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

Needed a coupler in my dust collection system. This worked great. I feel like it might even reduce vibration a bit.

Works great as a coupler and absorbs noise/vibration ok. Found exact same item for half the price. Exact except logo

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.

Good quality, helps cut down on vibrational noises in between the charcoal filter and the inline fan. Worth it, every bit of noise reduction is needed since my grow tent is inside my bedroom

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.

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.

Disclosure: This was sent to me for free via the Vine program. I did not receive monetary compensation to write this review, just the product itself. Awhile back, I got an AC Infinity Air Filtration Pro CLOUDLINE 4 through the Vine program. When we set it up, almost everything about it was perfect. Except for one thing. When its time to connect the activated carbon filter to the air pump and the electronic controller, they provided you with...tape. Bear in mind, this is a $190.00 retail system and they included tape to attach things. Not even really duct tape, just standard tape. So when I discovered this, I begrudgingly put in for it. The grommet comes in a plastic bag. Its about 3-4 inches long with two pipe clamps on it that can be tightened by a Phillips head screw (Philips? I can never remember). To install, you remove the tape that previously anchored the carbon filter (poorly) to the air filtration unit. You then gently separate the carbon filter from the air filtration unit and slide this unit in-between. Then, you gently push the air filtration unit into the grommet and tighten the pipe clamp and repeat the same action on the other side for the carbon filter unit. The unit is made out of fairly rigid plastic aside from the flanges at the end so make sure everything is even as it doesnt have much bend to it. Then, revel in your HVAC prowess. Truth be told, this should have been in the box to start. Sure, its $13 but it should have been in the nearly $200 unit that I got before, not tape. So would I recommend getting it? Yeah, if you got the air filtration assembly previously and it had tape. But I would HIGHLY encourage AC Infinity to put this in the kits from the get-go. This is just nickel and dime-ing people at this point. I paid nearly $200 before, why should I pay an extra $13 for a part that should have been in there in the first place?

Helps quite a bit with fan noise. Sturdy construction. Everything Id expect from AC Infinity

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.

I am impressed that AC Infinity takes such a holistic approach to their products. If you are working on building a grow tent system, you can do it all with AC Infinity products, including tents, fans, lights, ducting and other hardware. We recently set up another tent and wanted to attach the outgoing fan to an activated charcoal exhaust filter. The option at the time was to just tape the filter to the fan with duct tape. That was NOT a great solution. It kept falling apart while I was trying to hang it in the tent. This clamp changed all that - it was easy to connect and holds the two parts together solidly, as if it were one unit. It is priced competitively with other brand couplers and is well made - like every other AC Infinity product Ive ever used.
