Launching eFlow-MAX +, the next-generation of the eFlow-MAX High Capacity Constant Airflow Regulator

At eFlow USA, we never stop innovating. We are proud to announce the launch of the new eFlow-MAX +.

Available now at eFlow USA!

eFlow-MAX+ is the next-generation of the eFlow-MAX Constant Airflow Regulator. This enhanced version showcases an advanced, durable, easy to adjust lock-in nub for CFM control, meticulously designed for optimal performance and efficiency.

eFlow-MAX + is a field adjustable High-Capacity Constant Airflow Regulator. It is designed to automatically and precisely balance airflow into or out of a space without the need for electricity. Its design saves significant amounts of energy, money and provides High Indoor Air Quality. This round damper is designed to provide pressure-independent maximum constant airflow in round duct systems without use of electricity, sensors or controls. As pressure increases, the blade moves to keep airflow stable over a wide pressure range. This new eFlow-MAX + features an updated external mechanism that can be used to adjust airflow manually, and with ease, without any tools. eFlow-MAX + can be easily installed inside standard ductwork. Mounting may be horizontal or vertical.

eFlow-MAX + features laser-welded, heavy galvanized steel body, aluminum control plate, solid plastic airflow control and airtight seal to ensure no-leak fit. It is also available in stainless steel.

eFlow-MAX + is maintenance free and corrosion-proof under normal constitutions.

Warranty is guaranteed for Five (5) years, from date of shipment, against all defects in material, given that the material has been installed and used under normal conditions. This warranty is limited to the repair and replacement of material.
