ZRT Alternative Strategy by eFlow USA: A Dual Flow Breakthrough for High-Rise Ventilation
eFlow USA delivered a customized ZRT alternative ventilation system for 410 West 126th Street, New York, NY, a 20-story, 92-unit new construction project. Developed by Columbia International and designed by Peter Poon Architects, this building demanded a high-performance airflow solution that could meet strict air quality, balance, and energy targets.
Working closely with Global Contractor Supply and product representative Mechanical Technologies, eFlow supplied its advanced e2Flow PLUS system, the ZRT Alternative Solution.

Project Challenge
This project required a dual-setpoint system capable of handling both minimum and maximum CFM targets across exhaust and supply ducts.
eFlow Solution: e2Flow PLUS System
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, 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 system’s components are tailored to the project’s requirements. Combination of two eFlow devices are used to achieve controlled minimum and maximum airflow. e2Flow® PLUS offers simple in-line installation where no mounting hardware or additional support is required.
Exhaust Ventilation:
- e2Flow 8” at 50 CFM (Min Flow Control)
- Combined with eFlow-MAX 8” at 250 CFM (Max Flow Control)
Supply Ventilation:
- e2Flow 8” at 50 CFM (Min Flow Control)
- Paired with Ceiling Mount Assemblies at 250 CFM (Max Flow Control)
This dual-control system maintains precision at both low and high flow set-points. The result is a high-performance ZRT alternative that offers simpler installation, flexibility in design, silent operation, reduced maintenance

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.
