## Description

AC Infinity Noise Reduction Clamp 4-Inch, Duct Coupler with Stainless Steel Clamps, Flexible Rubber Coupling for Inline Fans and Carbon Filters in Growing and HVAC - desertcart.com

Review: Great quality - Puts duct and fan together perfectly, airtight, and provides support. Great quality
Review: Worth every penny! - 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.

## Features

- Rubber pipe coupling designed to securely pair ducted components together while preventing air leaks.
- Matte black rubber construction is flexible, heavy-duty, and can easily fit over duct ports and piping.
- Minimizes noise by absorbing sound waves from fan vibrations and airflow traveling through ductwork.
- Creates an airtight seal and hold using adjustable stainless steel hose clamps with worm drive locks.
- 4 inch coupler fits inline fans and carbon filters with solid duct ports in growing and HVAC settings.

### ⭐⭐⭐⭐⭐ great clamp for grow room exhaust
*by W***L on December 30, 2025*

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.
