AC Infinity CLOUDRAY S9 – 9″ oscillating fan with an EC motor

The AC Infinity CLOUDRAY S9 is a modern clip-on fan with a 9-inch (22.86 cm) diameter, designed for efficient and precise air circulation in grow tents. The second generation of this model has been improved in terms of durability, quiet operation, and the ability to precisely adjust airflow to the plants’ needs.

The unit utilizes an efficient, brushless EC motor, paired with carbon steel gears and dual ball bearings. The design ensures a long service life, energy-efficient operation, and reliability even in environments with elevated temperatures and humidity. The IP54 protection rating further protects the unit from adverse conditions inside the greenhouse.

Precise Air Circulation Control

The CLOUDRAY S9 allows you to very precisely adjust the intensity and pattern of air circulation to meet the current needs of your crop. Users have access to 10 speed levels, enabling them to set everything from a gentle airflow to an intense breeze.

Additionally, the fan offers 10 dynamic wind modes in which the airflow intensity changes automatically. This creates a more natural airflow, resembling the varying breezes found outdoors.

This solution allows you to tailor air circulation to different stages of plant development—from a gentle breeze suitable for young seedlings to much stronger circulation during periods of intensive growth and flowering.

10 levels of automatic oscillation

One of the most important features of the CLOUDRAY S9 is its advanced oscillation system. The 10 available settings allow you to control the area covered by the fan.

You can direct the airflow to a specific part of the growing space or choose a wider range of motion to ensure circulation over a larger area. The adjustable range also helps you position the unit so that it avoids colliding with tent equipment while oscillating.

The maximum rotation range is 90°, while the tilt angle can be adjusted up to 55°.

Upgraded EC Motor and Durable Construction

The second-generation CLOUDRAY S9 features a larger and more durable EC motor, whose design has been optimized for long-term operation and frequent use of the oscillation function.

Brushless motor technology combines high performance with low energy consumption. The fan draws a maximum of 11 W while achieving an airflow of up to 688 m³/h.

Carbon steel gears and dual ball bearings also contribute to the mechanism’s durability. The device’s rated service life is as high as 67,000 operating hours.

Stable and Compact Mounting System

The mounting clamp has also been redesigned. The compact, metal construction takes up very little space, which is particularly important inside a grow tent.

The vise-like mounting allows the fan to be securely attached to a structural post. The CLOUDRAY S9 can operate in both vertical and horizontal positions, making it easier to adjust its orientation to fit the available space.

Adapted to greenhouse conditions

The fan has an IP54 protection rating, making it suitable for long-term operation in environments with high humidity and temperature.

The operating temperature range is 0 to 60°C, while the recommended relative humidity during operation is between 35% and 85%.

The device also meets ETL safety requirements —certificate no. 5027708.

Integration with the UIS™ Platform

The CLOUDRAY S9 is part of the AC Infinity UIS™ ecosystem, which allows you to connect compatible devices and create an automated growing environment.

Once the fan is connected to a compatible UIS controller, you gain access to additional features such as app-based control via Wi-Fi, operating schedules, timers, responses to specific climate parameters, and more advanced automation scenarios.

This allows the fan to become part of a larger, smart system for controlling conditions within the growing space.
