Another NYCHA building to install eFlow-Constant Airflow Regulators!
344 East 28th Street is a towering residential complex located in New York City, comprising 26 floors and 225 units ranging from 1 to 4 bedrooms. Built in 1971, it is home to around 450 residents who primarily fall under the low- and extremely-low-income bracket.
This building is part of The New York City Housing Authority (NYCHA) which is a government agency that provides affordable housing to low- and moderate-income New Yorkers. It is the largest public housing authority in North America, serving over 400,000 residents in over 300 developments across the five boroughs of New York City.
As with most multi-unit buildings, energy conservation is a primary concern for 344 East 28th Street. To address this issue, eFlow Constant Airflow Regulators were installed to ensure the proper balance of ventilation and reduce energy usage. To facilitate this installation, eFlow provided custom 6”x4” mounting plates to accommodate 3” CAR at 25 CFM as well as 6″x4″ fire dampers in every apartment exhaust.
The project’s architectural design was led by SLM Architecture, while Monadnock Construction assumed the role of general contractor. The MEP engineering work was handled by Dagher Engineering, while eFlow collaborates with Rehab and Design Construction Corp. to provide eFlow products for the project.

eFlow-Constant Airflow Regulator (CAR) is a low-cost solution for balancing ventilation systems, eliminating the need for on-site balancing and ongoing maintenance. The Constant Airflow Regulator’s control of airflow is essential to optimize energy consumption while providing good air quality. eFlow-CARs are UL 2043 Classified (R38307) devices that automatically adjust to environmental changes in stack pressure and accurately regulate airflow. Constant Airflow Regulators are self-regulating and adjustable flow-regulators used in commercial and residential buildings. The desired airflow is fixed by a screwdriver. It is automatically calibrated to varying pressures without the need for electricity. Constant Airflow Regulators save energy by precisely controlling airflow into or out of a space. This is accomplished regardless of static pressure while providing good air quality.
