AC Infinity CLOUDLINE A8 Quiet Inline Mixed-Flow Duct Fan 8"

High-Capacity 8-Inch EC Inline Ventilation Fan with 10-Speed Controller

Ventilating medium-to-large grow rooms (4×4 ft up to 5×5 ft) and pushing air through dense carbon filters requires serious air-moving power without overwhelming noise. The AC Infinity CLOUDLINE A8 packs the core engineering, mixed-flow design, and EC motor efficiency of the flagship CLOUDLINE series into an incredible value package. Delivering a massive 724 CFM (1230 m³/h) of airflow, the A8 moves heavy air volumes with an efficient average power draw of just 72 Watts.

Powered by a digitally controlled PWM EC motor, the A8 runs smooth and quiet at 42 dBA, eliminating the annoying humming and vibration common in standard AC fans. Its mixed-flow impeller and stator blades generate high static pressure (746 Pa) to force air through long ducting runs and heavy carbon beds. Equipped with a 10-speed manual controller and an included UIS™-to-Molex adapter dongle, the CLOUDLINE A8 connects easily into smart controllers like CONTROLLER 69 for total app-based grow room automation.

What Makes It Stand Out

• High-Volume 724 CFM Performance: Delivers substantial airflow (1230 m³/h) to efficiently exhaust heat, humidity, and stale air from larger cultivation spaces.
• Quiet 42 dBA EC Motor Engine: Digital PWM regulation enables smooth, quiet operation without electrical hum or motor whine across all 10 speed settings.
• High Static Pressure Mixed-Flow Design: Features dual hydrodynamic wind circles and stator blades built to push air through thick carbon filters, silencers, and long duct runs.
• 10-Speed Controller Included: Offers precise airflow control with built-in backup memory that restores your speed setting after power cuts.
• UIS™ Ecosystem Integration: Supplied with a UIS adapter dongle to plug directly into smart controllers for Wi-Fi/Bluetooth app control, automated triggers, and VPD tracking.
• Vibration-Damping Base & Removable Hub: Polymer mounting frame absorbs fan vibration, while the central motor box detaches for effortless impeller cleaning without dismantling ducting.
• 67,000-Hour Rated Industrial Build: IP44 rated against dust and moisture splash, featuring dual ball bearings for vertical or horizontal installation in harsh environments.

Real-World Applications

• Medium-to-Large Grow Tents (4×4 ft & 5×5 ft): Primary extraction and odour control fan for intensive flowering cycles under high-output LED fixtures.
• Multi-Tent Shared Ventilation: Exhausts multiple smaller tents via duct manifolds into a single filtration line.
• HVAC Transfer & AV Closet Cooling: Moves large volumes of conditioned air between rooms, attics, or high-heat server closets quietly.
