AC Infinity Noise Reduction Clamp 6-Inch, Duct Coupler with Stainless Steel Clamps, Flexible Rubber Coupling for Inline Fans and Carbon Filters in Growing and HVAC

Using it to connect an inline booster fan

Hooked up to a 4inch Mars Hydro fan and filter and fits perfect and very sturdy.It cancels out noise extremely well too.Cant wait to try the AC Infinity EC fan WITH this.

Works great. Well packaged.

Quick 2 minutes install that eliminated the duct tape connector I had made. Airtight seal to connect ducting/filtration systems. Such a small yet important piece of your grow. Has a ridge inside to stop from sliding too far and included two clamps to tighten it down.

Its a well thought out piece for the ac infinity inline unit. Although not necessary, it adds a clean look to the grow tent.

If you have an 8 inline fan and filter that you want a practically airtight and quiet connection, then this AC Infinity Noise Reduction Clamp 8-Inch, Duct Coupler with Stainless Steel Clamps will do just that and look professional and neat in the process. Made from quality materials and simple to install, do not hesitate to pick up this great accessory for your growing needs!

Now that product has actually arrived I can properly review it. Connector hose is a tight fit but you want that. So as a result it is a little difficult getting it seated on both ends. Product does work as advertised. I liked it so well I have ordered 2 more so I can make all fan to device connections. I do recommend this product.

Quality item but since it’s specifically manufactured for the connection between the carbon filter and the inline fan I believe the ac infinity team made one small error when designing this otherwise easily obtainable item from your common home improvement store. The carbon filter opening is “slightly larger” than the opening of the inline fan to allow the two to easily nest inside each other to make an otherwise solid connection if you’re not using this coupling. Once you proceed to connect the two it’s apparent that the inline fan has a few mm of space before it can be air tight once secured. The byproduct is the rubber has to bend in order to make a proper connection. It’s a minor caveat, but kinda lame nonetheless imho since you literally can go by a fernco coupling in the plumbing dept at lowes without the fancy branding for the same exact price. I bought this item assuming it was spec’d specifically for this task making it a more “precise fit”, I was wrong. All in all, I still recommend this item if you’re looking to either avoid using duct tape, or need the noise cancellation it helps provide since there is no price difference between this and a fernco coupling and you get the fancy ac infinity branding.

I have AC Infinity inline fan and carbon filter, so I figured getting their brand coupling would be a nice addition. Says perfect fit on package but its a lot bigger than the fans inlet.

This duct coupler works perfectly! It fits perfectly creating an air tight seal and noticeably reduces noise. I highly recommend it.
