The floor spring WAB 180 has been proving its value for many decades. It was developed as early as 1950 and remains just as irreplaceable today as it was then.

Thanks to our modern production facilities, it has now been given a facelift, which further enhances its strengths with the aid of new technology.

What makes the WAB 180 unbeatable?

• Since the facelift, the housing is made of aluminum and no longer of sand casting. It is completely manufactured in our Berlin production facility with our own machines, which leads to even more flexibility, accuracy and stability.
• The complete interior of the floor spring is filled with oil. This ensures constant damping at all times. It also prevents leaks from happening on the brake cylinder and keeps the axle bearings, which easily support doors up to 600 kg, constantly lubricated so that it never runs dry.
• A two-stage sealing system is now used to seal the axis: a shaft sealing ring in the housing and an additional axial seal on the shaft. The axial seal protects the actual seal, especially in case of use of sharp cleaning agents or similar substances.
• A larger clearance has been added around the heads of the regulating screw and oil filler screw so that any contamination can be easily removed before opening them. Furthermore, the hole in the cover plate above the regulating screw is additionally sealed with a plastic cap to protect the screw from dirt.
• In the new embedding box, there are two weld-on bolts at the bottom to which the WAB is screwed. This simplifies its installation, as it automatically positions the floor spring correctly in the box.

Replacement housing

Even though the floor springs WAB 180 are known for their extremely long service life, a replacement of old closers may be necessary at some point. The dimensions of the new WAB 180-2 are slightly different from those of the previous version with cast housing and the new closer will therefore not fit into an existing embedding box.

However, to make the replacement as smooth as possible, the WAB 180-2A is supplied with a housing specially adapted to the old embedding boxes for replacement purposes. This version can be installed in the embedding box of the old WAB 180 without any problems. Also the existing cover plates can still be used.

DICTATOR gas springs and oil dampers have been making our lives easier for almost 50 years now. They ensure a safe motion sequence in a wide variety of applications, such as flaps and other moving elements, as well as providing a comfortable operation.

Our many years of experience in calculating the perfect gas spring and oil damper and their fixing points together with flexible and highly efficient manufacture in Bernau, near Berlin, guarantee that you always receive a solution perfectly tailored to your need, even for small quantities or single units.

We look forward to offering you even more possibilities for the design of our gas springs and oil dampers from January 2021 on!

DICTATOR gas springs and oil dampers will be supplied with a painted finish from January 2021 onwards

Thanks to our new, state-of-the-art paint shop, we can now deliver our gas springs and oil dampers painted (standard color in RAL 9006, white aluminium) starting with the New Year. The main advantages:

• The painting allows for higher flexibility in the production process. This will lead in the mid-term to a further reduction of the already short lead times.
• Since the cylinders have no longer to be sent out to be galvanized we help avoid unnecessary transportation routes, thus contributing to environmental protection.
• Painting offers more possibilities to match the gas spring / oil damper even better to the application, since they can be supplied in a wider variety of colors.
• The painted surface offers excellent corrosion protection, as proven by salt spray tests in accredited testing laboratories.

Which products will be delivered with a painted cylinder from January on?

• Push type gas springs of the ranges 6-15, 8-19, 10-23, 14-28, 20-40
• Gas springs with floating piston of the ranges 8-19, 10-23, 14-28
• Locking gas springs (rigid and cushioned)
• Pull type gas springs (normal and short) of the range 10-28
• Variable speed gas springs
• Preset oil dampers of the ranges 6-19, 8-23, 10-28, 14-40
• Adjustable oil dampers of the ranges 10-28, 14-35 & 25-69

Gas springs/oil dampers that have to be shipped via our express service within 3 working days and our next-day overnight service will still be delivered galvanized, as the paint requires more hardening time to ensure optimal corrosion protection.

Gas springs/oil dampers with protective tubes will also continue to be manufactured galvanized until further notice, since durability tests still have to be carried out.

Digital media – a good add-on, but no substitute for expert customer support

For the selection of the most suitable gas spring, we strongly believe in individual customer support, because only by examining an application on an individual basis can we ensure that the gas spring meets all requirements and functions reliably. This is shown by the following example of a floor flap:

The requirements for the flap were that it should open on its own after being lifted slightly and that it should remain securely open, since falling shut would pose an enormous hazard. It also had to be possible to close it again by hand without great effort. In addition, the gas springs had to be installed in a way which didn’t restrict the already narrow access to the stairway any further when the flap was open.

Many years of experience, a specially developed calculation program, and the thrill of each new challenge ensure that we can find a suitable solution even in such cases. Determining the right gas springs and fixing points for your application is always included in our service. The advantage: You can be sure that everything will work perfectly in the end.

Our technical staff will be happy to personally assist you with your projects. They will support you from the planning stage and selection of the right product to proper installation.
