Designed for smart, quiet ventilation in hydroponic grow spaces, subfloors, attics, garages, bathrooms, AV rooms and other compact ducted ventilation systems.
- Delivers up to 348 m³/h (205 CFM) for compact and medium ventilation applications.
- Helps extract heat, humidity, stale air and odours or transfer heated and cooled air.
- Smart temperature, humidity and VPD programming with timers, cycles, schedules and minimum-speed control.
- Connects to the AC Infinity app via Wi-Fi for remote monitoring, climate data, notifications and automation.
- Mixed-flow design and PWM-controlled EC motor provide quiet, energy-efficient performance through restrictive ductwork.
- Suitable for horizontal or vertical mounting with IP44-rated construction.
Duct Size: 100 mm (4″) | Dimensions: 188 × 303 × 176 mm | Weight: Approx. 3.4 kg | Airflow: 348 m³/h (205 CFM) | Noise: 28 dBA | Bearings: Dual Ball
Product Description
The AC Infinity CLOUDLINE PRO T4 is a smart 100 mm inline duct fan designed for hydroponic and home ventilation. It can help manage heat, humidity, stale air and odours in grow tents, smaller grow rooms, subfloors, attics, garages, suitably configured bathroom exhaust systems and AV equipment spaces.
Its mixed-flow design helps maintain airflow through filters, bends and restrictive duct runs. The detachable motor box simplifies cleaning and maintenance, while the included CONTROLLER 69 PRO enables climate- and time-based automation through the UIS™ platform.
Smart Climate Control
CONTROLLER 69 PRO supports temperature, humidity and VPD triggers, dynamic fan-speed adjustment, minimum-speed operation, timers, cycles and schedules. Connect through Wi-Fi to the AC Infinity app for remote control, automation, notifications, historical climate charts and CSV data export. The controller supports up to four compatible UIS devices.
Quiet, Energy-Efficient Performance
The PWM-controlled EC motor provides quiet, energy-efficient operation across a wide speed range. Its mixed-flow design and 223 Pa static-pressure rating help maintain airflow through restrictive ductwork. Dual ball bearings support horizontal or vertical mounting and are rated for up to 67,000 hours.
