Featured eFlow USA Projects - Sven at
Queens Plaza Park, Long Island City, NY.
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,
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
eFlow-MAX constant airflow regulators as part of the building’s

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.

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 Classified 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.

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
It was designed by
Architects in charge of the project’s interior, lobby, and
amenities. The engineering firm Jaros, Baum & Bolles (JB&B)
Fulcrum Group provided mechanical engineering services.
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.
