The fan runs quietly with minimal vibration, making it a great choice for my space. It was delivered on time, well-packaged in a custom box, and included everything I needed user manual, 2-year warranty, and mounting hardware for the speed controller. The fan’s cylindrical body is sturdy and well-crafted. The power cable and speed controller are seamlessly integrated, and the fan operates smoothly with very little vibration. The speed control is easy to adjust with a dial, ranging from OFF to maximum. At full speed, the noise level is similar to that of a pedestal fan, with the sound mainly coming from the airflow. This fan has steel blades and is designed for inline mounting in 8-inch ductwork. Note that there are no mounting brackets included. I’m using it at a medium speed to boost ventilation in my attic, aiming to improve my A/C system’s efficiency (I’m also adding a reflective radiant barrier). So far, it’s been performing great. For added convenience, I’ve connected it to an Amazon Smart Plug and can control it through the Alexa app or voice commands.

My house was filled with a strong smell as soon as you got within 20 feet of the door. After installing this filter and airing out the place, the smell was completely gone within an hour or two and hasn’t come back since. Pretty impressive, especially since I just harvested and the smell was at its strongest. I really appreciate the hooks for easy installation, and it’s way lighter than the previous filter I bought, which I paid more for. Hoping it lasts at least a year, and I’ll update once I know for sure!

I have been a customer since inline fans were the only grow equipment they sold. Since then, I have watched them blossom into one of the leading grow gear manufacturers in the world! There has only been a couple issues that were fixed almost immediately which is not normal for most big companies. they have earned my loyalty. Now if we could import the ordered from the ebay store and amazon store to get points that would be awesome as i could get me a really neat flag to represent the several complete ACI setups that i currently use. Oh well a dope flag wont keep me from buying from whichever store front saves me money as im close to $5000 in min.

these transmitters make my grow devices so much easier to move around when needed and cut down on wires everywhere

Iv enjoyed every product of yours but also the amazing customer service. Keep up the great work over there at ac infinity

I originally bought the S1 (80mm / 3" x 3") to cool an AV receiver, but it didn't fit my specific setup. However, it turned out to be a perfect USB desk fan. With a little help from my 3D printer, I created a stand to angle it slightly upward and a cradle for the controller. The airflow is just right, noticeable and refreshing without being disruptive, especially thanks to the three speed settings. It’s also completely silent and USB-powered, making it ideal for a home office. As a bonus, it will be easy to run off a rechargeable battery pack during hurricane season if the power goes out. Highly versatile

I picked up a set of the 10 gallon size back in August 2025, and they’ve been through everything South Florida weather can throw at them, torrential rain, relentless sun, and high humidity. Not once have they shown signs of rot or fabric breakdown. What really stands out is the build quality. The material is noticeably thicker than other fabric pots I’ve owned, and the handles are rock solid. Even when fully loaded with wet soil, I’ve never had a handle rip or stitch pop. That alone sets them apart. I’ve grown everything from dragon fruit and passion vine to potatoes and green onions in these, and the plants always seem to thrive. The fabric breathes beautifully, so water drains freely and roots never sit in soggy soil. I’ve also noticed that when placed directly on bare earth, fine roots will grow through the bottom—something that actually helped keep my plants hydrated during those scorching weeks when I forgot to water. The sizing is honest too. These are genuinely 10 gallons, not a half size knockoff. My only minor gripe is that over time, the sides start to bulge outward at the base. It hasn’t caused any tearing, but a thin support ring would help them keep their shape longer.

I’m really impressed with the IonFrame EVO4. I’m currently using it in my 5x5 grow tent, and while I’m planning to add more lights as my setup grows, this unit has performed flawlessly from the start. As a research scientist, I spent years researching grow lights before making a decision, and the attention to detail on this one immediately caught my eye.

Works good

Installed last month, it runs perfectly with strong airflow and simple controls. Be warned: it gets loud at top speed. Remember to place it near a vent (it's an exhaust fan) and consider pairing it with an intake fan for best circulation.

All was good.

I purchased the AC Infinity CLOUDLINE PRO S4 to vent toxic fumes from a Falcon A1 laser engraver from my son's home. Safety was the priority, and this fan delivered completely. The 4" inline fan is surprisingly quiet, with a 10 speed control ranging from silent to a gentle swoosh. It moves a substantial amount of air—comparable to a clothes dryer effectively pulling all fumes outside. Installation was straightforward using the included bracket, though routing the ductwork through the garage wall was the most time-consuming part. The build quality and packaging exceeded my expectations. It’s lightweight, well-made, and performs exactly as needed. For anyone needing reliable, quiet ventilation for workshops or equipment, I highly recommend AC Infinity and would buy this again without hesitation.

AC Infinity consistently delivers exceptional quality. The premium experience begins the moment you receive the product—even the packaging reflects their attention to detail.

Ac Infinity never disappoints

My house had poor air flow on the first floor. I installed an S10 cloud series fan (absolutely amazing!). Fixed my air problem. I didn’t order the controller pro and sensor until later and installed that. The controller allows all kinds of thresholds for controlling the fan. great system!

Got my thermal hose so I can use my heater outside tent it works great Keep my tent in check

Great quality and super easy to setup!

No complaints

I have multiple tents kits & other gear. Everything is great quality and their customers service is impeccable.

My Cloudline T4 has performed perfectly in my 3x3 veg tent for half a decade, remaining as quiet as the day I bought it. The natural progression was the Cloudline T6 PRO with the Controller 69, and it did not disappoint. Unifying control and having real-time environmental data for both tents on my phone is incredible. ACI has absolutely perfected the grow room fan.
