Door dampers function

How do door dampers work?

Door damper function 1

Door dampers are usually mounted centered below the upper edge of the door. The hook is placed above the damper on the door frame. When the door opens, the hook pushes the roller lever downwards, which tensions the spring in the door damper.

When the door closes the hook brings the roller lever upwards into position and the door movement is hydraulically dampened. All DICTATOR door dampers feature a progressive damping. This means that they control the door reliably and gently independently from door size and weight and whether the door is closed normally or slammed shut.

Then, the door damper draws the door completely shut and the force of the spring keeps it closed.

What are door dampers used for?

Leise

Doors can be incredibly noisy. Not only when people slam them, but also due to air pressure, gusts of wind and inadequate door closers. The more violent the  movement, the louder the bang. Doors that are protecting  all those who live and work within hearing distance of a closing door.

Tür Schaden

Furthermore a door check protects the door, the hinges and the frame. The door check functions quietly and reliably. Every time the door is slammed it catches the door without making noise, slows it down gently, pulls it firmly closed and reliably keeps it closed.

Energie Sparen

The door check not only reduces noise and prevents damages of the doors. Very often it helps towards saving expensive energy because the doors are really closed and thus the precious warmth or cooled air can’t escape.

Sicherheit

Last but not least, it provides safety as entrance doors of e.g. appartment blocks or office buildings are reliably closed.

Adjustment of the closing speed

Door Damper Adjustment

The speed of door dampers can be easily adjusted to your requirements:

  • Turning the piston rod clockwise reduces the damping speed
  • Turning the piston rod anti-clockwise increases the speed: Two complete turns are equivalent to a change of approx. 1 second
