G.A.S EC5 Fan Controller — Advanced Environmental Controller

G.A.S EC5 Fan Controller — Advanced Dual-Fan Environmental Control

G.A.S's advanced EC fan controller — full thermostatic control of intake and extract fans, plus the ability to balance fans precisely for optimum negative pressure management. The step up from the basic EC Speed Controller when you want temperature-responsive automation plus fan balancing rather than just fixed speeds.

Why growers choose the G.A.S EC5:

• Thermostatic control — fans speed up automatically as temperature rises, slow down when it drops
• Dual-fan balance control — intake and extract at different speeds for proper negative pressure
• Fine-tune setpoints — precise temperature targets, not just "warm" or "cool" presets
• Works with any G.A.S EC fan — plug-and-play compatibility
• Full environmental management in one unit — replaces multiple separate controllers
• Precise min/max speed limits — protect fans from running too slowly or at damaging max speed 24/7
• Supports temperature-sensor-driven automation — responds to actual grow-room conditions

Who it's not for:

Requires G.A.S EC fans — not compatible with AC fans or non-G.A.S EC fans. For single-fan setups, the AC1 Controller is cheaper. For full environmental automation including humidity and lighting, step up to the G.A.S Enviro Controller V2 which integrates more inputs.
