Static Systems
Static applications are where the HVAC systems fans are automatically shut down in the event of a fire and for use in air transfer openings in walls or partitions. The static-rated fire damper is only tested for use when there is no airflow present in the system.
All Duro Dyne static damper frames and blades are constructed with 22 gauge roll-formed galvanized steel and have replaceable 165°F or 212°F fusible links.
