G.A.S AC1 Fan Controller — AC Fan Plug-In

G.A.S AC1 Fan Controller — Plug-In AC Speed Controller

The easy, effective way to control AC fans — plug the fan into the AC1, plug the AC1 into the wall, dial in your setting, done. Two modes: continuous minimum speed (unplug the sensor) or thermostatic operation (plug the sensor into the grow space for temperature-responsive control). The entry-level controller for AC fan setups.

Why growers choose the G.A.S AC1:

• Two operating modes — continuous minimum speed, or thermostatic with the temperature sensor
• Plug-and-play installation — plug fan into controller, controller into wall, job done
• Sensor plugged in = temperature-responsive — fan speeds up as room heats
• Sensor unplugged = continuous low speed — flexible operation without mode switches
• Temperature sensor included — everything you need in the box
• Entry-level pricing — proper variable-speed AC control at an accessible price
• Protects fan motor — proper variable speed vs cheap on-off cycling extends fan lifespan

Who it's not for:

Single-fan AC only — for EC fans (HyperFan V2, Revolution Vector), use an EC-compatible controller (G.A.S EC1/EC2/EC5). For twin-fan AC setups, step up to an SMS Twin Controller. Not compatible with LED driver dimming control.
