Eurovac has 50' x 3/8" flexible air lines available for hooking into the existing hard pipe on the wall or the existing inlets on the wall, with a quick disconnect. The air line is then run up the wall, and across and down to the hanging drop. It is secured to the piping or beams by tiewraps, provided by Eurovac. These air lines are available with single outlets for single workstations or double outlets for double workstations. The air lines come with 1/4" male threads on the workstation end, and the other end is left bare so you can cut the hose to length. A hose barb with a 3/8" male thread and hose clamp are provided for this end. The air lines include a grounding wire to convey any static electricity from the tool (which also includes a grounding wire) and vacuum hoses. The grounding wire is usually attached to the Eurovac piping or to the beams. The above method is inexpensive and functional, but lacks the "professional" quality of the method recommended for new shops (as outlined below).
