e2Flow®: Advanced Dual Flow Dampers : Revolutionizing Dynamic Ventilation Control
e2Flow® are self-regulating motorized dampers designed to provide flexible, dynamic control in central ventilation systems. Available in 6”, 8”, 10”, and 12” diameters, e2Flow® operates via a Belimo actuator, eliminating the need for complex electronic controls. With an integrated eFlow-CAR Constant Airflow Regulator, e2Flow® maintains steady low-flow ventilation during the “off” cycle and allows high-flow ventilation on demand in the “on” cycle.
For enhanced airflow management, e2Flow® can also be installed in-line with another constant airflow regulator, such as eFlow-CAR or eFlow-MAX, to independently control both minimum and maximum airflow levels.
Why Choose e2Flow®?
- Seamless Dual Flow Functionality: Transition effortlessly between steady low-flow ventilation during “off cycles” and full-flow during “on cycles,” all while using the same central fan system.
- Integrated eFlow-CAR Technology: Factory-calibrated Constant Airflow Regulators maintain consistent airflow, irrespective of static pressure, for efficient ventilation and energy conservation.
- Robust Design: Constructed with galvanized steel and incorporates eFlow-CAR (UL94V-0 ABS plastic), ensuring durability, minimal maintenance, and flame safety certification (UL 2043).
- Simplified Installation: Inline design requires no additional mounting hardware, making it suitable for new installations and retrofits.
- Energy Efficiency and Cost Savings: Reduces HVAC strain by optimizing airflow distribution, resulting in lower energy costs and operational efficiency.
