Lennox SmartAirflow System


The Lennox SmartAirflow system is 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 on  annual ventilation energy consumption.

SmartAirflow works with an economizer and the Prodigy Control System on the Energence rooftop unit to accurately manage fresh air ventilation throughout the day. This precise and continuous control of airflow helps prevent over- and under-ventilation resulting in significant cost savings each month, as well as optimal indoor air quality.

In addition, SmartAirflow provides five independent adjustable supply airflow settings.  This allows for lowering of airflow for modes where higher speeds are not needed resulting in further supply fan power savings.

SmartAirflow is easy to install and setup reducing time spent on the job. This significantly cuts down on commissioning time while ensuring the system is setup correctly. Additionally, to facilitate greater building automation and monitoring, the SmartAirflow System is compatible with optional BACnet and LonTalk modules which provide enhanced operational data with customizable diagnostics.
