Transfer Stainless Steel Sliding Plate Fire and Smoke 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.
