Who This Is For
- You are upgrading your ventilation because your current fan's noise is becoming a distraction in the next room.
- You are switching to a mixed-flow fan because your old axial fan cannot push enough air through your carbon filter.
- You are building a UIS ecosystem because you want to eventually automate your climate based on actual probe data.
What We Found
- This fan stays remarkably quiet until you crank it past level seven, making it perfect for stealthy setups.
- The UIS ecosystem is the real win here, as it lets you link all your environment tech to one smart controller.
What Users Say
- Users who clean their gear regularly say the detachable impeller saves them an hour of scrubbing every few months.
- Buyers who transitioned from single-speed fans say the 10-speed dial finally let them dial in the perfect humidity.

FAQs
What's the difference between the Cloudline Lite and the regular Cloudline T-series?
The Lite series offers the same core performance and quality in a more affordable package. The main difference is that it includes a manual 10-speed controller instead of the smart thermostat controller that comes with the T-series models.
Can I use this fan for both intake and exhaust?
Yes, its mixed-flow design is highly efficient for both bringing fresh air into your space and exhausting hot, stale air out, making it a versatile choice for any ventilation setup.
How quiet is the Cloudline Lite A4?
It's designed for quiet operation, producing only 29 dBA at its peak. This makes it ideal for home and residential environments where low noise is a priority.
Can I upgrade the controller later?
Absolutely. This fan is fully compatible with advanced controllers like the AC Infinity Smart Controller 69 Pro, allowing you to add smart features and environmental automation to your setup whenever you're ready.
What size ducting and accessories should I use?
The Cloudline Lite A4 is designed for 4-inch ducting. For the best performance and noise reduction, we recommend using it with a compatible 4" Duct Silencer and a high-quality 4" carbon filter.
