I was very skeptical with all the reviews stating it did not fit their inline fan.
I did not have this issue and was able to change my 6 inch ac infinity inline fan into 4 inch and vent out a dryer hole.

Heavy gauge of steel. Better quality than I expected. Highly recommend. Came very quickly too. Thumbs up

Mr.Martin:
Very sturdy and fits the fan and hoses just fine. I used it to upgrade my 6in filter to a 8in filter without having to buy a new fan. I know they say not to do this but I have been using this setup like this for over a year now with no smell issue or anything

I use 6in inline duct fans, a carbon and a HEPA filter for allergens and odors from the pets in the house (that NEED a bath every week and LOVE to roll around on the carpet). I recently read that using a smaller filter with a larger fan and using a reducer will increase the overall efficacy and CFM filtered (but require more frequent replacements, and the smaller filter has to support this high CFM rate), so I bought this reducer because the filter I bought was also from AC Infinity so I figured even though it is a little more expensive it is worth it to have matching equipment that will 100% fit. Well, IT DID NOT FIT! NOT AT ALL! I had to smash the sides down with a hammer and crimp the edges of it, and then bang on the top of it until it was forced into the filter because it would not fit over-top of it, and it would not fit inside of it. Completely incompatible. I was going to request a refund and get something else but after my work with the hammer and some duct tape I finally got everything together enough to use for now. But NOW I am going to have to buy a new reducer with my next filter because of this! Honestly just feels like I wasted $20 on something I...

Got this for my GF... Glowforge, not girlfriend.
While it's not an exact tight fit with the tubing for the external fan (also bought separate) If you throw some tape on there it works great. And MUCH cheaper than those that are made specifically for the external fan.

Matt:
I was concerned about the fit of this product onto the AC Infinity 6” but what I received fit perfectly on my Infinity as well as onto the filter I connected it to. I think there might be a couple of versions of this product out there. The image that Amazon displays and many of the images in the reviews are of a product that is silver colored with crimped seams. What I received is black with welded seams. Very heavy duty, and again a perfect, easy fit. I’ll try to remember to add a photo later.
