## 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
