## Description

AC Infinity Noise Reduction Clamp 8-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

### ⭐⭐⭐⭐⭐ AC Infinity products are the best
*by N***N on September 8, 2024*

I got this for a 4" exhaust fan in a small grow box and it works great. I have it in between the fan and a carbon filter. The rubber is very thick and does a great job of reducing noise from vibrations of the fan. The clamps that come with it are solid and keep a tight seal on the fan and filter. All of their products are fairly priced and this is no exception. Quality product at a great price makes this a must have. Nothing to dislike about this product whatsoever.
