e2Flow Revolutionizing Central Ventilation Systems

Ventilation systems form the backbone of comfortable and healthy indoor environments. As industries evolve and needs shift, central ventilation systems must adapt and innovate. eFlow’s e2Flow® stands as a testament to such innovation, introducing flexibility and dynamic control that’s unparalleled in the market.

e2Flow® PLUS system is designed to introduce flexibility and demand control to central ventilation systems. It is used to achieve a combination of low-flow continuous indoor air quality ventilation and on-demand high-flow spot ventilation using the same central fan system. 

This high-efficiency ventilation system promotes high indoor air quality, and energy savings and reduces operating costs. This system is used in both large and small systems. Unlike any other product on the market, e2Flow® PLUS offers flexibility in engineering design where the system’s components are tailored to the project’s requirements. A combination of two eFlow devices is used to achieve controlled minimum and maximum airflow. e2Flow® PLUS offers simple in-line installation where no mounting hardware or additional support is required.

e2Flow® PLUS is ideal for bathroom exhaust, makeup air, new constructions, retrofits and so much more.

 eFlow-CAR Dual Flow Dampers (e2Flow®) are self-regulating motorized dampers controlled by Belimo actuators. e2Flow features built-in eFlow-CAR to allow for minimum controlled airflow. 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. 

e2Flow® will regulate airflow in supply or exhaust applications. For complete product information, please visit eflowusa.net and refer to the e2Flow® submittal data sheet. 

e2Flow® stands out for its innovative features and its role in the e2Flow PLUS system (ZRT alternative solution) for controlling minimum airflow. Here’s what sets it apart:

  • Self-Regulating Motorized Dampers:  e2Flow® features a self-regulating mechanism, eliminating the need for manual adjustments. It responds in real-time to the demands of the ventilation system, ensuring efficient airflow control.
  • Flexibility in Application: Designed to adapt,  e2Flow® fits seamlessly into various settings, from residential buildings to commercial complexes. It provides tailored solutions for diverse requirements.
  • Dynamic Control: Beyond just regulating airflow,  e2Flow® optimizes it. Its dynamic control system ensures even and efficient air distribution, maintaining a consistent indoor environment.

Control Minimum Flow:  e2Flow® offers the capability to control minimum airflow, making it a versatile and efficient choice for maintaining indoor air quality.

Benefits of e2Flow® in Central Ventilation

  • Energy Efficiency: By ensuring optimal airflow, e2Flow® significantly reduces energy consumption, leading to decreased utility bills and a reduced carbon footprint.
  • Reduced Maintenance: With its self-regulating feature, e2Flow® minimizes wear and tear, effectively reducing the frequency and costs of maintenance.
  • Enhanced Indoor Air Quality (IAQ): By maintaining consistent airflow, e2Flow® ensures that indoor pollutants are effectively filtered out, leading to improved IAQ, which is essential for health and well-being.


The e2Flow® from eFlow is not just a product; it’s a vision for the future of central ventilation systems. As industries move towards smarter and more efficient solutions, e2Flow® sets the benchmark, promising a blend of innovation, efficiency, and reliability.Upgrade to a smarter ventilation solution with e2Flow®. Contact us at 1-833-356-9872 to know more about how it can revolutionize your building’s ventilation.
