eFlow USA supplied hundreds of 5″ Constant Airflow Regulators (CARs), calibrated at 30 CFM, for The Brook — a 601-foot, 51-story residential skyscraper at 589 Fulton Street, Downtown Brooklyn, NY. The project team includes Beyer Blinder Belle (Project Architect), Cosentini Associates (Engineer), Suffolk Construction (General Contractor), Witkoff Group and Apollo Global Management (Developers), Centrifugal Associates Group (Installer of eFlow products), with eFlow products sold through SRS Enterprises Inc..
Redefining Ventilation in Brooklyn’s Tallest Tower
As one of New York’s tallest construction projects in 2024, The Brook delivers 591 modern rental apartments across 51 stories. With eFlow-CARs installed throughout, the tower benefits from consistent, balanced exhaust ventilation that reduces HVAC inefficiency while supporting resident comfort in a dense, high-rise setting.

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.
