eFlow USA is proud to support one of the most significant residential redevelopment projects in the country. For SoMA at 25 Water Street, we supplied thousands of eFlow-CAR Constant Airflow Regulators and Custom Mounting Plate Assemblies., contributing to the largest office-to-residential conversion in the United States.This massive undertaking has transformed a 1960s Brutalist office tower in the Financial District into a vibrant luxury complex with 1,320 apartments. All-City Metal Inc handled the massive eFlow-CAR installation scope.
Breathing New Life into a Concrete Giant
Converting a massive office floorplate into 1,320 residential units requires a ventilation strategy of unprecedented scale and precision. The “deep floor plates” typical of office towers create complex airflow challenges for residential retrofit. eFlow USA stepped up with a massive supply of thousands of 5″ Constant Airflow Regulators (CARs) and Custom Mounting Plate Assemblies (3″ and 4″ regulators in 5″x4″ plates). This bespoke solution ensures that every unit—from the studio apartments to the sprawling 3-bedrooms—receives precise, code-compliant ventilation (20-45 CFM) despite the building’s immense size and unique retrofit constraints.

Why eFlow-CARs Matter for Office-to-Residential Conversions
- The “Conversion” Solution – Our custom mounting plates (e.g., 5″x4″) allow seamless integration into existing commercial ductwork, solving the biggest headache of adaptive reuse.
- Scaleable Performance – Whether it’s 50 units or 1,320, our passive regulators deliver consistent airflow without complex electronic control systems.
- Energy Efficiency – Critical for bringing older 1960s structures up to modern energy codes (Local Law 97 ready).
- Mixed-Unit Flexibility – Multiple CFM settings (20-45) handle the varied needs of studios, 1-beds, and 2-beds within the same stack.

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.
