The renovation of 753 Classon Avenue, a 13-story affordable housing building in Brooklyn, featured the installation of eFlow-CAR Ceiling Mount Fire Damper Assemblies and Wall Mount Fire Damper Assemblies. These advanced airflow solutions were engineered to enhance ventilation safety, fire protection, and long-term energy efficiency. Originally constructed in 1967, the 137-unit building is undergoing full rehabilitation supported by $51 million in funding from New York State. Ventilation installation was led by G & G Mechanical Corp., Inc, with design oversight from Newman Design Architects and Architectural Preservation Studio, DPC. The general contractor on the project is MDG Design & Construction.
Built to Last. Rebuilt for the Future.
With a focus on preserving legacy housing stock while upgrading to modern performance standards, 753 Classon Ave is a prime example of retrofit-driven sustainability. The project leverages eFlow Constant Airflow Regulators (CARs) to improve exhaust ventilation consistency, reduce HVAC strain, and enhance resident comfort.

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.
