CLOUDLINE T4 – 4-Inch Smart Inline Duct Fan with CONTROLLER 69 PRO
AC Infinity
Quietly and intelligently ventilate your grow space, AV closet, or any controlled environment with the AC Infinity CLOUDLINE T4. This 100mm (4-inch) smart inline duct fan is engineered for high-performance airflow in hydroponic grow rooms, heating and cooling transfer, odor exhaust, and equipment cooling—delivering reliable, energy-efficient circulation even under high static pressure.
At its core is a mixed-flow design paired with a PWM-controlled EC motor, producing smooth, quiet operation at just 26 dBA while moving up to 226 CFM of air. Unlike traditional AC-motor fans that generate excess noise and heat at low speeds, this EC motor runs efficiently across its full range. Dual ball bearings rated for 67,000 hours allow the unit to be mounted in any orientation, and the IP44 rating ensures strong resistance to dust and moisture in demanding environments. The motor housing can be easily detached from the mounting frame for quick cleaning and maintenance.
Complete control comes from the included CONTROLLER 69 PRO. Set dynamic temperature, humidity, and VPD triggers that automatically adjust fan speed in response to climate changes. Establish a minimum continuous speed that only ramps up when conditions demand it. Timer, cycle, and schedule modes provide flexible on-demand operation. Connect via WiFi to the AC Infinity app for full remote access—view live climate data, create advanced automations, receive notifications, review historical charts, and export CSV logs from anywhere.
As part of the UIS™ platform, the CONTROLLER 69 PRO can manage up to four UIS devices (including other CLOUDLINE, CLOUDRAY, and IONFRAME products) and integrate with select non-UIS grow lights or outlet devices using compatible adapters—creating a unified, intelligent grow environment.
Compact yet powerful, the unit measures 17.5 × 30.2 × 18.8 centimeters and fits seamlessly into 100mm ducting systems. Whether you’re optimizing a grow tent, cooling sensitive AV equipment, exhausting an attic or bathroom, or circulating fresh air in a closed space, the CLOUDLINE T4 delivers professional-grade performance with whisper-quiet operation and smart automation.
