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.

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

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

Fit both fan and filter reduced noise and sealed it up nice

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

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!

This is a great product. Its just thin enough to be flexible, and thick enough to be very sturdy. You can always rely on AC INFINTY to make quality products.

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

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.

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