Dampers

The Trans/Shield
Damper complete with 18 gauge stainless steel
Sliding Seal and Static Damper Plates with horizontal perforations which provide,
whilst the Seal Plate
is in the open position, a free area
of not less than that of the specially designed Grilles, for
the passage and transfer of ventilation air in either direction.
The Damper Sliding Plate is retained to the Damper Static Plate with
stainless steel shouldered rivets and fails-safe to the instant
closed
position, powered by two stainless steel tension springs,
with the melting and parting at a temperature of 72 °C
of an all brass Fusible Link attached to Sliding Seal
Plate, to form a fire resistant shield from either air flow direction.
The Fusible Link functions independently and regardless
of choice or status of Release and Reset Mechanism.
