Lennox has introduced the SmartAirflow™ system, available on 3- to 5-ton high-efficiency Energence® rooftop units. This new sensor-based system is a factory installed option that measures, controls, and verifies supply and ventilation airflow. The SmartAirflow system increases supply fan power savings and can save an average of 35% of annual ventilation energy consumption, according to the company.
