Features

• Spring stainless steel side seal minimises blade end leakage
• 9-breaks interlocking blades ensure rigidity and tighter close-off seal
• Ground stainless steel blade axles and ‘Delrin’ or Oilite (optional) bearings reduce friction and torque requirements, thus smaller actuators
• Rigid stainless steel construction resists corrosion in aggressive atmosphere and extends damper life
• Corrosive-resistant internal blade linkage allows easy maintenance and field adjustment and interchangeable components
• Clip-on seal (optional) allows field retro-fit
• Low leakage results in energy saving
