DL3/4 are Replaced by DS3/4.

From May 2023, the station designation DL3/4 will be replaced by DS3/4.

The double stations are 1:1 interchangeable, as they are identical. Technically, they only differ in the mesh size of the filter.
In future, both filter variants will be available with the designation DS3/4.

As a result, we are reducing the complexity of our product portfolio and are faster in processing.
