8 Court Square, Long Island City, NY

8 Court Square building is nearly complete and features variety of eFlow-products for automatically balanced and controlled ventilation.

8 Court Square is a 20-story residential tower located at 27-10 44th Drive in Long Island City, NY. This 224-foot-tall structure will yield 107,377 square feet of residential space spread across 157 units, as well as 10,170 square feet for commercial space.

eFlow-CARs 4″ at 25 CFM were installed in every apartment exhaust. eFlow-CAR 6″ high pressure (0.6″w.c.-2.4″w.c.) at  125 CFM in wall mount fire damper assemblies were utilized for supply application. e2Flow PLUS system was installed to control on demand high airflow. e2Flow PLUS is exclusive to eFlow and it’s used as ZRT alternative solution.

8 Court Square was developed by 25-34 Jackson Avenue Property Owner LLC, designed by Hill West Architects and Cauldwell Wingate Company is the general contractor on record. Installation of eFlow-Products was undertaken by PI mechanical.

The manufacturers representative, SRS Enterprises, Inc,  facilitated the sale of eFlow products for this project.

8 Court Square is expected to be completed  in 2023.



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.

Flow-CAR Fire Damper Assembly FACTS 

eFlow-CAR is inserted in a heavy-gauge galvanized steel enclosure that is designed to accommodate installation of fire damper and standard aluminum grille. eFlow-CAR is removable from the assembly to allow for easy CFM adjustment. Each enclosure is designed to specifically accommodate eFlow-CAR and expertly welded to prevent unwanted air leakage. The assembly is custom sized for each project.

Available Options:

● Supply Application
● Exhaust Application
● Back inlet
● Side inlet
● Top inlet
● UL rated 555, 1 ½ hours, thin line Fire damper
● Aluminum grille
● Retrofit Gasket


e2Flow® PLUS FACTS (ZRT Alternative Solution)

e2Flow® PLUS system is designed to introduce flexibility and demand control to central ventilation systems. It is used to achieve a combination of low-flow continuous indoor air quality ventilation and on-demand high-flow spot ventilation using the same central fan system. This high efficiency ventilation system promotes high indoor air quality, energy savings and reduces operating costs. This system is used in both large and small systems. Unlike any other product on the market, e2Flow® PLUS offers flexibility in engineering design where system’s components are tailored to the project’s requirements. Combination of two eFlow devices are used to achieve controlled minimum and maximum airflow. e2Flow® PLUS offers simple in-line installation where no mounting hardware or additional support is required. 

e2Flow® PLUS is ideal for bathroom, kitchen exhaust, makeup air, new constructions, retrofits and so much more. 

  • Achieve a combination of low-flow continues ventilation and on-demand high-flow spot ventilation
  • Mix & Match eFlow products for optimal solution
  • Easy in-line installation
  • No mounting hardware or additional support required
  • Low installation cost 
  • Refer to schematic for installation illustration
