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

Sehr gut verarbeitet, und passt genau

At first glance this may seem expensive. I bought two to mount my inline duct fan - same brand S6. These made the install simple as they slip along the duct allowing the fan to be inserted in the gap. Then they both slide back to engage with the fan before tightening the supplied clamps. The fan didn’t require any other support or fixings and the rubber deadens any vibration. There was no noise from this installation other than air movement based on how much air was moved. See my review of the S6 fan which is excellent. Final thought - the presentation in terms of the packaging was excellent.

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.

Super Qualität passt super, und hält dicht.

I was amused by the fancy packaging for a rubber clamp, they even thought to use a foam insert to prevent deformation. The clamp fit my Vortex Profilter flange snugly, but was actually a bit loose on the AC Infinity Cloudline S6. A little pre-tightening of the clamp prior to insertion solved the issue. These really simplified the process of building my DIY Air Purifier.
