The AC Infinity CLOUDLINE PRO S12 is a powerful 12-inch inline duct booster fan that delivers strong airflow at 1604 CFM, making it well-suited for ventilation in grow rooms, HVAC systems, or cooling electronic closets. It operates relatively quietly at 62 dB, which is moderate noise for its size. Installation is straightforward for indoor use, and it comes with a wired 10-speed controller, plus it’s compatible with smart app controls for flexible operation.
Its EC motor is energy-efficient and keeps heat and noise low during extended runs, which is a plus for energy savings and comfort. The fan’s size and 12-inch diameter make it compatible with standard duct setups, though its nearly 18-inch length means some space is required for fitting. The mixed flow design helps maintain airflow even against some resistance, which is useful in complex duct systems.
The fan weighs 24.4 pounds, so it requires secure mounting. This fan is a good choice if strong, efficient airflow with adjustable speed controls is needed and a moderate noise level is acceptable.
The AC Infinity CLOUDLINE PRO S10 is a powerful and efficient 10-inch inline duct booster fan designed primarily for ventilation in hydroponic grow rooms and other indoor settings. With an impressive airflow of 1201 CFM, this fan is capable of effectively moving large volumes of air, making it ideal for environments needing robust ventilation. Its PWM-controlled EC motor ensures that the fan operates quietly, generating only 48 dBA of noise, which is a significant advantage for users who require a peaceful atmosphere, such as in grow tents or living spaces.
A highlight of this fan is its 10-speed wired controller, offering versatility in airflow management. The compatibility with UIS controllers allows for intelligent programming, which can enhance convenience for users wanting automated control. Its mixed flow design enables effective airflow delivery in high-resistance areas, which is beneficial for installations in complex duct systems.
There are a few considerations to keep in mind. The size of the fan (10 inches in diameter) may limit its compatibility with smaller duct systems, so it’s essential to ensure that it fits your existing setup. Despite its energy-efficient design, installation might require some technical know-how, especially for those unfamiliar with duct work or electronic controls. Additionally, while the noise level is relatively low, some users may still prefer absolute silence, particularly in intimate settings.
The AC Infinity CLOUDLINE PRO S10 is best suited for indoor applications where effective air circulation is needed, particularly in hydroponics or AV closets. Its strengths lie in its quiet operation, high airflow, and advanced control options, making it a solid choice for those needing efficient ventilation solutions. Just make sure to assess your space and installation requirements before purchasing.
The AC Infinity CLOUDLINE S8 PRO is a solid choice for boosting airflow in indoor spaces like grow tents, kitchens, or bathrooms. It offers a strong airflow of 807 CFM, which is good for moving a lot of air through 8-inch ducts, helping with ventilation or cooling tasks. One of its notable strengths is its quiet operation at 39 dB, which means it won’t be too disruptive in home or indoor grow setups. The fan uses an energy-efficient EC motor, which keeps power use moderate at 230 watts, saving on electricity compared to less advanced fans.
Installation is straightforward with its inline design fitting standard 8-inch ducts, and it’s compact enough to fit in tight spaces. The 10-speed wired controller provides flexibility to adjust airflow precisely, and it also supports smart controller options for more automated control, which adds convenience.
The unit runs on 12 volts and requires a corded power source, so it’s not cordless, which might limit placement flexibility unless power is nearby. While 39 dB is quiet for a fan this size, it’s not silent—some very noise-sensitive users might notice it. The plastic blades and lightweight build mean it’s not the most heavy-duty fan for extremely rugged use but works well indoors. This fan is especially beneficial for anyone needing reliable air movement in high-resistance duct runs, such as hydroponic growers or home ventilation setups. If you want a quiet, energy-efficient fan with good control options and compatibility with smart controllers, this model fits well. For fully cordless operation or ultra-low noise below typical fan sounds, other options may be preferable.
