Assembling giant vacuum wall

Months ago i agreed on designing and manufacture a 2100x2500 vacuum wall for Norwegian artist pushwagner´s photo studio.
After producing the technical drawings, the contract was signed, and the product taken into production at Fellesverkstedet

Below are som photos from the production of the vacuum wall.

The vacuumwall must be adjustable. Therefore, mechanical valves where added in form of PE slides.
As a consequence of this, the vall became very thick, and several hundred screws had to be used to keep it from imploding from the underpressure.

This is one of the two halves making up the vacuum wall under assembly.

Here, the two halves of the vacuum table stands ready for delivery and mounting at the customers photo studio:
