Cloudline S8 AC Infinity Fan with Speed Controller

The AC Infinity CLOUDLINE S8 is a high-capacity 8-inch inline duct fan engineered for growers, HVAC users, and AV system builders who need powerful airflow with ultra-quiet performance. Delivering up to 740 CFM, the S8 is ideal for larger grow tents, hydroponic rooms, AV closets, and whole-room ventilation projects.

Its mixed-flow design, paired with a PWM-controlled EC motor, ensures smooth, energy-efficient operation even in high static pressure environments. The included 8-speed manual controller allows precise airflow adjustments without the noise and heat associated with AC-powered fans. With a detachable motor box for easy cleaning, dual ball bearings rated for long life, and an IP44 dust/liquid-resistant housing, the CLOUDLINE S8 provides dependable, low-noise ventilation for demanding air-exchange applications.
