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.
