Unlike basic fans, its stator blade and hydrodynamic wind circles maintain performance even in high-resistance ducting. Dual ball bearings rated for 67,000 hours and an IP44 rating guarantee durability and versatile mounting options, making it a reliable choice for demanding indoor environments. This fan integrates seamlessly with the UIS platform for smart environmental control, offering precise programming for optimal conditions. **Ideal for Indian Indoor Gardening & AV Cooling** — This fan is perfect for Indian growers needing robust ventilation for hydroponic setups or AV closet cooling. Its 12-inch duct size (approx. 305mm) fits standard ducting, and the 1604 CFM airflow is suitable for most grow tents. While effective for general air circulation, users with extremely high-heat AV racks or sensitive grow environments might consider models with higher CFM or EC controllers offering finer granular speed adjustments. For those seeking basic room ventilation without complex programming, simpler exhaust fans may suffice, but the CLOUDLINE PRO S12 offers advanced control and efficiency. ## How to use 1. Securely mount the fan within your ducting system using appropriate clamps or flanges. Ensure the fan is oriented correctly for airflow direction and that the mounting allows for vibration dampening. The dual ball bearings permit mounting in any direction. — Mount the Fan 2. Attach the 12-inch ducting to both ends of the fan. Connect the wired speed controller to the fan's motor and plug the controller into a compatible 220-240V power source. Ensure all connections are airtight. — Connect Ducting and Controller 3. Use the 10-speed controller to set the desired airflow. For advanced automation, connect the controller to the UIS platform and program custom schedules based on time or environmental triggers for optimal ventilation. — Set Fan Speed and Program 4. Periodically check airflow and listen for unusual noises. Detach the motor box for cleaning the impeller and blades as needed. The dual ball bearings are rated for 67,000 hours of operation. — Monitor and Maintain ## Product details | Field | Value | |---|---| | Recommended Use | Ventilating grow rooms, boosting HVAC, cooling AV closets, air circulation, odor exhaust | | Indoor/Outdoor Usage | Indoor | | Operating Temperature | Not specified, but IP44 rated for harsh environments | | Cost per CFM | 1604 CFM at ₹78,966 — ₹49.23 per CFM | | Cost per Hour (Est. at 250W) | At 250W, ₹316 per watt per hour, assuming ₹10/kWh electricity rate. | | Contraindications | Not suitable for outdoor use; ensure proper voltage compatibility (220-240V) for Indian mains. | | Allergens / Common Irritants | N/A | | Brand | AC Infinity | | Model Name | CLOUDLINE S12 | | Part Number | AI-CLS12 | | Duct Size | 12 inches (305 mm) | | Dimensions (Fan Body) | 14.9 x 17.7 x 14.1 inches (37.8 x 45 x 35.8 cm) | | Airflow Capacity | 1604 CFM (2725 m³/h) | | Noise Level | 62 dBA | | Motor Type | EC Motor with PWM Control | | Number of Speeds | 10 (via controller) | | Bearings | Dual Ball (67,000 hours) | | Material | Metal Housing, Black Finish | | IP Rating | IP44 | | Power Source | AC (220-240V compatible) | | Wattage | 250 W | | Cord Length | 144 inches (3.66 m) | | Mounting Type | Downrod Mount / Duct Mount | | Control Method | Wired Controller, UIS Platform Compatible | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### What fan size do I need for my grow tent? For grow tents, match the fan's airflow (CFM or m³/h) to your tent volume. A common rule is to exchange the tent's air volume several times per minute. For the AC Infinity CLOUDLINE PRO S12, its 1604 CFM is suitable for tents up to approximately 10x10 ft (2725 m³/h for 77 m³ tent volume, ~35 air changes per hour). Consider adding capacity if running a carbon filter or lights that raise heat. Ensure the 12-inch duct diameter matches your filter and ducting. ### Will this ventilation equipment work on Indian power? Yes, the AC Infinity CLOUDLINE PRO S12 is designed for 220-240V Indian mains power. It features an AC power source type and is compatible with standard Indian electrical outlets, though a Type C/D plug adapter may be needed depending on your specific socket type. The fan's EC motor is highly energy-efficient. ### How quiet is the AC Infinity CLOUDLINE PRO S12 fan? The fan operates at a noise level of 62 dBA, which is comparable to normal conversation. Its PWM-controlled EC motor is specifically designed for quiet and energy-efficient performance, minimizing motor noise even at extremely low RPM speeds, making it suitable for noise-sensitive indoor environments. ### Can I control the fan speed remotely or program it? Yes, the CLOUDLINE PRO S12 includes a wired 10-speed controller for manual adjustments.
