G.A.S EC2 Thermo Fan Speed Controller — Dual-Fan Balance

G.A.S EC2 Thermo Fan Speed Controller — Dual-Fan Balance with Temperature Control

A compact but powerful EC controller with built-in fan balancer — thermostatically controls two EC fans simultaneously and lets you fine-tune intake and extract speeds for proper negative pressure. Powered directly by the fan via the included active cable, so there's no separate power pack needed.

Why growers choose the G.A.S EC2:

• Thermostatic control of two EC fans — temperature-responsive automation, not fixed speeds
• Built-in fan balancer — set intake and extract at different speeds for proper negative pressure management
• Compact form factor — small unit, big capability, doesn't dominate a control shelf
• Active cable included, plugs directly into fan — no extra power pack required, cleaner install
• Fine-tune your environment — precise speed targets, not fuzzy potentiometer dial
• Step up from single-fan AC1 — adds EC compatibility and dual-fan control

Who it's not for:

EC fans only — not compatible with AC fans. For single-fan setups, the G.A.S EC1 is cheaper. For HyperFan V2 specifically, the G.A.S HyperFan Controller V2 has matched compatibility. For full environmental integration (humidity, CO2, lighting), step up to the Enviro Controller V2.
