FIRESHIELD

** Cassette Mechanism**

• Patented design.
• Made of Polyphenylene sulphide (PPS) resin reinforced with 40%glass (GF-PPS).
• Technically advanced engineering polymer.
• PPS is stable at temperatures up to 200 °C.
• Cassette construction is of very high strength and has excellent creep and fatigue resistance.
• Low smoke and toxic emissions in fire conditions.
• Halogen free.
• PPS has a very low moisture absorption.
• PPS is corrosion resistant.
• The Cassette construction is environmentally friendly (recyclable material).
• The new Cassette is retrofittable to existing FireShield Dampers (by use of a simple optional adaption bracket. Part Number: CNNN01981).
• One Cassette to suit all damper material options.

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.
