Product Description A grow tent air filtration system with all the necessary in-line components you need to ventilate your grow space. By assembling these essential pieces, this pack will help you quickly start your growth construction and take the guesswork out of buying them individually. This inline fan kit features the CLOUDLINE series fan that is able to deliver powerful yet quieter performance. Paired with a carbon filter with Australian virgin charcoal to prevent odors from leaking out of your grow tent. These two pieces are connected by a set of flexible ducts with four layers of protection to properly direct the airflow. Accessories include duct clamps, pre-filter cloth, rope clip hooks, and hanging straps to complete installation. The 69 Intelligent Programming Controller distributes intelligent programming to the inline silent fan to keep temperature and humidity under control and produce the optimal environment. Set dynamic programs that go beyond the on/off trigger and adjust fan speed in response to a changing indoor climate. Minimum reference levels keep the inline fan running at low speeds for even airflow, while timer, cycle, and schedule modes add custom activation on demand. Equipped with four ports to expand your airflow or add lighting for growing applications. Securely connect with the AC Infinity app via Bluetooth to remotely access your devices, unlock advanced programs, set alarms, notifications, view historical charts, and export CSV data. Quiet and Energy Efficient Design The included CLOUDLINE series inline fan features a PWM-controlled EC motor, allowing smooth operation at low RPM speeds without additional heat or noise. Achieve high performance airflow adjustment for grow tents thanks to its mixed flow design and its use of stator blades and hydrodynamic wind circles. Dual ball bearings give this inline fan a 67,000-hour lifespan that is backed by its IP-44 rating, resists dust and liquid splashes. Product ID Manufacturer AC Infinity Inc.

Review: I’ll start by saying this, if you are worried about discrete packaging then I’ll put your minds at ease. When you checkout there is an option to have your item shipped packed in a plain desertcart box. Do that and your worries are at an end. BUT that’s not that important because it seems ac infinity has thought of this and no longer packages these with a big advertisement of what’s inside. It does have a SMALL logo on either end of the plain box and in very small letters it says air filtration system but aside from that no big deal. I still opted for the desertcart box because I don’t want people getting the wrong idea. Now on to the actual product itself. Quality is top notch as always. Yea you can hear the fan on the highest settings but on 6 and below it’s very VERY quiet for the amount of air this unit moves. You’re really getting some high quality equipment here. Now onto the app. So far I’m very pleased with it. I grow sarracenia and I start thousands of seedlings in a grow tent for about a year before they go outside for their first dormancy. While a carbon filter isn’t really necessary for these plants, an exhaust fan is because they naturally like lots of light. The grow light I’m using doesn’t generate a ton of heat but on a warm day the temps can rise past 80 and I prefer to keep my plants in the mid to high 70’s. This fan and controller have allowed me to keep my climate within precise parameters from ANYWHERE. I love being able to monitor my tent while I’m at work. It definitely offers peace of mind. Well worth the money spent! If I were to purchase the inline exhaust fan, controller and other extras seperate it would definitely add up to more than this whole kit. The way I see it the carbon filter is a nice extra. Like I said I don’t need to get rid of any smells but I set it up to filter incoming air when the exhaust fan comes on when the temp rises above 80F Ac infinity always impresses me with their quality and attention to detail. It really is top notch. You can’t do any better. I’d be amazed if any of the similar units are anywhere close to this level of quality. ## Features - An air filtration kit with everything you need to cool, ventilate, and control odors in your grow space. - Features an AI-powered controller that analyzes climate patterns and anticipates spikes to program the inline fan dynamically. - Connect this controller to the WiFi app for access to real-time AI insights, guides, chatbot, and more from anywhere. - 4-inch inline fan with PWM-controlled EC motor for quiet and energy-efficient ventilation, rated at 205 CFM airflow and 29 dBa noise. - Australian carbon filter with gunmetal finish and flexible ducting traps odors while routing stale air away from your grow tent. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09TS4KC41 | | Brand Name | AC Infinity | | Capacity | 210 Cubic Feet Per Minute | | Color | Black | | Customer Reviews | 4.6 4.6 out of 5 stars (393) | | Frame Material | Alloy Steel | | Included Components | AI Powered Driver, 4 Inch Inline Fan, Carbon Filter, Flexible Ducts, Duct Clamps, Pre-Filter Cloth, Rope Clip Hooks, Hanging Straps | | Inner Material | Steel Wire | | Item Dimensions L x W x H | 30.2L x 17.6W x 19H centimeters | | Item Type Name | Bundle | | Item Weight | 8.41 Kilograms | | Manufacturer | AC Infinity | | Manufacturer Part Number | AC-FKT4 | | Model Number | AC-FKT4 | | Outer Material | Polyester | | UPC | 819137022911 | ## Product Details - **Brand:** AC Infinity - **Colour:** Black - **Frame material:** Alloy Steel - **Item weight:** 8.41 Kilograms - **Product dimensions:** 30.2L x 17.6W x 19H centimeters ## Images ![Air Filtration PRO Kit 4, Inline Fan, VPD Humidity Temperature Control, WiFi, Carbon Filter, Ducting, Curtain Ventilation System - Image 1](https://m.media-amazon.com/images/I/61Hi6dOyN3L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Will this be good for 48"X24"X60" tent ?** A: I use in a 4x4 tent works great. **Q: For the manufacturer: I’d like this ventilation kit in the 4” size, but with the wifi version of the controller. Is that possible?** A: Yes totally possible. I think its about 160ish with the remote as well. I opted for the speed controller bundle instead of the wifi controller and i regret not going with the better one. So good thinking on your part to go ahead for the better one. **Q: Is there a warranty available on this it is not showing up when i addit to my cart ?** A: All of AC infinity products, except consumables, are under a 2 year warranty. You just have to provide the order number, and confirm your address and AC infinity will replace or repair the defective product. Very easy replacement **Q: Is the filter also inline with a 6" inlet and 6" outlet?** A: The filter can be utilized either pulling air out, or pushing air in with the inline fan. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by H***L on 25 June 2025* Absolutely Nice! ### ⭐⭐⭐⭐⭐ Review *by A***W on 9 July 2023* I’ll start by saying this, if you are worried about discrete packaging then I’ll put your minds at ease.

Das Set ist durchdacht, hochwertig verarbeitet und sofort einsatzbereit. Der Aktivkohlefilter arbeitet absolut zuverlässig – selbst bei starkem Geruch wird alles sicher neutralisiert. Der Lüfter läuft überraschend leise, was für mich ein großer Pluspunkt war. Die Steuerung über das UIS-System ist genial – besonders mit dem automatisierten Temperatur- oder Feuchtigkeitstrigger kann man das System perfekt anpassen. Auch die Montage war unkompliziert, alles passt exakt. ✅ Highlights: • Starke Geruchsfilterung durch hochwertigen Kohlefilter • Sehr leiser Betrieb bei hoher Effizienz • Super einfach integrierbar in bestehende AC Infinity-Setups • Langlebige Komponenten, kein Billigkram ❌ Hinweis: Wer nicht das ganze UIS-System nutzt, kann sich evtl. anfangs etwas in die Steuerung reinfuchsen – lohnt sich aber! Fazit: Wer einen professionellen und leisen Luftfilter für sein Grow-Zelt sucht, kommt um dieses Set kaum herum.
