Aoibox 120V 15A AC Motor Variable Speed Fan Speed Controller with Overload Protection and LED Display

Designed for AC motor applications up to 120V and 15A max, this fan speed controller works with hydroponics equipment, inline duct exhaust fans, and ceiling fans to help manage airflow for everyday ventilation and higher demand circulation

Variable speed control lets you fine tune fan output so airflow matches the ventilation needs of hydroponic grow rooms, duct exhaust systems, or ceiling fans, helping improve comfort and environmental control in multiple setups

Built in overload protection adds an extra layer of operational safety by helping protect connected AC motors and fan equipment in more demanding control setups, supporting dependable performance when adjusting speed under varying load conditions

An easy to read LED display shows key settings at a glance so you can quickly confirm speed levels, monitor operating status, and make adjustments as needed without interrupting fan operation in active ventilation environments

The controller unit measures 14 in x 6.1 in x 5.72 in, offering a space conscious footprint that fits into many indoor fan control installations while still providing accessible controls and clear visibility of the LED display during use

Use this AC motor variable speed controller when you need precise fan management for hydroponics systems, duct ventilation, or ceiling fan setups that benefit from adjustable airflow to support plant growth, air quality, or comfort
