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

Most useful for use with Portable Air Conditioners!
I had two issues once it came to connecting my portable AC’s Exhaust Duct to a window with Louvered Air Vent (1) Extending the Exhaust Duct by connecting it to another of similar diameter. (2) Connecting the extension to an Air Vent with an inlet of similar diameter. I tried numerous contraptions and wasted many hours, before I came to this one. And this has been a true life saver. It does both jobs amazingly well. Quality is second to none; as it appears to be robust and esthetically pleasing! Ordering another as a spare and highly recommended!

Used for Spider Farmer in-line Fan and Carbon Filter
Great product! It has dramatically decreased the noise and I don't need any tape to ensure 100% airtight. Looks cool too!

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

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.
