is this 4inch or 6 inch duct?

Hi Anne, it's actually both. The duct is a tapered design starting at 4" and then gradually enlarging to 6" so it will accommodate either size.

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

The Panasonic FV-11VQ5 is made for 4" duct.https://www2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?storeId=11201

The outlet adaptor is about 5.75"; so, the pipe (the corrugated pipe for the existing air flow) is 6", if I recall correctly.

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.

It is 4 inch tubing. This is the standard size for dryer vents. Worked well for me, hope the same for you.

about 6 inches , i got a 4 inch fan. i would go for a 6 inch inline fan, the 4 inch one is not quite cuttin it.

Hi Eddie,If you mean the drainage tube, it is definitely less than 2.5". If you meant the exhaust tube that is quite large. I would say about 4".

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

Very strange, 5 inch ducking. A 6 inch piece of ducking will snugglly fit around the defualt ducking with ease, this is how I fixed my problem. Had to connect to an exsisting six inch ducting exhuast with a coupler and noticed the ducting was 5 inch. Very important to not decrease the diameter of the exhaust because the unit will reset itself if the air doesn't exhaust quickly enough and heat builds up as a safety feature. The exhaust line should never temp more than 90-95 degrees.

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

According to the installation instructions for the fan, it directs to install a circular duct (4 inches) to the adapter.

The unit has a 6" duct opening, but I have an adapter/reducer to a 4" duct line.

The inch's of the fan relates to the size of the incoming and outgoing ducting. So for this 8 inch unit. Its an 8 inch duct. All ducting is made to have a small amount of flexibility in the gap between connectors of the same size. This gap is usually closed with aluminum tape, or Duct Tape. Also depending of the temperature of the air being ducted. A layer of insulations might be used. Some ducting systems come with ducting and insulation in one.

the ducting fits right over either end of fan or both ends on the6 inch fan the ends are tapered

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

Frame, edge to edge, 6"x6". The part slips/fits inside a four inch vent pipe.

If you want to get technical, you will want to know the CFM (cubic feet per minute) of the fan you are using. If you have a 6 inch and a 4 inch fan with the same CFM, they will vent the same amount of air. You will need 6 inch ducting to attach to the hood, but that does not necessarily mean you can only use a 6 inch fan. I rigged this up to a lasko blower fan from walmart (~$45) and it does well.

Hi, Mike - the duct diameter is 4 inches. I used a regular 4" flexible dryer vent pipe to run to the exhaust vent. Thanks, Larry.
