## Description

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 - desertcart.com

Review: great clamp for grow room exhaust - Not sure on the noise reduction portion but its a solid clamp and works well connecting my exhaust fan and the charcoal filter. been sitting solid for a few months now and unless the fan is running at 80% or higher you don't hear anything in the room or while walking past it. It doesn't obstruct the airflow and I feel like its pretty durable and will outlast my filter.
Review: Superior product, installs easily, holds well - Superior product, installs easily, holds well. I originally bought just two for installing the fan itself, but liked using them so much I bought three more to simplify other joins in the welding exhaust ducting I was constructing

Superior product, installs easily, holds well. I originally bought just two for installing the fan itself, but liked using them so much I bought three more to simplify other joins in the welding exhaust ducting I was constructing

### ⭐⭐⭐⭐⭐ Worth every penny!
*by J***. on February 3, 2026*

A MUST have to connect filter and fan!! Never again will I use duct tape!!! Took forever to get the already sealed tape off my filter/fan. Clamp was easy to install & fits like a glove. And it definitely reduces noise! It's not going to silence the fan; But I can definitely tell a "significant" difference! Can turn the fan up higher before hearing it as much, and even then it's still quieter than before.
