Description

Designed to ventilate hydroponic grow rooms, transfer heating and cooling, cool AV cabinets, and remove odors. Features dynamic temperature and humidity programming, timers, grow cycles, and minimum speed settings.

Remote WiFi access via the AC Infinity app unlocks advanced programs, climate data charts, and automation controls. The mixed-flow design combined with a PWM-controlled EC motor provides extremely quiet and energy-efficient performance.

The removable motor housing allows easy maintenance. Part of the UIS™ ecosystem for integrated climate, airflow, and lighting control.

Intelligent Controller

The CONTROLLER 69 PRO provides advanced programming beyond basic triggers for temperature, humidity, and VPD. Dynamic fan speeds respond to climate changes, with the option to set a minimum constant speed. Timer, cycle, and schedule modes add customized operation.

Through the AC Infinity app, users can remotely adjust settings, create automation rules, receive alerts, check historical climate charts, and export CSV logs. The controller supports up to four UIS devices including CLOUDLINE, CLOUDRAY, and IONFRAME products, and can connect to external grow lights and output devices via adapters.

Quiet and Energy-Efficient Design

Unlike AC-motor duct fans, the PWM-controlled EC motor runs smoothly even at low RPM without noise or excess heat. The mixed-flow structure with stator blade and dual hydrodynamic rings ensures strong airflow and high static pressure even in restricted environments.

Dual ball bearings provide long lifespan and allow both horizontal and vertical mounting. Rated IP44 for dust and splash resistance.

Applications

Ideal for cooling AV rooms, cabinets, racks, hydroponic grow tents, bathrooms, attics, and other ventilation setups requiring quiet and smart airflow control.
