AC Infinity Cloudline Lite A-Series Inline EC Fans with Speed Controller

AC Infinity CLOUDLINE LITE A-Series Inline Fans

The AC Infinity CLOUDLINE LITE A-Series combines quiet EC-motor technology, adjustable airflow and dependable CLOUDLINE construction in a straightforward, value-focused extraction fan.

Available in 4-inch, 6-inch and 8-inch sizes, the range covers everything from compact grow tents to larger indoor gardens. Simply select the duct size that matches your ventilation system using the options above.

Every model includes a wired ten-speed controller, allowing you to balance airflow, noise and energy consumption without being limited to a basic on-or-off switch. Run the fan gently when conditions are stable, then increase extraction when heat and humidity start plotting against you.

Quiet, Adjustable Grow-Tent Extraction

Indoor plants require a regular supply of fresh air, while grow lights and transpiration continually add heat and moisture to the environment. A properly sized CLOUDLINE LITE fan removes warm, humid and stale air, helping to create more stable growing conditions.

Pair the fan with a matching carbon filter to help remove unwanted odours from extracted air. Its mixed-flow design and EC motor maintain useful airflow against the resistance created by filters and ducting.

The range provides three airflow capacities:

• CLOUDLINE A4: up to 165 CFM / approximately 280m³/h
• CLOUDLINE A6: up to 352 CFM / approximately 598m³/h
• CLOUDLINE A8: up to 724 CFM / approximately 1,230m³/h

Published airflow figures represent unrestricted maximum performance. Carbon filters, silencers, duct bends and longer duct runs will reduce the airflow achieved after installation.

Why Choose a CLOUDLINE LITE A-Series Fan?

• Three duct sizes available – choose 4, 6 or 8 inches to match your ventilation system
• Wired ten-speed controller included – adjust extraction without buying another basic controller
• Energy-efficient EC motor – provides smooth speed control and efficient continuous operation
• Mixed-flow impeller – maintains useful airflow through carbon filters and ducting
• Quiet operation – designed to reduce unnecessary motor and vibration noise
• Backup memory – restores the previous speed setting following a power interruption
• Dual-ball bearings – support horizontal or vertical installation
• Removable motor assembly – provides easier access for cleaning and maintenance
• IP44-rated construction – resistant to dust and splashing water
• Smart-controller compatible – upgrade to selected AC Infinity environmental controllers

Ten-Speed EC Fan Controller Included

Every CLOUDLINE LITE A-Series fan includes a wired controller with ten speed levels. This provides much finer control than a fixed-speed extraction fan and makes it easier to respond to seasonal and environmental changes.

The EC motor uses pulse-width modulation to provide smooth low-speed control without generating the intrusive motor hum often associated with less advanced fan-control methods.

Running at a lower speed can reduce noise and energy consumption when maximum extraction is unnecessary. Higher settings provide additional airflow during warmer conditions or periods of increased humidity.

Compatible with AC Infinity Smart Controllers

The included controller provides manual ten-speed adjustment, but the fan can also be upgraded with a compatible AC Infinity smart controller.

Depending on the controller selected, this can add:

• Temperature-based fan-speed control
• Humidity-based extraction
• VPD monitoring and programming
• Timers, schedules and cycles
• Minimum and maximum speed settings
• WiFi and Bluetooth app access
• Environmental alerts and historical charts
• AI-powered environmental adjustment

Compatibility and connection requirements vary between controllers. Additional UIS cables or adaptors may be required and are sold separately.

Choose the Correct CLOUDLINE LITE Size

Selecting the correct fan depends on grow-space volume, lighting heat, carbon-filter resistance, duct length and the number of bends in the system.

The A4 is the quietest and most compact option. It suits small tents and short 4-inch ventilation systems.

The A6 provides a strong balance of airflow, noise and power consumption for medium grow tents. Its 6-inch connection also provides greater capacity when used with a carbon filter.

The A8 is designed for larger grow tents, grow rooms and higher-resistance extraction systems requiring substantially more airflow.

If your calculated airflow requirement sits close to a fan’s maximum rating, choose the larger model and run it at a reduced speed. This provides additional capacity for filtration and duct resistance while often producing less noise than a smaller fan running flat out.

Frequently Asked Questions

Which CLOUDLINE LITE size should I choose?
Choose the duct size that matches your filter and ventilation system, then check that the airflow provides enough capacity for the grow-space volume, lighting heat and duct resistance. When requirements sit close to the maximum rating, choose the larger model and reduce its speed.

Does every size include a controller?
Yes. The A4, A6 and A8 each include a wired controller with ten speed settings and backup memory.

Can these fans be used with carbon filters?
Yes. Pair the selected fan with a carbon filter of the same duct diameter and a suitable airflow rating.

Will a carbon filter reduce the airflow?
Yes. Carbon filters, silencers, duct bends and long duct runs all create resistance and reduce the final installed airflow.

Can the fans be connected to a smart controller?
Yes. The CLOUDLINE LITE A-Series supports selected AC Infinity smart controllers. Connection requirements vary, so an additional UIS cable or adaptor may be required.

Can they be mounted vertically?
Yes. Dual-ball bearings allow horizontal or vertical installation.
