## Overview

The AC Infinity CLOUDLINE S10 is a premium 10-inch inline duct fan engineered for professional-grade ventilation. Featuring a PWM-controlled EC motor with 8-speed precision, it delivers a robust 1201 CFM airflow at an ultra-quiet 48 dBA noise level. Its mixed flow design and dual ball bearings ensure high static pressure performance and durability up to 67,000 hours. Perfect for hydroponic grow rooms, AV closets, and HVAC applications, it includes a wired speed controller and is IP44 rated for dust and water resistance.

## Description

Designed to ventilate hydroponic grow rooms, transfer heating/cooling, circulate air, cool AV closets, exhaust odors. Features an 8-speed manual controller utilizing PWM. See T-Series for temperature and humidity controls. Mixed flow design combined with a PWM-controlled EC motor for a truly quiet and energy efficient performance. Kit also includes corded AC power plug, installation manual, and all necessary mounting hardware. Duct Size: 10” | Dimensions: 11.3 x 15.1 x 12.2 in. | Airflow: 1201 CFM | Noise: 48 dBA | Bearings: Dual Ball Product Description A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets. Features an inline speed controller utilizing PWM-technology. Contains a mixed-flow design and an EC-motor for a quiet and high static-pressure performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one duct fan unit, one corded speed controller, installation manual, and all necessary mounting hardware. 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 duct fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation). This technology enables the fan's motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers. Eight speed options are available with power on/off switch. Due to its backup memory capability, the fan can be triggered to run at customizable speeds when given power. This S10 model can be connected to the smart controller of the CLOUDLINE T10 to share the same programming. Quiet and Energy Efficient Design The inline fan features a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being 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 highly resistant to dust and liquids, and performs well even in harsh environments. Applications This quiet duct fan system is popular in a variety of applications including cooling AV equipment rooms, closets, racks, and cabinets. Due to its low noise and advanced control features, it’s also used in various air circulation and ventilation projects including hydroponic grow rooms and tents, exhausting bathrooms and attics, and other installations.

Review: 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!
Review: The sad part about fans is they make noise, and it's hard to get away from that. 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.
