Powerful Airflow Without the Excess Noise

The AC Infinity CLOUDLINE S6 150mm Inline Fan is engineered for growers who want serious ventilation performance without the excessive noise produced by traditional inline fans.

With airflow of up to 402 CFM and an operating noise level of just 32 dBA, the CLOUDLINE S6 is an excellent choice for maintaining fresh air exchange, controlling heat and managing humidity in indoor growing environments.

Its advanced mixed-flow design helps maintain strong airflow even when connected to ducting, bends and carbon filtration systems.

Premium EC Motor Technology

At the heart of the CLOUDLINE S6 is an energy-efficient EC motor controlled using PWM technology.

Unlike conventional AC motors, the EC motor allows the fan to operate smoothly at very low speeds while reducing unnecessary electrical consumption, heat and motor noise.

Maximum power draw is only 70W, with average power consumption considerably lower during normal operation.

10-Speed Controller Included

The included wired controller gives you 10 individual fan speed settings, allowing airflow to be adjusted to suit the size of your grow tent, environmental conditions and extraction requirements.

Running a fan continuously at the correct speed can help maintain a more stable indoor growing environment without constantly switching ventilation equipment on and off.

The controller also remembers its previous speed setting if power is interrupted.

AC Infinity UIS Compatible

The CLOUDLINE S6 can also be integrated into the AC Infinity UIS ecosystem using a compatible UIS environmental controller.

This gives growers the option to upgrade their ventilation system and integrate fan operation with other compatible AC Infinity environmental equipment.

Built for Grow Room Conditions

The CLOUDLINE S6 features an IP44-rated housing, providing increased resistance to dust and moisture commonly encountered in grow rooms and indoor horticultural environments.

Dual ball bearings are rated for approximately 67,000 hours of operation, while the fan can be installed horizontally or vertically depending on your ventilation layout.

The motor and impeller assembly can also be removed from the mounting frame, making routine cleaning and maintenance considerably easier.

Ideal For

• Hydroponic grow rooms
• Indoor gardens
• Grow tents
• Carbon filter extraction systems
• Heat removal
• Humidity management
• Fresh air exchange
• Ventilation systems
• Climate-controlled plant rooms
• Propagation rooms
• Equipment and cabinet cooling

Pair the CLOUDLINE S6 with 150mm ducting and a compatible 150mm carbon filter to create a powerful complete extraction system.
