Really Nice. Extremely well made. Great product. Great Shipping. Great price.

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.

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.

If you've ever joined a fan to a filter with 6" of duct, you know how much better this item is.

This is for solid ductwork. It worked okay for my flexible duct.

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.

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

i love this brand, you never go wrong with them, good quality products and always listening to their customers

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.

Die AC Infinity Geräusch‑Unterdrückungs‑Manschette hat mich wirklich überzeugt! Sie ist hochwertig verarbeitet, sitzt perfekt um Rohrverbindungen und reduziert spürbar die Lüfter‑ und Strömungsgeräusche meines Systems. Die Materialien fühlen sich robust an und wirken langlebig — kein dünner, billiger Stoff, sondern ein stabiler Schalldämpfer, der durchdacht konstruiert ist. Was mir besonders gefällt: Effektive Geräuschreduzierung: Geräusche, die sonst unangenehm auffallen, werden merklich gedämpft — gerade bei höheren Lüfterstufen ein spürbarer Unterschied. Hochwertige Verarbeitung: Die Manschette besteht aus strapazierfähigen, isolierenden Materialien, die sich auch bei häufiger Nutzung nicht verfärben oder ausleiern. Flexible Passform: Sie lässt sich einfach über Lüftungsrohre oder Ventilator‑Anschlüsse ziehen und sitzt sicher, ohne zu verrutschen. Leicht zu installieren: Kein Werkzeug nötig — innerhalb weniger Minuten sitzt alles perfekt. Ich nutze die Manschette in Verbindung mit meinem Lüftungssystem und merke sofort, wie ruhiger es geworden ist. Besonders beim Betrieb in Wohn‑ oder Arbeitsräumen macht sich die leisere Umgebung positiv bemerkbar. Insgesamt ein sehr durchdachtes Produkt, das Haltbarkeit, Funktion und Komfort vereint. Klare 5 von 5 Sternen und absolute Empfehlung!
