The GAF series contains a cutting-edge Electronically Commutated (EC) motor, controlled using precise electronic pulses and smart programming. This enables the GAF fan to increase its speed to boost airflow at a lower noise level. The EC motor is more energy efficient then AC-motors and can save up to 30-80% in energy costs, paying for itself in the long run. Simply put, the GAF is designed to cool and ventilate greenhouses by constantly moving air when needed. Innovative EC-motor with PWM customizable fan speed control, maximizes airflow while reducing energy consumption and noise levels.
