AC Infinity CLOUDLINE T4, Quiet Inline Fan System with Temperature Humidity VPD Controller, 100mm

Product detailed description

Smart climate control even in a small tent

AC Infinity CLOUDLINE T4 is an inline fan for 100 mm ducting, which, unlike the Value and S models, comes with a smart controller in the box - the same performance as the CLOUDLINE S4 (348 m3/h, 205 CFM), plus automatic climate-based control. It is suitable for smaller tents and boxes for germination and seedlings, where you want precise environmental control from the start without buying an additional controller.

What is in the box

The package contains the CLOUDLINE T4 fan, the CONTROLLER 69 PRO smart controller with display and sensor probe (3.66 m cable) for measuring temperature and humidity, and a power cable with a US plug. The fan control cable plugs directly into the controller's UIS port - CLOUDLINE is UIS-native and does not need any adapter.

VPD-based control

Controller 69 Pro can set triggers based on temperature, humidity and VPD (Vapor Pressure Deficit), together with dynamic fan speeds that respond to current conditions. You can also set a minimum speed for constant circulation and use timer, cycle or schedule modes. Via WiFi or Bluetooth, the controller connects to the AC Infinity app, where historical graphs, data export, remote control and notifications are available. Controller 69 Pro independently controls up to four UIS platform devices - alongside the T4, you can connect another CLOUDLINE, a CLOUDRAY circulation fan or IONBOARD LED lighting.

Motor and construction

The EC motor controlled by PWM ensures quiet operation (28 dBA) even at low speeds. Static pressure 223 Pa, dual ball bearings with a service life of 67,000 hours, horizontal and vertical mounting, IP44 protection.

Frequently asked questions

Does a smart controller make sense for a small 100 mm tent?
The T4 has the same performance as the S4 (348 m3/h), and it also adds the Controller 69 Pro straight in the box - temperature, humidity and VPD control plus app control, without having to buy the controller separately. It is suitable if you want precise and automatic climate control in a small tent (germination, seedlings) without manual speed switching.

How does VPD control work?
Controller 69 Pro calculates VPD from the measured temperature and humidity (3.66 m probe) and dynamically changes the fan speed according to the set triggers; you can also set a minimum speed for continuous circulation.

What exactly is included in the CLOUDLINE T4 package?
The CLOUDLINE T4 fan, the CONTROLLER 69 PRO smart controller with display, sensor probe (3.66 m) and power cable. There is no need to buy the controller separately.
