Take complete control of your indoor microclimate with the AC Infinity Cloudline Pro T4. This commercial-grade, 4-inch smart inline duct fan system is engineered specifically for growers who require precise automation over their cultivation spaces. Combining quiet operation with an intelligent environmental controller, it effortlessly extracts heat and humidity to maintain the perfect growing environment for higher yields.

Advanced Climate Automation with VPD Control

The standout feature of the Cloudline Pro T Series is the included intelligent smart controller. Operating as the brain of your grow room, this central unit allows you to program dynamic triggers based on temperature, relative humidity, and VPD (Vapour Pressure Deficit).

Instead of manually guessing and adjusting fan speeds, the system continuously calculates environmental stress. It automatically ramps its energy-efficient EC motor up or down to hold your exact target microclimate.

Quiet, Powerful, and Built to Last

Whisper-Quiet Operation: Generating a capable 205 CFM of airflow, the Pro T4 operates at a whisper-quiet noise rating of just 28 dBA—remaining practically silent outside your grow tent.
PWM-Controlled EC Motor: The advanced Electronically Commutated (EC) motor uses up to 50% less energy than standard AC fans and delivers smooth speed transitions.
Heavy-Duty Construction: Built for the demanding, high-moisture environments of hydroponic setups. The IP44-rated housing is dust and splash-resistant, featuring dual ball bearings rated for an exceptional 67,000 hours of continuous runtime.

How to Setup & Use the Cloudline Pro T4 System

1. Mount the Fan and Smart Controller

Identify the airflow direction using the directional arrow embossed on the plastic fan body.
Secure the mounting base horizontally or vertically to your grow room frame or wall using the included hardware.
Mount the smart controller outside your grow tent or on a wall at eye level using the included bracket or magnetic back.

2. Position the Sensor Probe

Plug the thermal climate probe into the bottom port of the smart controller.
Route the cord into your grow space and hang the sensor head directly at plant canopy level.
Keep the probe shaded from direct grow light rays and away from humidifiers to ensure accurate ambient readings.

3. Connect and Power On

Plug the fan's data cable directly into Port 1 on the smart controller.
Connect the fan's main power adapter to a standard mains wall outlet.
The controller will power on, automatically detect the Cloudline Pro T4, and display real-time climate data.

4. Configure Your VPD and Climate Triggers

Open the controller menu or link it to your smartphone app via Bluetooth or WiFi.
Set your desired VPD target or maximum temperature/humidity thresholds for your current growth stage.
Program the fan's "Buffer" settings to allow it to smoothly ramp through speeds 1–10, preventing abrupt microclimate swings.

Care and Easy Maintenance Tips

Tool-Free Assembly: Unclip the central motor box from the mounting flanges to slide out the impeller housing. This allows for effortless dusting between harvest cycles without taking down your flexible ducting.
Keep Connections Dry: While the probe and fan casing are highly moisture-resistant, ensure the data link ports and power supply blocks remain completely dry.
