HAHN Gasfedern SDD sliding door damper, soft closing of 40–400 kg leaves

The HAHN Gasfedern Sliding Door Damper (SDD) is designed for heavy doors, windows and pull-out sections moving in a straight line. One component combines three functions: damped approach to the end stop, degressive braking and soft closing.

The unit combines two gas springs and an oil brake and smoothly absorbs the mass at the end position. The working range is 40 to 400 kg, most typical for leaves from 100 kg. Supplied in series batches, selected according to leaf mass.

Key features:

• Three functions in one unit: approach, braking, soft close
• Calm movement on leaves heavier than 100 kg
• Degressive braking — no impact at the end
• For doors, windows and industrial pull-out modules
