I did measure a higher flow of air than advertised - a plus in the right direction. Easy to install and the fact that the fan has variable speed is also a big plus. Seems very well made, which means it should last a long time, check back in 15 years and we'll see how it did. Removing the fan unit to get to the mounting holes was real simple and the instructions laid that out nicely. I have another fan by this manufacturer in my greenhouse, and it works awesome. Was a good purchase - yep - a good purchase. Review: Improve HVAC Flow - Similar Design to Navy Submarine Ventilation System Fans - I liked the features of this fan, including the speed control. It's a superior design because it has rotor and stator blades inside the housing. This type of fan is quieter more efficient than a simple fan blade design, and it's similar to the ones we used on US Navy submarines. That should tell you they are quiet and move a lot of air. The housing on either end can be split from the center motorized fan module by removing a clamp. This allows for cleaning the fan or swapping out a bad motor. In theory, this feature simplifies a booster fan repair because once duct joints are assembled, especially in an HVAC system, they are difficult take them apart. I say "in theory" because you need to know how to use the clamps that hold the motor section to the inlet and outlet section. Loosen the screw until about 1/4 in of thread is showing below the nut. DO NOT unscrew the nut all the way. Leave the clamp assembled but loose. You sort of pop the clamp off, and when reassembling, you pop it back in place. It is similar to putting a bicycle tire on the rim. Note that the fan includes a second set of clamps, but these are used to attach existing ducting to the body of the fan. My application for this Inline Duct Fan was for HVAC ducts. Two legs of my system were fairly long and ducts were undersized. Installation was fairly simple. The set of steel duct clamps provided in the kit came in handy. I added mastic tape around the joint and activated the adhesive with hand pressure. Once attached, it's hard to take apart so I took my time to make a good seal and a mechanically strong joint. I needed to suspend my fan, so think about the mounting method before you get started. You could also use the metal bracket attached to the housing. I powered the fan with a relay circuit that energizes the booster fan only when the main HVAC unit comes on. I watched a YouTube video of someone else solving this requirement. I bought the relay on desertcart: RIBU1C Pilot Relay and use it to control both. At most, both fans draw 2 amps or less, well within the spec for this relay. After I finished the electrical work, I used the fan unit's 8 speed settings to adjust airflow and balance the HVAC system. I balanced the HVAC airflow by varying the speed on the fans. I have installed fans on two long duct runs. At fan speed 8 (max), the unit gets noticeably noisy, but it's also pushing a lot of air. You probably won't need top speed. In my system, setting the fan speeds at 3 to 5 balances the airflow. At this setting, the fan is very quiet and still pushes a lot of air. Airflow adjustments can be made with the speed controller. The rooms connected to the system are now much more comfortable. I'm ready for a hot summer! ## Features - Designed to ventilate hydroponic grow rooms, transfer heating/cooling, cool AV closets, and exhaust odors. - Features a wired 10-speed fan controller; also compatible with all UIS controllers with intelligent programming. - PWM-controlled EC motor provides quiet and energy-efficient performance with minimal heat and noise. - Mixed flow design with stator blade and hydrodynamic wind circles enables airflow delivery in high resistance areas. - Duct Size: 10ā€ | Dimensions: 11.3 x 15.1 x 12.2 in. | Airflow: 1201 CFM | Noise: 48 dBA | Bearings: Dual Ball ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07XBV5JY1 | | Air Flow Capacity | 1201 cfm | | Best Sellers Rank | #1,038 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1 in Hydroponic Ventilation Equipment | | Blade Length | 10 