G.A.S AC1 Fan Controller — Entry-Level AC Speed Control

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

A straightforward plug-in AC fan controller from G.A.S — regulates your extraction fan speed in two modes: continuous at your minimum setting, or thermostatically (speeds up as room temperature rises). The entry-level controller for growers who want temperature-aware fan management without the complexity of multi-fan or EC-compatible units.

Why growers choose the G.A.S AC1:

• Two modes in one unit — continuous minimum speed, or temperature-responsive automation
• Plug-and-play installation — plug fan into controller, plug controller into wall, done
• Unplug sensor for continuous run — flexible operation depending on what you need
• Temperature sensor included — drop in the grow space for responsive fan control
• Entry-level pricing — proper AC speed control without paying for multi-fan or EC features
• Protects your fan motor — proper variable speed control extends fan lifespan vs on-off cycling

Who it's not for:

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