AC Infinity CLOUDLINE PRO S4-12 with Speed Controller

Quiet and Precisely Adjustable Ventilation for Grow Tents

The CLOUDLINE PRO S-Series by AC Infinity – available in sizes S4, S6, S8, S10, and S12 – offers powerful yet whisper-quiet airflow for your grow environment. With its 10-speed analog fan controller, you can fine-tune airflow to meet the specific needs of your tent. The mixed-flow design ensures consistent pressure even across long ducting or when paired with carbon filters – ideal for professional and home growers alike.

Each model is equipped with a PWM-controlled EC motor, combining energy efficiency with low noise and minimal heat generation. Airflow performance varies by model – from compact setups with the S4 to high-capacity air exchange with the S12. Thanks to the optimized fan housing and internal structure, noise levels and power consumption remain impressively low across the entire series.

Reliable Air Circulation – Even at Low Speeds

Even at reduced fan speeds, the S-Series ensures consistent ventilation. Its design includes stator blades and dual hydrodynamic wind circles for balanced pressure and smooth airflow. The dual ball bearing motor can be mounted in any direction – horizontally or vertically – making it highly adaptable for a wide range of grow setups.

With its IP44 rating, the housing is protected against dust and splashes – ideal for humid or demanding environments. The removable casing allows for easy cleaning and maintenance without tools or disassembly hassles.

Optional Smart Control & Backup Memory for Extra Security

The CLOUDLINE PRO S-Series is compatible with AC Infinity’s UIS™ platform. When paired with an optional UIS controller, you unlock advanced climate automation features – including temperature- or humidity-triggered airflow, schedules, and grow cycles. Remote control and app integration are also possible when using compatible UIS hardware.

Built-in backup memory ensures that your last speed setting is preserved in case of a power outage – so your airflow resumes exactly where you left off, with no need to reset anything manually.

Recommended Use per Model

• S4: for small tents up to approx. 90 × 60 × 180 cm or as an intake fan
• S6: for mid-sized setups with ducting and carbon filters
• S8: for larger grow tents or parallel grow environments
• S10: for expanded duct systems or multi-room installations
• S12: for professional operations and high-volume ventilation
