eFlow-MAX Low Flow is a field adjustable High Capacity Constant Airflow Regulator. It is designed to automatically and precisely balance airflow into or out of a space without the need for electricity. Its design saves significant amount of energy, money and provides High Indoor Air Quality. This round damper is designed to provide pressure-independent maximum constant airflow in round duct systems without use of electricity, sensors or controls.
