AC Infinity CLOUDLINE T PRO Inline Fan with Controller 69 PRO – Smart Ventilation & Environmental Control

The AC Infinity CLOUDLINE T PRO Inline Fan with Controller 69 PRO is a premium smart ventilation system designed to provide quiet, energy-efficient airflow and automated environmental control for grow tents, hydroponic rooms, indoor gardens, greenhouses, HVAC applications, and other ventilation systems.

Powered by an advanced PWM-controlled EC motor, the CLOUDLINE T PRO delivers strong airflow with reduced operating noise and energy consumption. The included AC Infinity Controller 69 PRO adds intelligent control based on temperature, humidity, VPD, timers, cycles, and schedules, while built-in Wi-Fi and Bluetooth connectivity allow remote access through the AC Infinity app.

Available in multiple duct sizes, the CLOUDLINE T PRO Series provides scalable ventilation for everything from compact grow tents to large indoor cultivation environments.

Includes AC Infinity Controller 69 PRO

The major advantage of the CLOUDLINE T PRO Series is the included Controller 69 PRO, a smart environmental controller designed to automate compatible AC Infinity UIS equipment.

The Controller 69 PRO can independently control up to four UIS devices, letting you manage multiple pieces of equipment from a single control system.

Compatible equipment can include:

• CLOUDLINE inline fans
• CLOUDRAY circulation fans
• IONFRAME grow lights
• UIS humidifiers
• Other compatible AC Infinity UIS devices
• Select third-party equipment when used with compatible UIS adapters

Each connected device can receive its own independent programming, allowing growers to create a more integrated indoor growing environment.

Automated Temperature & Humidity Control

The included temperature and humidity sensor lets the Controller 69 PRO automatically adjust fan operation based on environmental conditions.

Growers can establish high or low temperature and humidity triggers so the CLOUDLINE T PRO automatically increases or decreases airflow when conditions change.

This automation can help maintain a more consistent indoor environment without requiring constant manual fan adjustments.

VPD Monitoring & Automation

The Controller 69 PRO supports VPD-based programming, allowing compatible equipment to respond to changes in vapor pressure deficit.

VPD combines temperature and relative humidity, giving growers another way to monitor and manage the relationship between environmental conditions and plant transpiration.

The controller can use VPD triggers to automatically adjust connected equipment according to programmed targets.

Dynamic Fan Speed Control

Instead of simply switching the fan on or off, the Controller 69 PRO can dynamically adjust the CLOUDLINE T PRO's fan speed.

For example, growers can set a minimum fan speed to maintain continuous air exchange. When temperature, humidity, or VPD moves beyond the programmed range, the controller can automatically increase the fan speed.

This provides smoother environmental management than basic on/off ventilation systems.

Wi-Fi & Bluetooth App Connectivity

The Controller 69 PRO connects to the AC Infinity app via Wi-Fi or Bluetooth, giving you convenient access to the grow environment from a compatible mobile device.

Through the app, growers can:

• Remotely monitor environmental conditions
• Adjust fan speed
• Change controller settings
• Create advanced automation programs
• Set notifications and alarms
• Review historical climate data
• View temperature and humidity charts
• Monitor VPD
• Export climate data in CSV format

Wi-Fi connectivity is especially useful for growers who want to monitor their indoor environment while away from the grow space.

Timer, Cycle & Schedule Programming

In addition to environmental triggers, the Controller 69 PRO provides several time-based programming options.

These include:

• Timer Mode – Run equipment for a specified amount of time
• Cycle Mode – Alternate between programmed ON and OFF intervals
• Schedule Mode – Operate equipment at specific times of day
• Minimum and maximum levels – Restrict operating ranges
• Dynamic transitions – Gradually adjust equipment output as conditions change

These programming options allow the CLOUDLINE T PRO to adapt to different ventilation strategies throughout the day or growing cycle.

Quiet & Energy-Efficient EC Motor

The CLOUDLINE T PRO uses a premium electronically commutated EC motor controlled with PWM technology.

This allows the fan to operate smoothly across a wide range of speeds while reducing unnecessary electrical consumption, heat generation, and motor noise.

Key advantages include:

• Quiet operation
• Energy-efficient performance
• Precise speed adjustment
• Smooth low-RPM operation
• Reduced motor heat
• Reliable continuous ventilation

Advanced Mixed-Flow Design

The CLOUDLINE T PRO uses a mixed-flow fan design with stator blades and dual hydrodynamic wind circles.

This design generates high static pressure, helping the fan maintain effective airflow when other components in the ventilation system introduce resistance.

This makes it especially well suited for installations using:

• Carbon filters
• Long duct runs
• Multiple duct bends
• Air silencers
• Intake systems
• Exhaust systems
• Grow tent ventilation setups

Ideal for Carbon Filter Systems

The CLOUDLINE T PRO pairs easily with compatible AC Infinity carbon filters and flexible ducting to create a complete grow tent exhaust system.

A typical configuration may include:

Carbon Filter → CLOUDLINE T PRO Inline Fan → Flexible Ducting → Exhaust

The fan's mixed-flow design helps compensate for airflow resistance created by carbon filters and ducting.

Detachable Motor Assembly for Easier Cleaning

You can remove the motor housing, impeller, and fan blades from the mounted frame, simplifying maintenance and cleaning.

This lets you service the fan without completely dismantling the surrounding ductwork.

Routine cleaning can help maintain airflow efficiency and reliable long-term ventilation performance.

Dual Ball Bearings for Long-Term Operation

The CLOUDLINE T PRO Series features dual ball bearings rated for approximately 67,000 hours of operation.

The bearing system also lets you install the fan in either horizontal or vertical orientations, giving you more flexibility when planning grow tent or grow room ventilation.

IP44-Rated Construction

The inline fan carries an IP44 ingress-protection rating, providing resistance against dust and splashing liquids.

This helps make the CLOUDLINE T PRO suitable for demanding indoor growing and ventilation environments where humidity levels may fluctuate.

Available CLOUDLINE T PRO Sizes & Airflow

The CLOUDLINE T PRO Series is available in multiple duct sizes:

• CLOUDLINE T4 (AI-CLT4) – 4": up to 205 CFM, approximately 28 dBA
• CLOUDLINE T6 (AI-CLT6) – 6": up to 402 CFM, approximately 32 dBA
• CLOUDLINE T8 (AI-CLT8) – 8": up to 807 CFM, approximately 39 dBA
• CLOUDLINE T10 (AI-CLT10) – 10": up to 1,201 CFM, approximately 48 dBA
• CLOUDLINE T12 (AI-CLT12) – 12": up to 1,604 CFM, approximately 62 dBA

This wide range of airflow capacities makes it easier to select a fan according to grow tent volume, duct length, carbon-filter resistance, lighting heat load, and desired air-exchange rate.
