Vacuum Sealing Machines remove the air from a bag and sometimes replace it with inert Nitrogen gas then hermetically seal the package to give long-term oxygen free protection to the contents. Conservation By Design has been the leading supplier of Vacuum Sealing Machines and Barrier Products to the Conservation profession for many years. They are widely used for numerous applications as noted below. All of these machines are fitted with a unique exhaust that allows extraction of potentially dangerous mould spores when dealing with old or wet books and documents.
