eFlow USA supplied a large quantity of 6″ Constant Airflow Regulators (CARS) for the new-construction Reston Row District in Reston, Virginia. eFlow worked directly with Vertical Mechanical Group as the installer of eFlow products to deliver precise exhaust balancing across the buildings.
Optimizing Airflow in a Modern Mixed-Use District
Reston Row District introduces a new urban community with apartments, condos, hotels, and retail. By integrating eFlow-CARs into its ventilation systems, the project ensures passive, reliable airflow balancing at the source—supporting comfort, energy efficiency, and long-term system performance in a large-scale development.

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.
