AC Infinity CLOUDRAY S4 Ultra-Compact Auto-Oscillating Clip Fan 4"

Ultra-Compact 4-Inch Auto-Oscillating EC Clip Fan with High Static Pressure Output

Engineered specifically for grow tents where space is at a premium, the AC Infinity CLOUDRAY S4 delivers concentrated, high-velocity air movement in micro-grow spaces and tight setups (2×2 ft and 2×4 ft). Powered by a miniaturised EC motor and a specialised high-static pressure impeller, this compact 4-inch fan drives up to 204 CFM (346 m³/h) of targeted circulation while drawing a maximum of just 11 Watts.

Despite its small form factor, the CLOUDRAY S4 comes fully equipped with 10 digital fan speeds, 10 motorised oscillation ranges (up to 90°), and 10 dynamic natural wind modes that automatically fluctuate breeze velocity to simulate outdoor airflow conditions. Its long-life brushless EC motor features carbon steel gears, dual ball bearings, and an IP54-rated environmental seal to comfortably handle continuous high humidity, heat, and airborne dust. A compact, vise-grip style metal clamp securely locks onto grow tent poles without slipping or crowding nearby foliage.

What Makes It Stand Out

• Ultra-Compact 4-Inch Profile: Space-saving design fits effortlessly inside small or crowded grow tents (2×2 ft setups) without interfering with LED grow lights or plant tops.
• High-Velocity Static Pressure Design: Optimised impeller geometry pushes concentrated air movement further across the canopy, delivering superior velocity compared to larger standard fans.
• 10-Level Automatic Oscillation (90° Range): Motorised auto-oscillation features 10 adjustable width ranges to sweep smooth, even air movement across tight spaces while avoiding tent walls.
• 10 Dynamic Natural Wind Modes: Simulates outdoor wind patterns by varying fan speeds automatically, reducing environmental stress while strengthening stem wall structures.
• Miniaturised EC Motor with Steel Gears: Engineered with high-strength carbon steel gears and dual ball bearings to ensure long-lasting motorised oscillation.
• IP54 Environmentally Sealed: Built to withstand harsh indoor grow environments, fully protecting internal electronics from liquid splash, high humidity, and dust.
• UIS™ Smart Ecosystem Integration: Connects directly to AC Infinity smart controllers (such as CONTROLLER 69) for Wi-Fi/Bluetooth app access, climate triggers, timers, and automated VPD programming.

Technical Specifications

Real-World Applications

• Micro & Compact Grow Tents (2×2 ft & 2×4 ft): Primary circulation fan engineered specifically for tight footprints where space around the canopy is minimal.
• Under-Canopy Spot Ventilation: Mounts low on vertical tent poles to eliminate stagnant humidity pockets around soil beds and lower leaves.
• Seedling & Propagation Spaces: Delivers ultra-gentle wind speeds on lower settings to encourage early root and stem development without wind-stressing young clones or seedlings.
