AC Infinity CLOUDLINE PRO T4, Quiet Inline Fan with Temperature & Humidity Control, 100mm

AC Infinity CLOUDLINE PRO T4-T8 for responsive extraction and climate control

The AC Infinity CLOUDLINE PRO T4-T8 series combines a variable-speed EC inline fan with the smart CONTROLLER 69 PRO. The range includes the T4, T6 and T8 with 100, 150 and 200 mm duct connections respectively. It suits both new and experienced indoor growers who want automatic control of temperature, humidity and air exchange in a grow tent or grow room. Depending on the model, airflow ranges from approximately 348 to 1,371 m³/h.

Automatic control using temperature, humidity and VPD

The supplied sensor measures temperature and humidity, while the CONTROLLER 69 PRO can also use VPD as part of its programming. VPD, or vapour pressure deficit, provides a useful indication of the relationship between temperature and humidity around the plants. Rather than simply switching the fan on and off, the controller can apply dynamic output levels and maintain a defined minimum speed. Timer, cycle and schedule modes provide further options for adapting ventilation to different times of day and growth stages.

EC motor and mixed-flow design for stable extraction

The PWM-controlled EC motor runs smoothly even at reduced speeds. Its mixed-flow construction with stator blades helps maintain airflow against increased static pressure caused by filters, ducting and bends. Dual ball bearings allow horizontal or vertical installation, while the motor and impeller assembly can be removed from the mounted frame for easier cleaning. An IP44 rating provides protection against dust ingress and splashing water.

Three sizes for different ventilation systems

The T4 uses a 100 mm connection and delivers approximately 348 m³/h, the T6 uses 150 mm and reaches 683 m³/h, while the T8 uses 200 mm and reaches 1,371 m³/h. The appropriate size depends not only on room volume but also on carbon filters, duct length and other sources of airflow resistance. You can compare further models in the EC duct fan range. For a complete extraction setup, combine the fan with a suitable carbon filter and correctly sized ventilation ducting.

WiFi app control and UIS integration

The CONTROLLER 69 PRO connects to the AC Infinity app via WiFi. From the app you can adjust programs, configure notifications, review historical climate charts and export measurement data as CSV files. The controller supports up to four UIS devices, allowing the CLOUDLINE fan and other compatible equipment to form part of a coordinated environmental control system.
