Questions about this item
When does the 165 °F fusible link need to be replaced?
The UL-listed fusible link rated at 165 °F is a single-use component; it must be replaced after it activates during a fire event.
What free-area limit restricts airflow in this 8 × 8 damper?
The damper provides 0.241 sq. ft. of free area, which is the primary airflow restriction under sustained operation.
How hot does the galvanized steel sleeve get during continuous low-pressure HVAC use?
The 22 ga. galvanized steel sleeve remains at normal duct temperature during continuous low-pressure HVAC operation; no additional heat is generated by the damper itself.
