GAS EC1 CONTROLLER

Description

GAS EC1 Controller is a compact, single-fan EC speed controller for electronically commutated (EC) inline fans, providing precise manual speed adjustment and the correct EC control signal format that EC motors require for stable, efficient operation across the full speed range. We have been recommending GAS EC fan control products to UK growers since 2017 as the professional solution for managing EC fan-based ventilation systems with the accuracy and simplicity that indoor growing requires.

Why the GAS EC1 Is the Right Controller for Single EC Fan Installations

EC fans are significantly more efficient and controllable than AC motor fans, but they require a specific 0–10V or compatible control signal to operate at variable speeds — standard AC triac dimmers will not work correctly with EC motors and can damage the motor electronics if connected. The GAS EC1 generates the correct control signal for compatible EC fans, allowing stepless speed adjustment from minimum to maximum with genuine precision that standard triac dimmers cannot achieve. At any speed setting in the range, the EC motor maintains that speed stably without hunting or oscillation — delivering the precise airflow management that determines how well your grow room climate can be controlled. The EC1 single-output format is matched to installations with one EC fan, keeping the control setup simple and cost-effective. For multi-fan installations, the GAS EC Active Splitter Cable or the higher-output GAS EC controller models allow multiple fans to be controlled from a single unit.

How to Set Up the GAS EC1 Controller

Connect the EC1 to your EC fan using the appropriate control cable — refer to your fan’s documentation for the correct connector specification. Power the controller and use the adjustment dial to set your desired fan speed. Set minimum speed to maintain adequate baseline air exchange even at the lowest required ventilation level, and maximum speed to the rate that maintains your target environment under peak demand conditions. Monitor temperature and humidity in the grow space and adjust fan speed as seasonal conditions change. The EC1 is compatible with GAS EC fans and a range of other EC inline fans — confirm compatibility with your specific fan model before purchase.

Pair the GAS EC1 Controller with a GAS EC inline fan, Can-Lite or Carbo Air carbon filter, and Phonic Trap acoustic ducting for a complete, energy-efficient EC ventilation system. Browse our full GAS fan and controller range.
