This thing really moves the air when at high speed, so I keep it at mid or lower setting. This unit `was my solution to pull cold air upstairs to my addition in Florida. Before I found this solution, it was sweltering upstairs in summer. We put the unit in line with the ductwork and mounted it to the rafters so there was no ceiling vibration. This is the third time I have installed one of these because I have three ducts splitting from the AC trunk to three spaces upstairs. Now, all my air conditioning dreams have come true! It is nice and cool upstairs! The units run all day long. Love this product and would give it a higher rating off there was one! My next plan is to use one of these to pull more heat to my downstairs in my old, drafty historic home in Utah!` Review: My favorite option for a grow on a budget - Truthfully, if you're on a budget and still want that superior product, this is simply the best option. You don't need a fancy controller to start. You can start with this fan with its simple click controller and eventually work your way up, which is exactly what I did. I started by ordering this and the AC Infinity 6" Carbon Filter. Which is all you really need to run a good flower. However once you get your feet wet in your new environment and you want to start paying attention to things like VPD and regulate the climate, you can then upgrade to a more advanced AC Infinity controller! I upgraded to the Controller 67 and I'm eventually looking to upgrade to the 69 Pro. The fan comes with everything in the box that you need to connect it to the UIS AC infinity controllers. Now onto how I feel about this fan? I feel it's an absolute lifesaver. Speaking AFTER my previously mentioned upgrades, I am properly able to regulate & control the climate inside of my tent and achieve a proper VPD for flowering and my plants seem to love it! I use the 6" in a 4x4 and it works well, the only time I struggle is during lights off when the plants transpire water. I do think because of this, I would probably eventually upgrade this unit to the 8", However I would still stay with the Lite line. I really appreciate the flexibility in different ways you are able to use these fans with so many different controller options. I would recommend this to anybody looking for a GOOD quality budget inline fan for their grow set up. ## Features - Designed to quietly ventilate grow tents, exhaust odors, transfer heating/cooling to rooms, and cool AV closets. - Features the same build quality and innovations as the CLOUDLINE Series delivered in a value package. - Includes a wired 10-speed fan controller; also compatible with all CLOUDLINE Series smart controllers. - Mixed flow design combined with an EC-powered motor for a truly quiet and energy efficient performance. - Duct Size: 6" | Dimensions: 7.9 x 12.6 x 8.4 in. | Airflow: 352 CFM | Noise: 34 dBA | Bearings: Dual Ball ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09456J5CC | | Air Flow Capacity | 352 cfm | | Best Sellers Rank | #1,063 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1 in Hydroponic Ventilation Equipment | | Blade Length | 6 inches | | Blade Material | Plastic | | Brand | AC Infinity | | Brand Name | AC Infinity | | Collection Name | Inline Duct Fans | | Color | Speed Controller for A6 | | Control Method | App | | Controller Type | Button Control | | Customer Reviews | 4.7 out of 5 stars 739 Reviews | | Electric Fan Design | Exhaust Fan | | Electric fan design | Exhaust Fan | | Finish Type | Unfinished | | Included Components | Cord, Remote | | Indoor Outdoor Usage | Indoor | | Installation Type | wall-mounted | | Item Dimensions D x W x H | 7.9"D x 12.6"W x 8.4"H | | Material | Plastic | | Model Name | AI-CLA6 | | Model Number | AI-CLA6 | | Motor Type | EC | | Mounting Type | Downrod Mount | | Noise Level | 34 db | | Number of Blades | 10 | | Number of Power Levels | 10 | | Number of Speeds | 10 | | Part Number | AI-CLA6 | | Power Source | Corded Electric | | Product Dimensions | 7.9"D x 12.6"W x 8.4"H | | Recommended Uses For Product | Inline Duct Fan | | Room Type | Indoor | | Size | 6-Inch | | Special Features | Mixed Flow Design, Wired 10-Speed Fan Controller, Compatible with CLOUDLINE Series Smart Controllers | | Specification Met | CE, RoHS | | Style | Cloudline A6 | | UPC | 819137021754 | | Unit Count | 1 Count | | Voltage | 12 volts | | Wattage | 35 watts | ## Product Details - **Brand:** AC Infinity - **Color:** Speed Controller for A6 - **Electric fan design:** Exhaust Fan - **Mounting Type:** Downrod Mount - **Power Source:** Corded Electric - **Product Dimensions:** 7.9"D x 12.6"W x 8.4"H - **Recommended Uses For Product:** Inline Duct Fan - **Room Type:** Indoor - **Special Feature:** Mixed Flow Design, Wired 10-Speed Fan Controller, Compatible with CLOUDLINE Series Smart Controllers - **Style:** Cloudline A6 ## Images ![CLOUDLINE A6, Quiet 6” Inline Duct Fan with Speed Controller - Image 1](https://m.media-amazon.com/images/I/61zBgwoxcPS.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: What is the length of the speed control cord?** A: 5ft It look like an USB-C so maybe you can extend it. When disconnecting the remote the fan goes full speed, then back to previous setting when you reconnect it. **Q: How long is the adapter to use with the digital controller?** A: approx. 10 to 15 ft long **Q: One user stated that they wired directly to furnace blower, hence when blower comes on, it turn on, How? Any info please?** A: This is my plan for this product. You could do this in two ways. Assuming your HVAC furnace blower is the same voltage, 120VAC in the US, you could wire directly off the feed inside the furnace that powers the blower. This will require understanding of electrical wiring and/or electrical schematic of the furnace. Although unlikely, this method may overload the blower protection circuit and probably voids the furnace warranty. Alternatively, you could use the house thermostat fan signal to control a 24 VAC relay, such as Functional Devices RIBU1C, to switch the 120 VAC powering the duct fan. **Q: Any way to make it just go on full power instead of having to to push the button 5 times?** A: Push the button 5 times. The controller is set up to program fan speed on start up but will maintain the memory on a power loss event. If you don’t want to push the button 5 times then just unplug it. Then you can plug it in one time🤔 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome solution to pull more air into the room! *by D***P on April 9, 2025* Quiet, nice hum.

After some searching, I ordered the AC Infinity CLOUDLINE A6, and the difference is incredible! This fan efficiently pulls out smoke, keeping my work area clear and breathable. The speed control is a nice feature, but I keep it on the highest setting to ensure maximum smoke removal while my laser is running. As for noise, it’s surprisingly quiet, even at full power—you can hear it working, but it’s not distracting or overly loud. If you’re running a CO2 laser and need a reliable exhaust fan, I highly recommend this one. It’s a must-have upgrade that significantly improves airflow and keeps your workspace smoke-free! ## Frequently Bought Together - AC Infinity CLOUDLINE A6, Quiet 6” Inline Duct Fan with Speed Controller, EC Motor - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - AC Infinity Air Carbon Filter 6" with Premium Australian Virgin Charcoal, for Inline Duct Fan, Odor Control, Hydroponics, Grow Rooms --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/320969630-cloudline-a6-quiet-6-inline-duct-fan-with-speed-controller](https://www.desertcart.co.uk/products/320969630-cloudline-a6-quiet-6-inline-duct-fan-with-speed-controller) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-31*
