AC Infinity Noise Reduction Coupler with Stainless Steel Clamps, 8-Inch

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.

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 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.

Doesn't hurt airflow and nd makes machine quieter

High quality and connects my range hood 6" outlet and Vivosun carbon filter perfectly. No rubber odor is a plus.

Definitely needed.If you want to secure your inline fan to the filter without using tape. Works well super functional, easy to install it's only two screws. I believe it is a bit pricey though.

I purchased an S&P Powervent PV-150X remote mounted exhaust fan for a bathroom that I am renovating. The PV-150X fan is great but the "kit" didn't have anything to connect the 6" duct to the fan inlet and outlet. I found these rubber couplings and they were PERFECT. They fit the fan connections snuggly and the 6" duct was even tighter. The rubber used for the couplings was flexible and appears to be very durable. The stainless steel hose clamps were equally well made. Overall, the price was very fair for a quality product. And the packaging was great. They put a big foam donut in each coupling so that it would not get crushed out of shape. The rubber coupling will also help isolate any vibration when the fan is running.

Perfect method of joining the carbon filter and inline fan together. Docking a star because it should really just come with the fan/filter combo instead of being a separate purchase.

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.

Sin ruido del filtro al extractor

Used to connect the ventilation hose in my sailing boat to the inlet blower onboard. Excellent fit. Highly recommend it. Great value for money.

Sehr gute Qualität, passt einwandfrei - klare Kaufempfehlung.
