Saati Magi Vac Nozzle - This is a vacuum attachment for a standard wet shop vacuum. It is used to clear out the stencil after washing it out. This will eliminate the possibility of having under cured emulsion scum or film fill the open stencil areas after wash out. This tool can save a lot of time on press by making sure the finished screen and stencil is clean and clear, ready to go to printing. The heavy-duty, cast-aluminum nozzle is virtually unbreakable. 8-inches wide (20.32 cm). Fits most comercial wet/dry vacs.
