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

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.

Home Depot sells same ones for 4.50 maybe Amazon does too they should have at least made a 2 pack deal. Tonoricey. But still got one.

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

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.

Works great. Well packaged.

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.
