SMOKE DAMPER WITH MICRO KIT

Technical Features

• Model

  Smoke damper with micro kit, various sizes

• Characteristics

  MAIN FEATURES:
  They are operated by an electric motor and can assume two operating positions depending on whether the motor is activated or not. The tube and shutter are made of stainless steel. An auxiliary switch is mounted on the motor mount, which is activated when the damper is switched on. The damper is equipped with an external lever for manual positioning of the shutter, which also serves as a position indicator. These dampers are used as flue gas shut-off valves in the chimney of gas and oil boilers. They can be installed both vertically and horizontally.
  
  
  OPERATION:
  Without power, the valve positions itself with the butterfly valve open. When power is applied, the servomotor overcomes the force of the springs and rotates the butterfly valve, thus closing the passage and holding it in that position until the power is removed. When the power is removed, the return springs reopen the passage.
  
  AUXILIARY SWITCHES:
  In all versions, a unipolar (M1) or bipolar (M1S) auxiliary microswitch is also available.
