Are the duct fan holes 4" or 6".

6 in and I just shoved a small fan at Walmart in and connected the tube to the window. It gets a good enough air flow through the room and materials strong enough to hold it all up. It's a great little fan for the money

The duct fan holes are for 6" stove pipe. If you have a fan it will fit 6 " as well.

It connects to a six inch duct. You could reduce it with a fitting but this would also reduce the fan's output.

Yes. This is very common. Any HVAC supply, big box hardware or probably Amazon will sell this. But it is recommended to keep the duct run at 6" for as long as possible to move more air.

I think 6 inch was the standard size. The contractor went into the attic to brace it and used the existing duct work.

4 inches center to center for inlet to outlet 6 inches overall, sorry for being so late.

Hi Jeff, I have not installed the fan yet so I couldn't tell u the exact size of the hole needed. Im waiting for the cooler weather to do the install. Sorry I couldn't be more helpful.

Hi Joe: I had my electrician install both of these fans and I will say that honestly I do not know but.....I had him replace my 4" to a 6", it is a very inexpensive hose.

I don't know, but they fit in the same hole as the air conditioner. I removed this and placed the fan.

Hole pattern and size are the same as 120 mm fan. You can use fan screws to attach it to a 120 mm fan. Distance between holes are 105mm and holes are 5mm.

The holes for mounting are 6 inches for the bottom and 3 inches for either side.

Felickz, I guess I misspoke about the size of the vent piping size, Which this fan does vent 6". I also recommended using the Broan 636 fan-jack but meant to use the Broan 634 fan-jack for roof installation or if venting sidewall use the Broan 843 which both have a back draft dampers. Hope this clears this up!!! Mark Innovative HVAC Systems, Inc.

The fan measurements are 12.5" X 10" so the hole is slightly smaller than that. They do give you a pattern to use to cut the hole. Simple installation.

They just drop in the vent. There are no holes, so you would have to drill your own and modify the duct work.

The 4" duct size will not compromise the CFM rating as long as it is a short run, approximately 10' or less. For longer runs it is recommended to use the 6" duct size to maintain proper air flow and allow the motor to achieve the 110 CFM.

From the ceiling to the top of the fan body is 6 &3/4 inches. Hope that answeres your question.
