AC Infinity CLOUDRAY S4 Ultra-Compact Auto-Oscillating Clip Fan 2-Pack 4"

Value Dual Pack of 4-Inch Auto-Oscillating EC Clip Fans with High Static Pressure Output

Maximise canopy circulation across multiple tent zones or dual setups with the AC Infinity CLOUDRAY S4 2-Pack. Engineered specifically for indoor grow spaces where clearance is at a premium, each 4-inch clip fan drives concentrated, high-velocity air movement across tight footprints (2×2 ft up to 2×4 ft). Powered by miniaturised EC motors and specialised high-static pressure impellers, each unit moves up to 204 CFM (346 m³/h) for a combined output of 408 CFM while drawing a frugal 11 Watts per fan.

Despite their compact size, both fans feature 10 digital speed levels, 10 motorised oscillation width ranges (up to 90°), and 10 dynamic natural wind modes that automatically fluctuate breeze strength to simulate outdoor weather. Built with carbon steel gears, dual ball bearings, and IP54-rated environmental seals, these fans operate reliably under continuous high humidity, heat, and airborne dust. Compact vise-grip metal clamps securely lock onto tent poles of any size without slipping or crowding plants.

What Makes It Stand Out

• Complete Dual-Zone Air Circulation: Includes two CLOUDRAY S4 clip fans, allowing simultaneous upper-canopy and under-canopy airflow management.
• Ultra-Compact 4-Inch Profile: Space-saving design fits into tight grow tents without crowding LED fixtures or plant leaves.
• High-Velocity Static Pressure Impeller: Pushes air further across foliage than standard fans, ensuring consistent circulation in tight spaces.
• 10-Level Automatic Oscillation (90° Range): Motorised auto-oscillation sweeps air smoothly across tent spaces while avoiding walls.
• 10 Dynamic Natural Wind Modes: Simulates natural outdoor breezes by varying fan speeds, strengthening stems and preventing wind burn.
• Miniaturised EC Motor with Steel Gears: Engineered with carbon steel gears and dual ball bearings for smooth, long-lasting motorised oscillation.
• IP54 Environmentally Sealed Protection: Designed for grow room use, completely protecting electronics from high humidity, moisture splash, and dust.
• UIS™ Smart Ecosystem Integration: Connects directly to AC Infinity smart controllers (such as CONTROLLER 69) for Wi-Fi/Bluetooth app controls, dynamic climate triggers, and VPD scheduling.

Real-World Applications

• Multi-Level Tent Circulation: Mount one fan near the light fixture to push down warm air and the second fan near soil levels to break up under-canopy humidity.
• Micro & Small Grow Tents (2×2 ft to 2×4 ft): Provides complete coverage for small setups without taking up growth volume.
• Seedling & Vegetation Stages: Use lower speed settings and natural wind modes to gently stress young plants and build thick stem structures.
