BLS movable soundproof wall

Semi-automated version – the most important details

In order to achieve a comfortable setup and removal of the individual elements, the movable wall can be realised in a partially automated or semi-automated manner. Here, the upper and lower sealing bars as well as the lateral sealing of the element are extended and retracted by means of individual motors and spindles.

There is no manual extension and retraction by means of a crank handle; nevertheless, this is still possible in the case of an electricity failure.


The semi-automatic operation is activated by a key switch.
The electrical supply for this is to be provided by the customer.

The sealing bars of the elements are automatically pressed towards the ceiling and the floor by spring forces.


The sealing bars are driven by a powerful 24 volt electric motor.

The contact unit between the individual elements is embedded in vertical profiles.
