eFlow is proud to announce that Sven at Queens Plaza Park, Long Island City, NY will feature over 3,000 of eFlow-MAX High Capacity Constant Airflow Regulators and eFlow-Constant Airflow Regulators (CARs). Residents of this building will enjoy an automatically balanced, high-efficiency ventilation system that will provide high indoor air quality and energy savings. The manufacturer’s representative, Mechanical Technologies, facilitated the sale of eFlow products for the Queens Park Plaza project. This is the first project of this magnitude in the USA to utilize eFlow-MAX constant airflow regulators as part of the building’s ventilation system.
About Sven
Sven is a new 755-foot tall residential tower located at 27-29 Queens Plaza North and 29-37 41st Avenue in Long Island City. This 67-story tower is owned and has been developed by the Durst Organization. It was designed by Handel Architects, with Selldorf Architects in charge of the project’s interior, lobby, and amenities. The engineering firm Jaros, Baum & Bolles (JB&B) and The Fulcrum Group provided mechanical engineering services. HRCG-Hunter Roberts construction group carried out the construction of the project and Delta sheet metal and PJ mechanical were the mechanical contractors for the project.
Sven will feature 958 residential units, 287 of which will be dedicated to affordable housing. The tower will include an outdoor pool, fitness center, resident’s library, co-working space, children’s playroom, and a demonstration kitchen. Sven is situated adjacent to the historic Long Island City Clock Tower in Queens. Sven will be the second-tallest skyscraper in the neighborhood . Completion of the project is expected in 2021.
About eFlow-MAX
eFlow-MAX is a field adjustable High Capacity Constant Airflow Regulator. It is designed to operate within Pressure Range: 0.2 to 4.0 in w.g. (50-1000Pa), automatically and precisely balance airflow into or out of a space without the need for electricity. Its design saves significant amount of energy, money and provides High Indoor Air Quality. This round damper provides pressure-independent maximum constant airflow in round duct systems without the use of electricity, sensors or controls. As pressure increases, the blade moves to keep airflow stable over a wide pressure range. eFlow-MAX has an external mechanism that can be used to adjust airflow manually, and with ease, using an allen wrench (2mm). eFlow-MAX can be easily installed inside standard ductwork. Mounting may be horizontal or vertical. eFlow-MAX features laser-welded, heavy galvanized steel body, plastic airflow control and an airtight seal to ensure no-leak fit. eFlow-MAX is maintenance free and corrosion-proof under normal conditions.

About eFlow-CAR
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 for commercial and residential buildings. The requested 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.