inches | | Blade Material | Plastic | | Brand | AC Infinity | | Brand Name | AC Infinity | | Color | Pro Speed Controller for S10 | | Connector Type | US Plug (NEMA 1-15 Type-A) | | Control Method | App | | Controller Type | Button Control | | Customer Reviews | 4.6 out of 5 stars 195 Reviews | | Electric Fan Design | Exhaust Fan | | Electric fan design | Exhaust Fan | | Finish Type | Matte | | Global Trade Identification Number | 00819137020856 | | Included Components | Cord, Remote | | Indoor Outdoor Usage | Indoor | | Installation Type | inline | | Item Dimensions D x W x H | 11.3"D x 15.1"W x 12.2"H | | Main Power Connector Type | US Plug (NEMA 1-15 Type-A) | | Model Name | CLOUDLINE S10 | | Model Number | AI-CLS10 | | Motor Type | EC motor | | Mounting Type | Downrod Mount | | Noise Level | 48 db | | Number of Blades | 10 | | Number of Packs | 1 | | Number of Power Levels | 10 | | Number of Speeds | 8 | | Part Number | AI-CLS10 | | Power Source | AC | | Product Dimensions | 11.3"D x 15.1"W x 12.2"H | | Recommended Uses For Product | Inline Duct Fan | | Room Type | Indoor | | Size | 10-Inch | | Special Features | Programmable | | Specification Met | CE, RoHS | | Style | Cloudline S10 | | Switch Type | Switch | | UPC | 819137020856 | | Voltage | 120 volts | | Wattage | 250 watts | ## Product Details - **Brand:** AC Infinity - **Color:** Pro Speed Controller for S10 - **Electric fan design:** Exhaust Fan - **Mounting Type:** Downrod Mount - **Power Source:** AC - **Product Dimensions:** 11.3"D x 15.1"W x 12.2"H - **Recommended Uses For Product:** Inline Duct Fan - **Room Type:** Indoor - **Special Feature:** Programmable - **Style:** Cloudline S10 ## Images ![CLOUDLINE S10, Quiet 10ā€ Inline Duct Fan with Speed Controller | Digital 10-Speed Control, EC-Motor, ETL-Certified, IP-44 Rated, Ventilation Exhaust Fan for Heating Cooling Grow Tents - Image 1](https://m.media-amazon.com/images/I/613HGgxqDJL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Does this work on 240V?** A: 110 **Q: How big of a room is this rated for to accurately control temperature?** A: I have a 12Lx 10w x 8 high with 20 plants how big of a fan do I meed to bring in fresh air and exaust please let me no. **Q: Is there a way to prevent Backdraft?** A: Inline baffle. **Q: El cloudline t10,se puede usar en el atico para ventilacion ?teniendo en cuenta que solamente la casa tiene agujeros de ventilacion en el techo** A: Si - nosotros lo utilizamos como booster para el HVAC de la casa, enlomar to uƱa rala segunda planta. ## Customer Reviews ### ā­ā­ā­ā­ā­ Good fan - moves a lot of air - quieter than some *by R***Y on February 23, 2023* The sad part about fans is they make noise, and it's hard to get away from that.

Higher CFM than hydro farm and others, looks better and A Lot quieter. The control has light on it but the cord is really long so it can easily go outside room. They include the Ducting clamps that you usually have to buy and the box even breaks down easily. Definitely worth the extra coupla bucks. ## Frequently Bought Together - AC Infinity CLOUDLINE PRO S10, Quiet 10ā€ Inline Duct Fan with Speed Controller - EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - AC Infinity Flexible 10-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust - AC Infinity Flexible 10-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust --- ## Why Shop on Desertcart? - šŸ›’ **Trusted by 1.3+ Million Shoppers** ā€” Serving international shoppers since 2016 - šŸŒ **Shop Globally** ā€” Access 737+ million products across 21 categories - šŸ’° **No Hidden Fees** ā€” All customs, duties, and taxes included in the price - šŸ”„ **15-Day Free Returns** ā€” Hassle-free returns (30 days for PRO members) - šŸ”’ **Secure Payments** ā€” Trusted payment options with buyer protection - ā­ **TrustPilot Rated 4.5/5** ā€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/168557420-cloudline-s10-quiet-10-inline-duct-fan-with-speed-controller](https://www.desertcart.ro/products/168557420-cloudline-s10-quiet-10-inline-duct-fan-with-speed-controller) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-09-10*
