FAQs

What's the main difference between the Cloudline S-series and T-series fans?+

The S-series, like this Cloudline S8, includes a manual 8-speed fan controller for simple adjustments. The Cloudline T-series comes with an advanced smart controller that allows for temperature and humidity programming, timers, and automation.

Is this fan loud?+

No, the Cloudline S8 is designed for quiet operation. It uses a PWM-controlled EC motor which is significantly quieter than traditional AC motors, making it ideal for residential use.

Can I use this fan for applications other than grow tents?+

Absolutely. This fan is excellent for ventilating AV equipment closets, workshops, basements, or any space that requires consistent air circulation or heat and odor removal.

How do I install the Cloudline S8?+

Installation is straightforward. The fan can be mounted in any orientation (horizontally or vertically) using the included hardware. It's designed to fit standard 8-inch ducting, which can be secured with the provided clamps. For more details, check out our guide on AC Infinity air filter kits.

What size carbon filter should I pair with this fan?+

For optimal performance, you should pair the Cloudline S8 with an 8-inch carbon filter, such as the AC Infinity 8" Duct Premium Carbon Filter. This ensures a perfect fit and matching airflow capacity.

Do I need anything else to complete my ventilation setup?+

To create a complete system, you'll need ducting. We recommend the AC Infinity 8" Flexible Four-Layer Ducting for a durable, light-proof connection. You might also consider an 8" Duct Silencer to further reduce noise.
