The European EFA programme involves the production of certain aircraft parts with all its phases, including sanding and painting. The plant is also designed for the maintenance of aircraft parts and is therefore suitable for handling the stripping and repainting phases of the parts to be maintained. If products containing VOCs are to be used in this plant, it is equipped with a concentration absorption and regeneration system, all managed with intrinsic safeties that prevent the plant from operating if the purification process is not active.
