## Overview

The AC Infinity CLOUDLINE S8 PRO is a high-performance 8-inch inline duct fan designed for hydroponic grow rooms, AV closets, and HVAC boosting. It delivers 807 CFM airflow at an ultra-quiet 39 dBA noise level, powered by a PWM-controlled EC motor with 10-speed precision control. Built tough with IP44 rating and dual ball bearings, it integrates seamlessly with UIS smart controllers for automated climate management.

## Description

Product DescriptionA smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. It is built with a PWM-controlled EC motor for quiet and energy-efficient performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Includes a smart controller with dynamic climate and time-based programming and can connect to multiple UIS devices. This product is a part of the UIS platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.Precise Speed ControllerThe speed controller enables you to set the duct fan’s speed between ten speed levels to optimal noise and airflow levels in various environments. The precise airflow control is supported by the inline fan’s cutting-edge EC motor that is precisely controlled using PWM (Pulse Width Modulation). This enables it to run smoothly at extremely low RPM speeds without generating motor noise. Also features backup memory that retains the last speed setting whenever power is cut off from the controller.Quiet and Energy Efficient DesignThis duct fan uses a mixed-flow design using a stator blade and dual hydrodynamic wind circles, enabling it to deliver airflow even in applications where air movement is restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids and performs well even in harsh environments.

## Questions & Answers

**Q: We purchased the fan it is only 2 months old.  Why does it turn off constantly even as the light remains on?**
A: Might be defective or you have it on the wrong settings. Try unplugging it and if it continues to to the same then it might be defective

**Q: Can this fan be used as an inline blower for ventilating a blowerless kitchen range hood? i.e. is it rated for exhausting steam and grease?**
A: I would have to say no for grease but yes it will work to vent steam even though it is not rated for this I have used them in my bathroom for over a year now and have not had any issue.

**Q: What happens if power goes out? Does it kick back on to same speed settings? How long would it hold thise settings with power out?**
A: If power is removed the fan will restart at same speed as operating before powered off. As far as how long will it retain speed setting, not sure but at least three weeks.

**Q: Would this be used in a cigar room in conjunction with a air purifier? Looking to build a cigar lounge in my house.**
A: i think so - i used it to improve air circulation in a 3 story house. i think it would work well for your purpose. it is quiet and has adjustable flow rate.
