eFlow USA delivered Constant Airflow Regulator solution for Clarkson Estates located at 329 Clarkson Avenue, Brooklyn, NY. This 9-story, 328-unit new construction development is targeting Passive House certification.
To meet Passive House ventilation standards, MB Mechanical installed a combination of 4” eFlow-Constant Airflow Regulators (CARs) for kitchen and bathroom exhausts, and 6” and 8” eFlow-CARs for supply air applications—ensuring precise, automatically balanced ventilation throughout the building.

eFlow-CAR FACTS
eFlow-CAR is a simple solution to balancing ventilation systems. Constant Airflow Regulator is a device that automatically regulates airflows in ventilation systems to constant levels. The passive control element responds to duct pressure, and requires no electric sensors, pneumatic sensors or controls. eFlow-CARs promote high indoor air quality and energy savings.
