eFlow-Constant Airflow Regulators Low Pressure were installed at 1133 Broadway, NYC.

eFlow-Constant Airflow Regulators (CAR) Low Pressure (LP) are designed for systems with in (0.08” wc -0.4” wc) pressure range. eFlow-CARs LP are devices that automatically regulate airflow in ventilation systems to constant levels without the use of electricity, sensors or controls. The eFlow-CAR LP is a low-cost solution to balancing forced-air systems for heating, air conditioning and ventilation, eliminating the need for on-site balancing while promoting energy savings and high indoor air quality.
