I am extremely excited about how well it works. It was not very difficult for us to install it in my basement and vent it out through a window. It is super easy to use. It is not as loud and the air purifier I was using. I would recommend this fan over and over again. The way it is helping my laser not only function better but keep fumes and smoke out of my room is amazing for the price. This is a great value. It seems to more than powerful enough and is sturdy and looks well built. Review: AC Infinity CLOUDLINE PRO S6 – Quiet and Powerful Cooling for My Miner Room - I purchased the AC Infinity CLOUDLINE PRO S6, 6” Inline Duct Fan with Speed Controller to help keep my miner room cool, and it has exceeded expectations. The EC motor is both powerful and efficient, and what surprised me most is just how quiet it runs, even at higher speeds. Installation was straightforward, and the included speed controller makes it easy to adjust airflow as needed. Running multiple miners can heat up a room quickly, but this fan has made a huge difference — it keeps temps under control without adding a lot of noise or power draw. The build quality feels premium, and I can tell it’s designed to run continuously without issues. ✅ Pros: Very quiet operation, even at high speeds Strong airflow to keep miner room temperatures down Speed controller included for precise adjustment Efficient EC motor saves power over time Solid build quality, designed for 24/7 use ❌ Cons: Higher upfront cost compared to budget inline fans Speed controller cable could be a little longer 💡 Tips: Use insulated ducting to further reduce noise. Mount the fan with vibration-dampening straps for an even quieter setup. Pair it with a temperature or humidity controller for automatic adjustments. Clean the fan and ducts periodically to maintain peak airflow. Bottom Line: The CLOUDLINE PRO S6 is a top-tier ventilation fan that’s perfect for high-demand environments like mining rooms, hydroponics, or grow tents. It’s quiet, efficient, and powerful — exactly what you need for reliable cooling in a 24/7 setup. ## Features - Designed to ventilate grow tents, transfer heating/cooling to rooms, circulate air, exhaust odors, and cool AV racks. - 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: 6” | Dimensions: 7.9 x 12.6 x 8.4 in. | Airflow: 402 CFM | Noise: 32 dBA | Bearings: Dual Ball ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FPFVZTZ | | Air Flow Capacity | 402 Cubic Feet Per Minute | | Best Sellers Rank | #1,989 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1 in Hydroponic Ventilation Equipment | | Blade Length | 8.4 Inches | | Blade Material | Plastic | | Brand | AC Infinity | | Brand Name | AC Infinity | | Cable Length | 8 Feet | | Collection Name | Inline Duct Fans | | Color | Pro Speed Controller for S6 | | Control Method | App | | Controller Type | Button Control,App Control | | Customer Reviews | 4.8 out of 5 stars 5,493 Reviews | | Electric Fan Design | Exhaust Fan | | Electric fan design | Exhaust Fan | | Finish Type | Matte | | Global Trade Identification Number | 00819137020306 | | Included Components | Cord, Remote | | Indoor Outdoor Usage | Indoor | | Installation Type | Inline Duct | | Is Product Cordless | No | | Item Dimensions D x W x H | 7.9"D x 12.6"W x 8.4"H | | Item Weight | 0.01 Ounces | | Material | Plastic | | Model Name | CLOUDLINE S6 | | Model Number | AI-CLS6 | | Motor Type | Brushless Motor | | Mounting Type | Downrod Mount | | Noise Level | 32 Decibels | | Number of Blades | 10 | | Number of Power Levels | 10 | | Number of Speeds | 8 | | Part Number | AI-CLS6 | | Power Source | AC | | 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 | | Smart Home Compatibility | Smart Home Compatible | | Special Features | Programmable | | Specification Met | CE, ETL, RoHS | | Standby Power Shutoff | High Efficiency | | Style | Cloudline S6 | | UPC | 819137020306 | | Unit Count | 1.0 Count | | Voltage | 240 Volts | | Wattage | 38 watts | ## Product Details - **Brand:** AC Infinity - **Color:** Pro Speed Controller - **Electric fan design:** Exhaust Fan - **Mounting Type:** Wall