Who This Is For
- You are upgrading to an 8-inch fan because your current 6-inch setup can't clear heat fast enough in mid-summer.
- You are installing a mixed-flow system because static pressure from long duct runs is killing your old fan's intake.
What We Found
- The way the motor box pops out without duct removal makes it the easiest fan to clean in the shop.
- Even without a smart controller, the lowest manual settings are exceptionally quiet for night cycles.
- The mixed-flow design is better at handling long duct runs than any standard axial fan we have tested.
What Users Say
- Buyers say they stopped worrying about noise complaints after the EC motor dropped their decibel levels.
- Users who added the smart controller say they finally achieved stable temps by automating the fan speed.
- Operators report that the IP44 rating saved their equipment during a humidity spike that caused condensation.

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.
