AC Infinity Cloudline PRO T4 – EC Inline Fan with 69 PRO Smart Controller

The AC Infinity Cloudline PRO T4 pairs a high-efficiency EC inline fan with the 69 PRO smart controller, giving you fully automated environmental control in one box. Monitors temperature, humidity, and VPD continuously — adjusting fan speed across 10 levels so your grow space stays dialled in without constant manual input.

What’s the difference between S and T Series?

The fans are mechanically identical. S Series includes a manual 10-speed dimmer; T Series does not. If you’re pairing with a UIS controller (which this bundle includes), the T Series is the right choice — the dimmer becomes redundant anyway.

69 PRO Controller

• Automates fan speed based on temperature, humidity, and VPD targets
• 10-speed dynamic control for stable environment management
• Independently programmable ports via the AC Infinity UIS ecosystem
• WiFi and Bluetooth connectivity — monitor and schedule via the AC Infinity app
• Expandable: add fans, humidifiers, or lighting into a single coordinated system

• High-efficiency EC motor — lower running costs than traditional AC fans
• Mixed-flow design performs under pressure with carbon filters and ducting

Why automate your ventilation?

Heat build-up, humidity swings, and inconsistent airflow are common in indoor growing — and often go unnoticed until they’ve already impacted plant health. The Cloudline PRO T Series continuously corrects these variables, stabilising VPD and reducing the risk of mould, pests, and nutrient uptake issues without you needing to intervene.
