eFlow supplied 3” CARs mounted in custom 6” x 4” plates to support the energy-efficiency upgrades at 22 Bowers Street, a seven-story affordable housing complex in Lowell, Massachusetts. The 138-unit building, originally built in 1976, recently underwent a major retrofit to modernize ventilation and improve indoor air quality. eFlow product integration were coordinated in collaboration with Aeroseal, ensuring precise airflow balance across all units.
Affordable Housing with Modern Performance
The transformation of 22 Bowers Street focused on preserving affordable housing stock while improving ventilation, insulation, and mechanical systems. The building now benefits from precise, power-free airflow regulation at the unit level—supporting lower energy bills and better indoor air quality for residents.

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.
