AC Infinity Cloudline PRO Inline Fan with Speed Controller (S Series) The AC Infinity Cloudline PRO Inline Fan with Speed Controller is a high-performance inline extractor fan designed to provide reliable grow room ventilation and efficient airflow for indoor growing. Ideal for grow tents, grow rooms, and hydroponic systems, it helps maintain stable temperatures, humidity, and fresh air circulation for healthier plants and improved yields. Effective ventilation is essential for successful indoor cultivation. Without consistent airflow, heat builds up, humidity rises, and stale air limits CO₂ availability, increasing the risk of mould, mildew, and plant stress. The Cloudline PRO delivers continuous air exchange to create a balanced growing environment throughout every stage of the grow cycle. The included 10-speed manual speed controller gives growers precise control over airflow, making it easy to adjust ventilation as environmental conditions change. Increase extraction during hotter periods or reduce airflow when temperatures are lower to maintain optimal growing conditions and support consistent Vapour Pressure Deficit (VPD). Powered by a premium EC motor, the Cloudline PRO delivers powerful airflow with exceptionally quiet operation while consuming less energy than traditional AC extractor fans. The efficient motor also offers improved reliability and a longer operating lifespan, making it ideal for continuous use. Its mixed-flow fan design is engineered to maintain strong airflow even when connected to carbon filters, silencers, and ducting, ensuring excellent ventilation performance in high-resistance grow room systems. As part of the AC Infinity UIS™ ecosystem, the Cloudline PRO can be upgraded with compatible smart controllers, including the AC Infinity Controller 69 PRO, allowing automated climate control based on temperature, humidity, and VPD without replacing the fan.
