an adapter to custom fit it in line, however, a computer fan might be more compatible in this application.

No. It moves a lot of air and it would be restrictive to go to a 4 inch duct.

To be sure go buy a one inch male pipe thread coupling. It has the male on both ends looks tapered (large in middle gets smaller on the tips) hold it up to the one going into yours. 3/4 and 1" are pretty different look at both at the store maybe even get both you can return them. You will know right away.

I don't believe it will, my duct is exactly 8 × 10 and fits perfectly. I'm assuming any other smaller/larger duct wouldn't work.

Probably not, the motor/blower housing is much larger in diameter than the normal 4" dryer vent piping. It is more than a stud width in diameter and has fittings on the exterior for the pressure switch and electric connection cable. The unit needs to be mounted equidistant between the dryer exit and the vent exit to boost the exiting air properly.

It comes with flexible 6 in duct. You would need 8 in to 6 in duct reducer.

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. no big deal... but you may need reducers depending on the size of pipe coming from well. and you may need adapters at the entrance and exit of the filter housing, but in any case you're looking at a few dollars at most. The best way to approach it is to see what size comes from well, what size and type (slip or screw type) you want going into the filter housing and get what you need to make the match.

I ordered this as a replacement for the original fan that wore out. My recommendation is to take a good look at your current fan. If the screws line up the same, it should work. I have a 4" fan housing and it fit great with one exception- I had to remove the flaps on the inside of the vent to make it fit. Overall I'm very happy with the results. The fan is much better than the original. I hope this helps! PJ

You can, but you'll need a reducer from 4" to the 2 1/2". It won't reduce your cfm's.

This cap does work with 3" duct. It comes with a reducer to go from the 4" cap to 3" duct. You will still need a hole in the wall to fit the 4" cap into.

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.

Its not a reducer, its a raw receiver tube you weld onto something. Your reducer wont have the collar on the end.

The part that you put into the duct is 9 and 3/4 inch x 3 and 3/4 inch with 1 inch height so it will fit the standard opening of 10x4 inch OK.
