The Aldes CEB3-CS Constant Exhaust Box is a ceiling register box which incorporates an automatic, pressure independent balancing damper that regulates exhaust airflow in duct systems to constant levels. The passive control element (CAR3) in the CEB3-CS requires no electric or pneumatic power, sensors, and works solely off system pressure. Each CEB3-CS includes mounting brackets, and all necessary hardware for installation.

The CEB3-CS 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, and provides significant savings on annual operating costs.

Other Information

N/A

    Construction
    • CAR3 constructed of amorphous thermoplastic resin enhanced with antimicrobial, anti-static, and flame retardant additives to improve material performance, reduce need for maintenance, and increase safety.
    • CAR3 is UL 2043 safety classified and labeled for flame and smoke generation (File No. R39897).
    • Galvanized steel register box with steel duct collar.

    Maintenance
    The CEB3-CS needs no maintenance when used in normal conditions. The addition of antimicrobial and anti-static additives in the material increases the longevity and reliability of the CAR3. There is no risk of dust deposit or obstruction because the CAR3 has no airways subject to clogging. If the intended application includes air heavily loaded with dust or grease, access to the CAR3 is possible by removing the grille.

    Warranty
    Guaranteed for 7 years, from date of shipment, against all defects in material or workmanship, provided that the material has been installed and used under normal conditions. This warranty is limited to the repair or replacement of the material.
