Launching e2Flow®, the eFlow-CAR Dual Flow Damper

At eFlow USA, we never stop innovating. We are proud to announce the launch of the new e2Flow® , the eFlow-CAR Dual Flow Damper. Available exclusively at eFlow USA! 

eFlow-CAR Dual Flow Dampers (e2Flow®) are self-regulating motorized dampers designed to introduce flexibility and dynamic control in central ventilation systems. The module opens and closes via a blade controlled by Belimo actuator, eliminating the need for expensive electronic control systems. e2Flow is available in 6”, 8”, 10”, 12” diamater. e2Flow features built in eFlow-CAR to allow for minimum controlled airflow. It combines low-flow 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 (min setting). In the “on cycle”, the maximum flow rate is allowed. eFlow-CARs are factory set Constant Airflow Regulators that are designed to save a 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.
