CER3-S-F

The Aldes CER3-S-F Constant Exhaust Register with integral fire damper incorporates an automatic, pressure independent balancing damper that regulates airflow in duct systems to constant levels. The passive control element in the CER3-S-F requires no electric or pneumatic power or sensors and works solely off system pressure.

The CER3-S-F compensates for changes in duct pressure caused by stack effect, operable windows and doors, wind, loading filters, etc. CER3-S-F 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.

CER3-S-F shall be provided as an assembly consisting of a CAR3*, painted aluminum grille fire damper and galvanized steel sleeve assembly to install in square or rectangular duct. Fire damper must be classified per UL 555 and carry the UL mark indicating compliance. Fire damper shall be dynamic type and have a minimum rating of 1.5 hours.
