Whisper-Quiet Grow Room Ventilation in an Affordable Value Package
Optimise your cultivation climate with the AC Infinity Cloudline A4 Lite EC Fan. Engineered to deliver the same premium build quality and advanced internal technology as the flagship Cloudline series, this 4-inch inline duct fan offers a cost-effective ventilation solution without sacrificing performance. Delivering a powerful 165 CFM airflow at a whisper-quiet noise level of just 29 dBA, it is the perfect choice for extracting odours, cooling grow tents, and transferring air across enclosed spaces.

At the heart of the Cloudline A4 Lite is a cutting-edge, PWM-controlled EC motor that ensures maximum energy efficiency and ultra-smooth operation at low RPMs without generating disruptive hums. Its advanced mixed-flow design uses a stator blade to maintain exceptional static pressure. This allows the fan to move air efficiently even when connected to restrictive carbon filters or long runs of ducting. Built to last, the IP44-rated dust and splash-resistant housing features dual ball bearings rated for 67,000 hours of continuous use.

How to Use the Cloudline A4 Lite 4-Inch Fan:

Follow these straightforward steps to safely mount, wire, and control your new inline extractor fan.

1. Flexible Mounting Setup

Determine your airflow direction by looking at the directional arrow printed on the fan housing.
Secure the lightweight plastic mounting base horizontally or vertically to your grow tent frame or wall support using the included hardware.
Tip: Because it utilizes dual ball bearings, you can mount this unit safely in any orientation or angle.

2. Ducting and Filtration Connection

Slide your standard 4-inch flexible ducting or a matching 4-inch carbon filter directly over the fan's intake or exhaust flanges.
Secure the ducting tightly using metal worm clamps to prevent any stale air or unscrubbed odours from leaking into your room.

3. Power and Speed Control

Plug the inline fan's power adapter into a standard mains outlet.
Connect the included wired 10-speed controller to the fan body to easily adjust your airflow and noise levels across ten precise speeds.
The controller features built-in backup memory, meaning it will automatically resume your last speed setting if power is temporarily disconnected.

4. Optional Smart Ecosystem Upgrade

To unlock remote monitoring and climate automation, disconnect the basic speed controller.
Use a UIS adapter link to plug the Cloudline A4 Lite directly into an advanced central hub controller.
This connection allows your temperature, humidity, and VPD thresholds to automatically spin the fan up or down.

Care and Easy Maintenance Tips:

Detachable Design: You don't need to take down your entire ducting assembly to clean the fan. Simply unscrew the mounting clips to release the central motor box containing the impeller blades for effortless dusting between harvests.
Keep Clear of Liquids: While the IP44 rating protects against high humidity and environmental splashing, the fan must never be exposed to direct water sprays or running liquid.
