AC Infinity CLOUDLINE A6 Quiet Inline Mixed-Flow Duct Fan 6"

High-Value 6-Inch EC Inline Ventilation Fan with 10-Speed Controller

Providing reliable air exchange for medium grow tents (3×3 ft up to 4×4 ft) doesn't require high energy bills or excessive noise. The AC Infinity CLOUDLINE A6 combines the premium build quality, mixed-flow design, and EC motor efficiency of the CLOUDLINE series into an outstanding value package. Delivering 352 CFM (598 m³/h) of airflow, the A6 efficiently pulls air through carbon filters while drawing an average of just 35 Watts.

Driven by a digitally controlled PWM EC motor, the A6 operates at a quiet 34 dBA, avoiding the motor hum and vibration associated with standard AC fans. Its mixed-flow impeller, stator blades, and hydrodynamic wind circles generate solid static pressure (394 Pa) to push air cleanly through ducting runs and light traps. Supplied with a wired 10-speed controller and a UIS™-to-Molex adapter dongle, the CLOUDLINE A6 integrates seamlessly with smart controllers like CONTROLLER 69 for automated climate programming and app connectivity.

Pro-Tip: Pair the CLOUDLINE A6 with a 6-inch AC Infinity Australian Carbon Filter in a 3×3 ft or 4×4 ft tent for total odour control with low energy consumption.

What Makes It Stand Out

• Quiet 34 dBA EC Motor: Digital PWM speed control eliminates humming and motor whine, allowing smooth operation across all 10 speed levels.
• High-Efficiency 352 CFM Airflow: Efficiently exchanges air (598 m³/h) to manage humidity, heat, and odour in medium cultivation environments.
• Mixed-Flow High Static Pressure: Stator blades and hydrodynamic wind circles push air cleanly through carbon filter beds and restrictive ducting (394 Pa static pressure).
• 10-Speed Controller Included: Provides precise speed control with built-in backup memory that saves your speed setting during power disruptions.
• UIS™ Platform Integration: Supplied with a UIS adapter dongle to connect directly into AC Infinity smart controllers for dynamic climate scheduling and mobile app management.
• Vibration-Damping Base & Easy Maintenance: Features a plastic mounting base to reduce fan vibration noise, while the central motor box unclips for simple cleaning without disturbing ductwork.
• 67,000-Hour Rated Industrial Build: IP44 rated against dust and moisture splash, backed by dual ball bearings for vertical or horizontal installation.

Real-World Applications

• Standard Grow Tents (3×3 ft & 4×4 ft): Primary exhaust fan for temperature, humidity, and odour extraction under LED fixtures.
• Active Intake Booster: Delivers fresh, filtered air into larger grow spaces to balance static pressure loads.
• A/V Closet & Attic Exhaust: Quietly exhausts heat build-up from home server racks, media closets, and domestic ventilation projects.
