G.P.A. pneumatic feeders, as all G.P.A. pneumatic equipments, completely match all the technical requirements of the EEC standards to day in force, particularly the "machinery" directive and the EMC directive, in some versions also for not protected dangerous areas.
G.P.A. pneumatic feeders work by diaphragm operated clamps; the movable clamp slides along two thickly chromed ground steel columns.
