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

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

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.

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.

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

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 well does the job

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

Will buy them for all my exhaust

Easy to install and helps with vibration and noise.

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