FAQs

How loud is the Cloudline T4?+

It's designed for quiet operation, producing only 28 dBA at its highest setting, which is comparable to a soft whisper.

Can I control this fan with my phone?+

This model includes the standard smart controller. For full app control via Bluetooth or Wi-Fi, you would need to upgrade to a controller like the Smart Controller 69 Pro.

What is the benefit of the mixed-flow design?+

The mixed-flow design combines features of axial and centrifugal fans, allowing it to maintain strong airflow (205 CFM) even when pushing air through long ducting or a carbon filter where static pressure is high. This ensures your ventilation is always effective.

What other equipment do I need to install this fan?+

The kit is quite comprehensive. You will need 4" ducting to connect it to your intake or exhaust ports. We recommend the AC Infinity Flexible Four-Layer Ducting for a perfect fit and durability.
