Material and surface treatment

Casing Features The spigotted casing with continuously welded corners and spigot connections, makes these dampers suitable for inclusion into air distribution systems to the test methods of Eurovent Class A, B & C and HVCA Ductwork specification DW144. These galvanised casings are manufactured with either all square, rectangular and circular ductwork

Blade Features The Type 1.4016 (430) Ferritic Stainless Steel folding blade curtain, providing maximum strength, forms a fire shield. The wide profile blades maximise the damper free area and ensure compact grouping to minimise blade stacking height.

Stainless Steel Closure Springs Stainless Steel constant tension springs are fitted and positioned out of the airstream to close and latch the damper, regardless of vertical or horizontal operation.
