Whitehall Building, 17 Battery Place, NYC, a landmark overlooking Battery Park in Lower Manhattan, now has 4” eFlow-Constant Airflow Regulators (CARs) set at 20 and 25 CFM, supplied by eFlow USA and installed by BAM Mechanical Group as part of a retrofit. The 31-story Financial District building, a New York City landmark since 2000, includes 492 rental apartments and affordable housing.
Retrofit Ventilation for a Lower Manhattan Landmark
The Whitehall Building was completed in 1904 and expanded with a larger annex in 1910, and its upper floors have since been converted to rental apartments. The retrofit uses 4” eFlow-CARs, which hold a set airflow automatically as duct pressures change, with no electricity and no sensors.

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.
