Aldes CEG-II Constant Exhaust Grilles are the latest generation of exhaust grilles for round ducts. The CEG-II automatically regulates airflows in exhaust duct systems to constant levels. The passive control element responds to duct pressure and requires no additional sensors or controls. Each CEG-II can be field adjusted to multiple setpoints. The CEG-II is a low-cost solution to balancing airflow in multi-point exhaust systems because it eliminates the need for on-site damper adjustment. Models CEG-II and CEG-II Twin are available. CEG-II’s fit 5″ round ducting or mount directly over duct openings (depending on model). A Wall-Adapter Plate is available.
