Is there a way that this could work on 4 inch duct to the outside?
824983
No, this is only for install directly through a wall. They do have other fans for 4 inch duct...
824984
I would say no. This fan mounts in the wall. It fits through the thickness of the wall and vents directly to outside, using no duct. If you need to use a 4 inch vent pipe, I would buy a fan made for that application.
824985
No, it is not suitable for that application. You might want to try researching hydroponics ventilation to get an idea of what's out there. It is important for you to determine what kind of airflow you desire. Especially if it needs filtration for dust, smoke, or grease (cooking).
824986
No... It's a big fan and needs the full diameter of the housing. But Broan makes smaller fans that may meet your needs bng
824987
No. It moves a lot of air and it would be restrictive to go to a 4 inch duct.
824988
I don't think so, because you are constricting the air flow. It won't work at a 100% efficiency. I really don't know to much about duct work. I hope that helps.

Im thinking it could its two peices that slide together but I didnt install it so im not sure

I don't use a duct system because my shop is so small but many large tools on casters to move nearer to D/C. I use two Rockler 4" expandable hose (2' to 14') with blast gates at D/C to connect to tools I am using. A bit less efficient than permanent duct system connected to tools but I don't have the shop space so I move tools.

The way it is designed that may not be possible. what you might try is measure the extreme outside diameter, (OD) of each end and see what sizes are available.

I don't think so. I did not use a 4" rod. The fan is closer to the ceiling. My guess is right around one foot from ceiling..Give or take a few inches.

Yes, it comes with a small 5"+ section of duct plus the outside grill. If you need more than the 5" you will need to buy additional duct.

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.

Bernard, not positive if you can do so. Best to contact the company. If you look online, you should be able to locate customer service. I vented ours through the window and it worked very well. My guess would be that you would need a good seal around the vent tube to do so.

You would need to run a exhaust duct think it is four inch. It doesn't need to be insulated.

It is made for a 6" - however your HVAC contractor can build a transition to make it suitable for a 4" duct, which is what we did and it works well.

it is possible. the standard way to afix it to your vent is with a plastic bar (about 1/2" square) that goes across the opening, horizontally. shafts run from those two little knobs you see in the picture all the way back to the bar and sqweeze the vent to the wall. i did most of mine from the outside.

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

Hello. Try using either foil tape or, if you want to be able to take it down and reinstall on a regular basis, use wide rubberized clamps which seal the openings between the lint trap and duct. Try searching for FC4 mounting clamp for round 4" Duct (Pair). Good luck.

Yes absolutely. You will just have to do some math as to how big the duct opening is multiplied by the reading on the meter.
985724
Yes, the large round fitting you see in the picture is the vent to outside. you need to attach a hose, not included, or a piece of duct work from the fan outlet to an outside area.

No it will not. You need a 4"-6" duct transition. You can get one from Home Depot or Lowe's. Make sure that the Carbon filter is in range for thw version you buy. If the fan is too fast, then it will not properly scrub. If the filter requires more CFM, then you could potentially burn out the fan. That would take months though.

I see no reason that you couldn't, you would just have to support it. Could probably do that with rigid duct and sheet metal screws

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.
