Newly designed concept with a so called "transfer" (roll on / roll off) work area (body tray), which is equally used as a body tray. The upper part of the table is constructed like a large sink, where the body tray is transferred to. It contains a large drain sewer with a sieve. The bottom of the plenum has no opening for extracted air! At two sides of the walls of the plenum a double slot system was incorporated, which guarantees an effective ex- traction at both sides of the work area over the complete length of the body. The actual extraction is provided by an external fan system or an in-house extraction system.
