eFlow USA is proud to have contributed to North Cove at 375 West 207th Street, a major 100% affordable housing development in Upper Manhattan. The project included the supply of hundreds of 4″ eFlow-CAR Constant Airflow Regulators, calibrated for 10–30 CFM, supporting consistent ventilation performance across 611 residential units.
The project team includes Aufgang Architects (Project Architect), Joy Construction Corporation and Maddd Equities (Developers), with installation by ALL ABOUT AC. eFlow products were sold through our representative, Mechanical Technologies.
Equity in Air Quality for 30 Stories
Designing a 30-story affordable housing tower presents a distinct challenge: the “stack effect.” Without proper regulation, upper floors suffer from over-ventilation while lower floors stagnate. For North Cove, eFlow-CARs provide the solution, ensuring that every family—from the 1st floor to the 30th—receives the exact same airflow. This passive balancing prevents energy waste, lowering utility costs for the building while guaranteeing healthy indoor air quality for all 611 households.
eFlow-CAR at a Glance

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.
