What size duct conneciton does this use? 4" or 6"?

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

6" ducts are required. This unit has a variable speed motor that adjusts itself to move 130 cubic feet per minute. I must say that both of mine are absolutely awesome at controlling the humidity in our large bathrooms.

sorry i nno longer hae this fan, it is defintly 6 inches. you may need to go with the 4 in one

there is a add-on reducer from 6" down to 4". Without the reducer its a six inch connection. HTH. John

The RadonAway XP201C is listed as mating to a Duct Diameter of 4". Fantech is slightly larger at 4.5". I use Fernco-type unions to mate the Fantech to the PVC pipe. The Fernco can stretch. You will drive yourself crazy at Lowes or Home Depot trying to find PVC fittings that fit the Fantech!

Nothing bigger than #6. I used red & black welding cable - very flexible - about $.50/foot.

Just the 6" duct work to connect the humidifier to the HVAC system. The Aprilaire 600 installed on my return air side, so I ran the 6" duct work to the supply side. I was able to electrically connect the unit to my Carrier Infinity System painlessly.

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

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.

It is standard 4" dryer duct. The duct goes director into the unit. Works great.

Jimmy, I am using 4" duct (actually sewer pipe) through out my shop) and it is proving very effective) with gates to limit the collector to one machine at a time. I can't say that it won't work, but it will not be as effective since the airflow is limited by the 4" connection. Not worth the $.

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.

4 inch diameter. Works well with our batch feed operation garbage disposer.

The fan is rated at <.3 sones into a 6" duct. You could buy an adapter for 4" duct but that will increase the static pressure of the system. This fan is designed to compensate for the higher pressure by increasing the speed of the fan to maintain the CFM rating but it will cause increased noise.

These are perfect for ducts that are 3 inches in diameter. They're hard to find since most hardware stores only stock the 4 inch ones for dryers

This fan doesn't have an "adapter" per say. It is made for a standard 4" duct. If you have a 6" you would need a reducer to 4".

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