AHRI 1290 (I-P/2017): Performance Rating of Zone Dampers
This standard applies to zone dampers, as defined in Section 3 of this standard. It defines the performance of zone dampers with respect to pressure drop, airflow leakage, airflow rate, and operational torque. This will provide specifiers and users with the data required to evaluate and compare zone dampers.
