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 enabling smaller actuators
• Rigid galvanised steel construction resists corrosion and extends damper life
• Corrosive-resistant internal blade linkage allows easy maintenance and field adjustment
• Clip-on design of seal allows field retro-fit
• Ultra-low leakage results in energy saving
