Description
AC Infinity – CLOUDLINE S-Series
The AC Infinity CLOUDLINE S-Series Inline Duct Fan sets the standard for quiet, efficient, and reliable grow-room ventilation. Engineered for growers who need powerful airflow with minimal noise, the S-Series uses an EC motor paired with PWM (Pulse-Width Modulation) control to deliver smooth, precise performance while consuming far less energy than traditional AC fans.
Each unit includes an 8-speed manual controller, allowing you to dial in your airflow exactly as needed. The mixed-flow impeller design maintains strong performance even under high static pressure, making it perfect for use with carbon filters, long duct runs, and sealed grow environments.
Built for long-term durability, the CLOUDLINE S-Series features dual ball bearings, a detachable motor housing for easy cleaning, and an IP44-rated enclosure. Whether you’re running a compact tent or a full-room extraction system, this fan provides professional-grade climate control with whisper-quiet operation
