I'm looking for a solution for passing product from a clean room production line to an 'outer clean room' where the product is packed into cardboard boxes. I need to have flexibility in the position of production lines. The simpliest way seems to be cutting out a pass though in the wall, but if I need to move the lines in the future I'm restricted to where the cut outs are. Ideally if there was a section of the wall cut out the full length of the clean room I could move the lines wherever I wanted, but that's not practical, or is it?? Ideas welcome!
