Aldes MR Modulo Series Adjustable Constant Airflow Regulators

American Aldes MR Modulo Adjustable Constant Airflow Regulators are modulating orifices that automatically regulate airflows in duct systems to constant levels. The passive control element responds to duct pressure and requires no electric or pneumatic sensors or controls. The MR Modulo compensates for changes in duct pressure caused by thermal stack effect, building pressure, dust-clogged filters, etc. The MR Modulo also provides a low-cost solution to balancing forced-air systems for heating, air conditioning and ventilation, eliminating the need for on-site balancing.

Pressure Range: 0.2 to 1.0 in. w.g. (50-250 Pa)
Available Diameters:  4", 5", 6", 8", 10"
Airflow Range: 10-380 CFM
Use: Exhaust or Supply Air

#1 Q:   So what happens if the pressure drop becomes much greater? Such as 1 PSI. Can this product still limit the flow?
A:   No. Its only designed to work in the 0.2 to 1.0 in. w.g. range. 1 PSI is well outside the acceptable range.
