<strong>EDH</strong> <strong>28</strong> dampers are one-side operating<br />
hydraulic dampers for impact speeds up<br />
to 2,0 m/s.<br />
All <strong>EDH</strong> <strong>28</strong> dampers are produced with<br />
and without an overload safety valve<br />
(ABS). This anti-blocking device prevents<br />
the piston rod bending when the impact<br />
is too strong.<br />
Two different adjustment options are<br />
available; either adjustment screw or pull<br />
and rotate the piston rod. Make your<br />
choice considering ease of access and<br />
the possibility of unauthorized<br />
adjustment.<br />
After each damping an integrated spring<br />
returns the piston rod to its normal<br />
position. <strong>EDH</strong> <strong>28</strong> dampers can also be<br />
supplied with a magnet instead of the<br />
return spring. These dampers are<br />
particularly suitable for light sliding<br />
doors as they have no return spring that<br />
can slightly re-open the door.<br />
<strong>EDH</strong> <strong>28</strong> dampers are mainly used on<br />
sliding doors and in transportation<br />
systems. A special design with an excess<br />
pressure valve is available for use on fire<br />
protection doors (Certificate No. Do.11.3).<br />

<strong>EDH</strong> <strong>28</strong> <strong>Universal</strong> <strong>Dampers</strong><br />
With single fixing thread<br />
Fix the damper directly with its thread and the nut. Make sure that the direction of<br />
impact is parallel to the axis of the damper. A fixing block is available as an extra<br />
accessory.<br />
When choosing a damper with stepped adjustment (ZR), the damping force is simply<br />
adjusted by pulling and turning the piston rod. <strong>Dampers</strong> with screw adjustment (NR)<br />
are supplied with an adjustment screw at the top of the piston rod.<br />
A damper with two fixing threads should always be used with heavy loads.<br />

Fix the damper directly with the threads and the nuts. Make sure the direction of<br />
impact is parallel to the axis of the damper. The second thread ensures it is securely<br />
fixed, even when used with heavy loads. A fixing block is available as an extra<br />

<strong>EDH</strong> <strong>28</strong> <strong>Universal</strong> <strong>Dampers</strong><br />
With magnet<br />
<strong>EDH</strong> <strong>28</strong> <strong>Universal</strong> dampers with magnets are particularly suitable for light sliding<br />
doors, with no return spring to re-open the door. The piston rod is pulled back to its<br />
normal position by the magnet when the door is opened again.<br />
The damping force can be continuously adjusted by simply pulling and turning the<br />
piston rod.<br />
Use a steel plate to make contact with the magnet. We recommend our AP GD 50<br />
G16 counter plate - part no. 040 025. (Please see chapter 7<br />
page 07.041.00).<br />
Fix the damper directly with its thread and the nut. Make sure<br />
that the direction of impact is parallel to the axis of the damper.<br />
A <strong>EDH</strong>M damper with two fixing threads should always be<br />
used with heavy loads.<br />
A fixing block is available as an extra accessory (see diagram on<br />
page 03.016.00).<br />
