Key Features

Smoke damper frame is of 180GSM galvanized steel of 16Ga thickness formed into a structural hat channel in 4-piece construction with integral overlapping gusset reinforcements (screws are not acceptable) in each corner to ensure perfect square shape. Top and Bottom frame members will be of low profile design to maximize the free area on small dampers less then 425mm height and hence minimize pressure drop.
