The AC Infinity CLOUDRAY S is an oscillating clip fan designed for targeted air circulation in grow rooms, grow tents, and indoor gardening spaces. Built around a long-life EC motor with dual ball bearings and an IP54 rating, the CLOUDRAY S delivers reliable performance during continuous 24-hour operation in the high humidity and temperature extremes common in active grow environments. Its compact metal grip clip uses a vice grip-like design to secure tightly onto tent poles of any thickness without slipping, and can be mounted right-side up or upside down for flexible positioning.
Airflow is fully customisable across three dimensions. Ten speed levels control output intensity, ten dynamic wind modes vary airflow between levels to simulate the natural, irregular breezes of an outdoor environment, and ten oscillation levels determine the arc of movement from a focused narrow beam through to the widest possible coverage across the canopy. The fan head tilts and rotates across a 90° oscillation range and 55° tilt angle to reach any zone within the grow space without hitting tent walls or nearby equipment.
The CLOUDRAY S connects to any AC Infinity UIS controller via the included UIS extension cord, enabling climate triggers, timers, grow cycles, scheduling, and WiFi app control without any programming built into the fan itself. When connected alongside a CLOUDLINE fan and IONFRAME light, the CLOUDRAY S becomes part of a fully integrated, app-managed growing environment. For a grower looking to strengthen airflow through a dense canopy mid-tent without running additional ducting, positioning a pair of CLOUDRAY S fans at different heights and oscillation ranges achieves precise, targeted circulation with minimal space usage.

Directions for Use

Twist to remove the knob from the grip clip.
Position the grip clip on a tent pole or suitable anchor point.
Slide the fan's clamp neck into the grip clip and tighten the knob firmly until the fan is held securely. The clip can be mounted right-side up or upside down.
Adjust the fan head tilt angle: the head pivots upward 30° and downward 40° to direct airflow toward the desired zone.
Plug the power cord into a standard power outlet.
Press the speed button to cycle through speed levels 1–10.
Pressing past 10 returns the fan to 0 (off).
Press the oscillation button to activate automatic oscillation.
Press again to cycle through the 10 oscillation levels, from a narrow focused arc to the widest coverage range.
Press the dynamic wind mode button to cycle through the 10 wind modes, which vary airflow intensity between levels to simulate natural outdoor breezes.
To connect the CLOUDRAY S to a UIS controller, plug the included UIS extension cord into the fan's UIS port and connect the other end to an available port on the controller. The fan can then be managed via the controller's programming and the AC Infinity app. Note: the CLOUDRAY S does not support daisy-chaining between units. Multiple fans connect individually to separate UIS controller ports.
Clean the fan blades and housing periodically with a damp cloth to maintain airflow output.

The AC Infinity Cloudray S is easily the best oscillating clip fan I have used.
It has 10 speed settings, dynamic wind modes that better replicate natural airflow, and adjustable oscillation so you can control how wide an area it covers. The clamp is also significantly better than most clip fans, holding firmly to tent poles without constantly slipping or needing to be readjusted.
It moves a good amount of air, offers far more control than a standard clip fan and integrates directly with the AC Infinity UIS system.
For transparency, I am the owner of Hydro Oasis. I personally use AC Infinity Cloudray fans, and they are the oscillating clip fans I recommend above any other option I have tried.
