Overview

American Aldes CER-FEA-II Constant Exhaust Registers incorporate a modulating orifice that automatically regulates 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 CER-FEA-II compensates for changes in duct pressure caused by thermal stack effect, building pressure, dust-clogged filters, etc. The CER-FEA-II also eliminates the need for on-site balancing.

Aldes CAR’s, CER’s & CSR’s with fire dampers are the only ETL Safety Certified assembled units on the market today!

The active control element is a unique aerofoil. The aero-wing damper lifts in response to increasing static pressure. This operation regulates the free-area opening through the control, resulting in maintenance of velocity and specific airflow set points.
