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

Works well does the job

Disclosure: This was sent to me for free via the Vine program. I did not receive monetary compensation to write this review, just the product itself. Awhile back, I got an AC Infinity Air Filtration Pro CLOUDLINE 4 through the Vine program. When we set it up, almost everything about it was perfect. Except for one thing. When its time to connect the activated carbon filter to the air pump and the electronic controller, they provided you with...tape. Bear in mind, this is a $190.00 retail system and they included tape to attach things. Not even really duct tape, just standard tape. So when I discovered this, I begrudgingly put in for it. The grommet comes in a plastic bag. Its about 3-4 inches long with two pipe clamps on it that can be tightened by a Phillips head screw (Philips? I can never remember). To install, you remove the tape that previously anchored the carbon filter (poorly) to the air filtration unit. You then gently separate the carbon filter from the air filtration unit and slide this unit in-between. Then, you gently push the air filtration unit into the grommet and tighten the pipe clamp and repeat the same action on the other side for the carbon filter unit. The unit is made out of fairly rigid plastic aside from the flanges at the end so make sure everything is even as it doesnt have much bend to it. Then, revel in your HVAC prowess. Truth be told, this should have been in the box to start. Sure, its $13 but it should have been in the nearly $200 unit that I got before, not tape. So would I recommend getting it? Yeah, if you got the air filtration assembly previously and it had tape. But I would HIGHLY encourage AC Infinity to put this in the kits from the get-go. This is just nickel and dime-ing people at this point. I paid nearly $200 before, why should I pay an extra $13 for a part that should have been in there in the first place?

Hooked up to a 4inch Mars Hydro fan and filter and fits perfect and very sturdy.It cancels out noise extremely well too.Cant wait to try the AC Infinity EC fan WITH this.

Works great as a coupler and absorbs noise/vibration ok. Found exact same item for half the price. Exact except logo

Good quality, helps cut down on vibrational noises in between the charcoal filter and the inline fan. Worth it, every bit of noise reduction is needed since my grow tent is inside my bedroom

This duct coupler works perfectly! It fits perfectly creating an air tight seal and noticeably reduces noise. I highly recommend it.

Using it to connect an inline booster fan

Easy to install and helps with vibration and noise.

Its a well thought out piece for the ac infinity inline unit. Although not necessary, it adds a clean look to the grow tent.

Needed a coupler in my dust collection system. This worked great. I feel like it might even reduce vibration a bit.
