Grower Tip
- Start with gentle airflow for seedlings, then increase the speed through vegetative and flowering growth.
- Adjust the oscillation range so the fan sweeps the crop without contacting the tent walls.
- Unplug before cleaning; wipe the grille and blades with a damp cloth, then allow them to dry.
Features
Ten speed levels and ten Dynamic Wind modes let you tailor circulation for different growth stages.
Ten oscillation levels provide targeted airflow or a sweep up to 90° while helping the fan avoid tent walls.
The 100mm impeller delivers up to 204CFM from a compact 24.7 × 30.0cm fan unit.
The EC motor uses dual-ball bearings, while the IP54-rated housing resists dust and liquid ingress.
Connect the fan to compatible UIS controllers for temperature, humidity, timer, cycle, schedule and app-based control.
The grip clamp secures to a grow-tent pole, with horizontal or vertical mounting positions.
-
1
Assemble the clamp
Remove the clamp knob, slide the fan swivel into the grip clip, then replace and tighten the knob.
-
2
Secure it to the pole
Loosen the grip, position it around a grow-tent pole and tighten it securely. Do not mount the fan upside down.
-
3
Connect power
For this 100mm model, connect the power adapter to the fan port and secure the twist-on fitting before plugging into mains power.
-
4
Set the airflow
Adjust the head and choose a speed from 1–10. Hold the speed button for at least three seconds to activate Dynamic Wind mode.
-
5
Set oscillation
Use the oscillation button to select levels 0–10 and keep the sweep within the tent walls.
-
6
Add smart control
For automated control, connect the UIS lead to a compatible controller; oscillation still requires manual activation on the fan.
What size is the CLOUDRAY S4 and how much air does it move?
The S4 uses a 100mm impeller and measures 24.7 × 30.0cm overall. Its maximum rated airflow is 204CFM, with ten speed levels available to reduce or increase circulation for the space and growth stage in an indoor grow.
Can I mount the CLOUDRAY S4 upside down?
No. Mount it horizontally or vertically on a grow-tent pole, but do not install it upside down. Tighten the grip securely and adjust the oscillation range so the fan does not contact the tent walls during operation.
Which AC Infinity controllers work with this fan?
The CLOUDRAY series is compatible with Controller 69, Controller 69 Pro, Controller 69 Pro+ and Controller AI+. These can add environmental programming and app control. Oscillation is still switched and adjusted manually on the fan.
What does Dynamic Wind mode do?
Dynamic Wind mode varies the fan between speed levels to imitate changing natural airflow. First choose the maximum speed, avoiding level 1 because it removes the usable range, then hold the speed button for at least three seconds.
How do I clean the fan?
Unplug the fan before cleaning. Unscrew the bottom of the front grille, rotate the grille anticlockwise and remove it. Wipe dust from the grille and blades with a damp cloth, let everything dry, then refit and secure the grille.

Product Description
A highly innovative clip fan designed to deliver targeted circulation and optimize each stage of your plant’s grow cycle. Get unprecedented customization capabilities for complete airflow control using this grow tent clip-on fan’s 10 speed levels, 10 dynamic wind modes, and 10 oscillation settings. The specialized compact motor achieves a higher wind velocity than that of larger clip fans (at maximum speeds), ensuring full space coverage. This product is a part of the UIS™ platform of grow devices and smart controllers, designed to unite with the AC Infinity app over WiFi to achieve your ideal environment.
Tailored, Custom Airflow
Access ten digital speeds plus ten dynamic wind modes for customizable airflow that varies between levels to simulate an outdoor environment, ensuring healthier growth with reduced stress on your plants. For even greater control, utilize the ten oscillation levels that deliver focused circulation to specific spots or offer the widest reach possible while avoiding obstacles. With this, you can set precise circulation for any plant growth stage, from ultra-gentle breezes for germination and seedlings to a powerful airflow for vegetative and flowering.
Compact Engineering
This clip fan utilizes a small form factor and a high static pressure design that produces superior circulation in tight spaces, delivering greater wind velocity when compared to larger fans. Its miniaturized EC motor with carbon steel gears and dual-ball bearings maximizes efficiency and control, ensuring strong, consistent airflow. A space-saving metal clamp with a vise-grip-style design ensures a dependable hold on tent poles.
