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

Some people complain about how it fits but they’re just ignorant. It’s designed to bridge the size difference so when you see it reducing on one end you know it’s working. Eliminates vibration noise and seals it up tight.

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.

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.

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

I have always taken a pretty lazy approach to my fan/filter setup and just set the fan on top of the filter letting gravity keep them together. It was finally time to get a clamp to make it secure and give me the option to hang the whole unit and choosing AC Infinity was a no brainer. Ive never had any issues with any of their stuff over the years so I expected this to be no different, and was right. Its very secure which is why I ordered it so Id be happy with that alone but it actually does cut down the noise a bit so thats nothing to complain about. My fan is a serious all metal beefy unit so for it to dampen it is pretty good. If I ran it with the plastic fan I have it would probably silence it completely.

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

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.
