Delivering up to 1604 CFM airflow at a whisper-quiet 62 dBA, it’s engineered with a mixed flow design for optimal performance in high resistance ducting. Perfect for hydroponic grow rooms, AV closets, and climate control applications, this metal-bodied fan combines energy efficiency, precision control, and durable dual ball bearings for long-lasting, professional-grade ventilation. ## Description Inline Duct Fan A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling, circulate fresh air, exhaust projects, and cool AV closets. Features an inline speed controller utilizing PWM-technology. Contains a mixed-flow design and EC-motor for a quiet and high static-pressure performance. The motor box containing the fan's impeller and blades can be detached for easy cleaning and maintenance. Complete kit includes one duct fan unit, one corded speed controller, installation manual, necessary mounting hardware, and a corded power adapter (UK 3-pin 220-240V AC Wall Plug - Type G). This product is a part of the UIS platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment. Precise Speed Controller The inline speed controller enables you to set the duct fan's speed to optimal noise and airflow levels for various environments. Unlike common AC-powered duct fans that suppresses voltage to control fan speeds, this fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation). This enables the motor to run smoothly at low RPM speeds without generating motor noises and heat. Eight-speed options are available with power on/off switch. Due to its backup memory capability, the fan can be triggered to run at custom speeds when given power. This S12 model can be connected to the CLOUDLINE T12 smart controller to share the same programming. Quiet and Energy Efficient Design The fan features a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating to deliver airflow in applications where air movement is restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be resistant to dust and liquids. Review: Added some ductwork in my house two years ago to help distribute the heat from the woodstove. This fan running 24/7, 6-7 months out ofthe year. Well worth the money compared to the units at H/D or Lowe's. Review: Read: if you have a 12” supply line running it the upstairs of your home and the air conditioner just isn’t pushing the air to the registers, get this!!! Installed one in a 2700 sq ft two story home with the furnace in the basement, there is now measurable air reaching the entire top floor. And the best part is you cannot hear it from outside the utility/mechanical room, even when running at full power. ## 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: 12” | Dimensions: 14.9 x 17.7 x 14.1 in. | Airflow: 1604 CFM | Noise: 62 dBA | Bearings: Dual Ball ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07X8QPX2T | | Customer Reviews | 4.3 4.3 out of 5 stars (61) | | Date First Available | 8 June 2022 | | Item model number | CLOUDLINE S12 | | Manufacturer | AC Infinity | | Material type | Metal | | Part number | AI-CLS12 | | Power source type | Corded Electric | | Product Dimensions | 35.81 x 37.85 x 44.96 cm; 11.2 kg | ## Product Details - **Brand:** AC Infinity - **Colour:** Black - **Electric fan design:** Blower - **Mounting type:** Wall Mount - **Power source:** Corded Electric - **Product dimensions:** 35.8D x 37.8W x 45H centimeters - **Recommended uses for product:** Cooling - **Room type:** Bathroom - **Special features:** Bladeless - **Style:** Industrial ## Images ![CLOUDLINE S12 PRO, Quiet 12” Inline Duct Fan with 10-Speed Controller, EC-Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - Image 1](https://m.media-amazon.com/images/I/61saOy+akkL.jpg) ## Available Options This product comes in different **Material Type, Style** options. ## Questions & Answers **Q: hello,i gonna use it in my grow room. do i really need the carbon filter while using this fan? if yes,can i use other brands carbon filter with it?** A: This machine just blows air in or out. The carbon filter get rid of smell. Two different things. Yes, you can use a different filter mix and match equipment. **Q: Is there no option to buy 2 fans and 1 controller?** A: No there is no option for buying 2 fans and 1 controller. If you do buy 2 fans I would get 2 s models and buy the controller separately. Saves a little bit of money and get the same results! **Q: I have read the reviews discussing the sizing issues with the inlet/outlet sizes being more 12.25 instead of 12. Has this issue been corrected?** A: If your trying to put that 12 inch flexible ducting you basically cant and just have to get aluminum tape. Its not that big of an issue though. With the tape it stays put. **Q: Can this fan be used to exhaust kitchen hoods (e.g. inline connected to a hood liner)?** A: I would not use such an expensive fan for a kitchen exhaust hood. The condensation and grease steam alone would gum it up and ruin it. They sell hood exhaust fans ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***L on 23 February 2025* Added some ductwork in my house two years ago to help distribute the heat from the woodstove.
