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 included as standard - the same performance as CLOUDLINE S4 (348 m3/h, 205 CFM), plus automatic climate-based control. It is suitable for smaller tents and propagation boxes where you want precise environmental control from the start without having to purchase an additional controller.

What is included

The package contains the CLOUDLINE T4 fan, a 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 connects directly to the controller's UIS port - CLOUDLINE is UIS-native and does not require an 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. A minimum speed can also be set for constant circulation, and timer, cycle or schedule modes can be used. Via WiFi or Bluetooth, the controller connects to the AC Infinity app, which provides historical graphs, data export, remote control and notifications. Controller 69 Pro independently controls up to four devices on the UIS platform - alongside T4, you can connect another CLOUDLINE, a CLOUDRAY circulation fan or IONBOARD LED lighting.

Motor and construction

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

Frequently asked questions

Is a smart controller worthwhile for a small 100 mm tent?
T4 has the same performance as S4 (348 m3/h), while also including Controller 69 Pro as standard - control based on temperature, humidity and VPD, as well as app control, without having to purchase the controller separately. It is suitable if you want precise and automatic climate control in a small tent for propagation and seedlings, without manually switching speeds.

How does VPD-based 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; a minimum speed can also be set for continuous circulation.

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