Features

• Spring stainless steel minimises blade end    leakage
• Interlocking blades ensure rigidity and tighter close-off seal
• Ground stainless steel blade axles and Oilite bearings reduce friction and torque requirements, thus smaller actuators
• Rigid galvanised steel construction resists  corrosion and extends damper life
• Corrosive-resistant internal blade linkage allows easy maintenance and field adjustment and interchangeable components
• High temperature silicone rubber for smoke control operation at 200 degree C on ultra-low leakage dampers
• Low leakage results in energy saving
• Tested to AS 1530.7 on 19th June 2007