Mount - **Power Source:** Corded Electric - **Product Dimensions:** 7.9"D x 8.4"W x 12.6"H - **Recommended Uses For Product:** Air Circulation, Cooling - **Room Type:** Kitchen - **Special Feature:** Water Resistant - **Style:** Modern ## Images ![AC Infinity CLOUDLINE PRO S6, Quiet 6” Inline Duct Fan with Speed Controller - EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - Image 1](https://m.media-amazon.com/images/I/515G8psanuL.jpg) ![AC Infinity CLOUDLINE PRO S6, Quiet 6” Inline Duct Fan with Speed Controller - EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - Image 2](https://m.media-amazon.com/images/I/61qh0zlE6ML.jpg) ![AC Infinity CLOUDLINE PRO S6, Quiet 6” Inline Duct Fan with Speed Controller - EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - Image 3](https://m.media-amazon.com/images/I/61B4-3IcMGL.jpg) ![AC Infinity CLOUDLINE PRO S6, Quiet 6” Inline Duct Fan with Speed Controller - EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - Image 4](https://m.media-amazon.com/images/I/61B8EwuR7nL.jpg) ![AC Infinity CLOUDLINE PRO S6, Quiet 6” Inline Duct Fan with Speed Controller - EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - Image 5](https://m.media-amazon.com/images/I/71CDBlYtPJL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: What is the range of cfm output, at different settings? can i bring it down as low as 100 cfm?** A: Hi there, Thank you for reaching out to us!

My system is probably just as complex as you'd guess: xTool P2 Laser, connected to a xTool filtration system, and then vented outside. That's three ducts (printer to filter, filter to fan, fan to outside) at 4", and the P2 itself is natively 3", but I bought an adapter on-line to make it 4". So overall, the fan works great, like wow! You can still hear it - it's not super quiet, but it's also not annoying. It's more of a louder "whoosh" than an annoying whine, if that makes any sense? And that's me running this fan at full-power, which is basically where I'm going to keep it at. It's possible that your needs won't be 100% all the time, and it is absolutely quieter at the slower speeds. The duct connections are perfect, and the 6" to 4" adapters I purchased here on Amazon were absolutely flawless and leak-free. As someone who buys a lot of high-end computer components, one of the things I really appreciated about all of the AC Infinity products (three ducts and this fan) is that it's well packaged, with a lot of accessories. It's almost like opening an iPhone, if iPhones came in dark packaging. It's also clear what this fan was designed for, as it came with a "how to grow hemp" manual, which made me laugh. There's a nice YouTube video on-line that explains how to set this all up specifically with the P2 (with details on the 4" to 6" leak-free custom adapters), and he tells you to get this model, and not the one that has all the bells and whistles (Bluetooth, WiFi, garbage disposal, toothbrush). I'm glad I got this exact model (S6 PRO). The remote is cool, and comes with a nice LONG (9') cable so you can put this wherever you want. You press the button once to turn it on, and it remembers the last settings (1-10) if you hold the power button for four seconds to turn it off. It's pretty cool! I love the design, and the fact that you can remove the center blower, to install the bracket on the wall, and then put the blower back in. Solid build quality. Overall, I'm very happy with this blower fan, and would absolutely recommend it for hydroponics and exhaust systems. ## Frequently Bought Together - AC Infinity CLOUDLINE PRO S6, Quiet 6” Inline Duct Fan with Speed Controller - EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - AC Infinity Flexible 6-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust - 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 --- ## 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.gr/products/71354164-ac-infinity-cloudline-pro-s6-quiet-6-inline-duct-fan](https://www.desertcart.gr/products/71354164-ac-infinity-cloudline-pro-s6-quiet-6-inline-duct-fan) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-25*
