The Aldes CEB3-CS-F Constant Exhaust Box is a ceiling register box with integral ceiling radiation damper which incorporates an automatic, pressure independent balancing damper that regulates exhaust airflow in duct systems to constant levels. The passive control element, or CAR3, in the CEB3-CS requires no electric or pneumatic power or sensors, and works solely off system pressure. Each CEB3-CS-F includes mounting brackets and necessary hardware for installation.
The CEB3-CS-F compensates for changes in duct pressure caused by stack effect, operable windows and doors, wind, loading filters, etc. The CEB3-CS provides a low-cost solution to maintaining the correct airflow balance of ventilation systems, improving system performance and indoor air quality, which can provide significant savings on annual operating costs.
The plenum box casing shall be minimum 24-gauge G90 galvanized steel with an integral steel duct collar that allows attachment of both rigid and flexible ducting. The collar shall be sized to allow full insertion of a model CAR3 Constant Airfow Regulator for airflow control, but without the regulator extending into attaching duct. Each CEB3-CS-F shall include all necessary mounting brackets and hardware.
