Pressed pneumatic realized for being used in coupling to ransom filters Multifilter, with little simple operations and fast the volume is diminished of the leaking parts of the 50 70%, and are extracted compressing it residual oil from the material leaking for an ulterior one weight saving. Saving ulterior of volume and depended that it is transformed in a gain sure for the operator. the pressed one posiziona over to Multifilter without ulterior it blocks, so as to to render the maximum with zero I block
