eFlow-MAX Testing
Independent testing of eFlow-MAX High Capacity Constant Airflow Regulator was conducted by Weickert Industries, Inc at the request of Hunter Roberts Construction Group, for project : Sven at Queens Plaza Park.
Testing took place at the Queens Park Plaza Tower on September, 25, 2019. A system was built for testing purposes by Delta Sheet Metal Corp, an affiliate of PJ Mechanical Corp.
Four eFlow-MAX regulators set to specific CFM setting were put to the test over the entire pressure range from 0.2 to 4.0 w.g. (50-1000Pa)
A report issued by Weickert industries, Inc, dated September 27, 2019 illustrates findings of the tests as follows:
eFlow-MAX 4”, set to 45 CFM, over the entire pressure range of 0.25 to 4.0 in w.g. performed at an average of 46 CFM
eFlow-MAX 4”, set to 60 CFM, over the entire pressure range of 0.25 to 4.0 in w.g. performed at an average of 58.9 CFM
eFlow-MAX 4”, set to 50 CFM, over the entire pressure range of 0.25 to 4.0 in w.g. performed at an average of 54.6 CFM
eFlow-MAX 3”, set to 25 CFM, over the entire pressure range of 0.25 to 4.0 in w.g. performed at an average of 27.4 CFM
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 a significant amount of energy 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.
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 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. The Sven is situated adjacent to the historic Long Island City Clock Tower in Queens. The Sven will be the second-tallest skyscraper in the neighborhood . Completion of the project is expected in 2021.
eFlow-MAX is equal to Aldes MR MAX
