eFlow-CAR Dual Flow Classified UL 2043 (R38307) self-regulating motorized dampers are designed to introduce flexibility and dynamic control to central ventilation systems. Used in both large and small systems, the eFlow-CAR Dual Flow, regulates ventilation without the need for individual fans. The module opens and closes via a blade controlled by an electric motor, eliminating the need for expensive pneumatic electronic control systems. eFlow-CAR Dual Flow is available in 5”, 6” and 8” diameter.
eFlow-CAR Dual Flow features two built in eFlow-CARs to allow for minimum and maximum flow. It combines low-flow indoor air quality ventilation and on-demand high-flow ventilation while using the same central fan system. In the “off cycle” position, the factory-calibrated eFlow-CAR allows for steady, low-flow ventilation. In the “on cycle”, the maximum flow rate is ensured.
eFlow-CARs are factory set Constant Airflow Regulators that are designed to save significant amount of energy by precisely controlling airflow into or out of a space. This is done regardless of static pressure. The use of eFlow CARs helps ensure High Indoor Air Quality (IAQ). eFlow-CARs are composed of UL94V-0 ABS plastic and are UL 2043 safety classified (labeled for flame and smoke generation). They feature a self-regulating aero-wing and spring piston design to maintain factory preset air flows.
