At eFlow USA, we never stop innovating. We are proud to announce that eFlow-Constant Airflow Regulator (CAR) design was updated to promote easy and efficient installation and identify CARs by static pressure. The CFM adjustment screw is now color coded to reflect each static pressure range.
At eFlow USA, we never stop innovating. We are proud to announce the launch of the new e2Flow® , the eFlow-CAR Dual Flow Damper. Available exclusively at eFlow USA! eFlow-CAR Dual Flow Dampers (e2Flow®) are self-regulating motorized dampers designed to introduce flexibility and dynamic control in central ventilation systems. The module opens and closes via a blade controlled by Belimo actuator, eliminating the need for expensive electronic control systems. e2Flow is available in 6”, 8”, 10”, 12” diamater. e2Flow features built...
A 2011 study, "Improving Central Exhaust Systems for Multifamily Buildings", concluded that sealing ventilation shafts and installing Constant Airflow Regulators at each exhaust vent can improve ventilation across the building. The study did not however, examine the impact on Indoor Air Quality. Now a new study, supported by a grant from the United States Department of Housing and Urban Development, investigated the impact of various ventilation upgrades such as the installation of Constant Airflow Regulators on indoor air quality (IAQ). Venting for...
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...
eFlow-Constant Airflow Regulators were installed in two buildings located at 265 and 275 Cherry Street , NYC . A Case study conducted by En-Power Group concluded that ventilation system upgrades, including the installation of 1,350 eFlow-Constant Airflow Regulators (CARs) in 490 units, not only improved Indoor Air Quality (IAQ) but also increased resident comfort and resulted in energy savings. Highlights and issues resolved with the installation of eFlow Constant Airflow Regulators included: *Overall improved Indoor Air quality in the building *Elimination of spreading...

What is Toilet Plume? Toilet plume occurs when the force of flushing the toilet sprays microscopic particles into the air. A study conducted by The CDC demonstrated that potentially infectious aerosols may be produced in substantial quantities during flushing. Aerosolization can continue through multiple flushes and may expose subsequent toilet users. Some of the aerosols desiccate to become droplet nuclei and remain adrift in the air currents. Research suggests that toilet plume could play a contributory role in the transmission of...
