AC Infinity Cloudline PRO S Series EC Fans

The AC Infinity Cloudline PRO Inline Fan with Speed Controller is built to deliver reliable, quiet, and efficient airflow for indoor growing environments. Designed for growers who want greater control without complexity, it provides a straightforward solution to one of the most common issues in grow rooms: unstable climate conditions.

Many growers focus on lighting and nutrients, but airflow is just as important. Without proper ventilation, heat quickly builds up, humidity becomes difficult to manage, and stale air limits CO2 availability. As a result, plants can become stressed, growth slows, and the risk of mould and disease increases. The Cloudline PRO solves this by maintaining consistent air exchange, helping to stabilise temperature, humidity, and overall air quality.

Precise Airflow With Simple Control

The Cloudline PRO comes equipped with a manual speed controller that allows you to select from 10 fan speeds. This gives you direct control over airflow, so you can respond to changing conditions throughout the grow cycle. For example, you can increase airflow during peak heat periods or reduce it during cooler phases to maintain balance.

This level of control helps prevent sudden environmental swings, which are often the cause of hidden issues such as poor transpiration rates or inconsistent VPD. By maintaining steady conditions, plants can grow more efficiently and produce better results.

Quiet, Efficient EC Motor Technology

At the core of the Cloudline PRO is a high-efficiency EC motor, designed to deliver strong airflow while keeping noise levels low. This is particularly important for indoor growers working in smaller spaces or residential environments where noise can be a concern.

Compared to traditional AC fans, EC motors use less energy while offering smoother operation and longer lifespan. This not only reduces running costs but also improves reliability over time.

Designed For Real Grow Room Conditions

The Cloudline PRO uses a mixed-flow fan design, which combines high airflow with the ability to perform under pressure. This makes it suitable for use with carbon filters, ducting, and more complex ventilation setups.

The build quality reflects AC Infinity’s focus on durability and usability. The fan housing is robust, and installation is straightforward, making it accessible for beginners while still meeting the expectations of more experienced growers.

Upgrade-Ready With Smart Control Integration

While the included controller offers simple manual operation, the Cloudline PRO is part of the AC Infinity UIS ecosystem. This means it can be upgraded with advanced controllers, such as the Controller 69 PRO, to enable automation based on temperature, humidity, and VPD.

This flexibility allows growers to start with a basic setup and scale up as their needs evolve, without replacing core equipment.
