AC Infinity - CLOUDLINE S8 - Quiet 8” Inline Duct Fan with Speed Controller - Ventilation Exhaust Fan

[shortdesc]  Duct Size 8 in. Total Airflow 807 CFM  Total Noise 39 dBA [/shortdesc] A 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. Features an inline speed controller utilizing PWM-technology. Contains a mixed-flow design and EC-motor for a quiet and high static-pressure performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one duct fan unit, one corded speed controller, installation manual, and all necessary mounting hardware. The inline speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. Unlike common AC-powered duct fans that suppresses voltage to control fan speeds, this duct fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation). This techn
