Vacuum Sprinkler System （Dry Type）

Piping: negative pressure air

• Prevents Leakage Accidents
  Making negative pressure air instead of water to prevent leakage.
  This allows for easy replacement of sprinkler head without stopping the water flow.

• Ensuring Safety During Discharge 
  Since the pipe is negative pressured, air compression is minimized during water filling in the pipe.
  It prevents parts flying off or fire spreading due to the high-pressure air when the sprinkler head activates.

• Enables Quick Discharge 
  Negative pressure allows for quick filling and discharge.

• Reduces Pipe Corrosion 
  Negative pressure dries the inside of pipes and minimize corrosion.

 Vacuum Sprinkler System （Wet Type）

Piping: negative pressure water

• No Water Discharge in Damage 
  When the head is damaged, outside air is drawn in and no water leaks occur.
  This allows for easy replacement of the head as well.

• Covers in case of Freezing Damage 
  Prevents water leak after the ice melts when pipes are damaged by freezing.

• Keeps Dry with Pinholes 
  No water leaks out even pinholes occur.

• No Abnormal Pressure Rises 
  Negative pressure monitoring prevents abnormal pressure rise.

• Reduces Pipe Corrosion 
  Negative pressure reduces the amount of dissolved oxygen in the water, reducing pipe corrosion.
