## Overview

The AC Infinity CLOUDLINE S6 is a premium 6-inch inline duct fan engineered for silent, efficient ventilation. Featuring a high-performance mixed-flow EC motor with 8-speed PWM control, it delivers 402 CFM airflow at just 32 dBA noise. Designed for grow tents, AV racks, and climate control, it includes durable double ball bearings, IP44 rating, and a complete installation kit, making it the go-to choice for professionals seeking precise, energy-efficient air circulation.

## Description

Inline Channel Fan The channel fan system is designed to cool AV equipment rooms and closets in a quiet way and to create air circulation and ventilation. Features a built-in speed control that uses PWM technology. Includes a mix-flow design and an EC motor for quiet and high static pressure performance. The engine box containing the pump wheel and blades of the fan can be removed for easy cleaning and maintenance. Complete kit includes a channel fan unit, an inline speed controller, installation manual (English language not guaranteed). All necessary mounting hardware and a corded power adapter (UK 3-pin 220-240V/AC wall plug - Type G) to power the device through a standard socket. This product is part of the UIS platform with growing devices and smart controllers designed to be integrated with each other to achieve your ideal environment. Precise speed control. With the built-in speed controller, you can set the fan speed to get optimal noise level and airflow in different environments. Unlike standard AC-powered channel fans that suppress the voltage to control fan speeds, this channel fan has a DC motor that is precisely controlled with PWM (Pulse Wide Modulation). This technology allows the motor to run smoothly at low speeds without generating engine noise and heat. Eight speed options are available with switches and backup memory. This S6 model can be connected to the CLOUDLINE T6 smart controller to share the same programming and power source. Silent and energy-efficient design. The inline booster fan features a mix-flow design with a stator blade and double hydrodynamic wind circles. This gives it a high static pressure, allowing it to deliver airflow in applications where air movement is restricted. The motor has double ball bearings with a life of 67,000 hours, which allows the channel fan to be mounted in any direction. The device is IP44 rated to be highly resistant to dust and liquids.

Review: The brand is one of the better manufacturers selling to the general public and the vendor was very supportive and provided prompt service. I would buy from them again and recommend the inline fan without hesitation. It’s quiet at lower settings and works without issue.
Review: Good quality. Very quiet.

*by D***D on 21 October 2025*

This inline fan works great — super quiet and powerful, exactly what I needed to improve airflow in a small space. It moves a lot of air without the loud hum you get from cheaper fans. Installation took a bit of fiddling to get everything sealed properly, but once it was set up, it ran smoothly. Really happy with the quality and performance.
