Better Efficiency All Year Long
PROMOTION — Lennox’ patent-pending MSAV® supply fan technology helps reduce energy use while still meeting comfort requirements. Factory-installed on Lennox’ 7.5- to 25-ton Energence® rooftop unit models, the MSAV supply fan uses a variable frequency drive to lower airflow during part-load cooling, heating, ventilation and free cooling operation modes to dramatically reduce energy costs all year long.
