The Eurodib Atmovac Gas Flush Kit M52-II Complete (0903036) is an accessory designed to enhance the functionality of the M52-II vacuum packaging machine, also known as the CY20 model. This gas flush kit allows users to incorporate gas flushing capabilities into their vacuum packaging process, which is particularly beneficial for extending the shelf life of perishable goods. By replacing oxygen with inert gases such as nitrogen or carbon dioxide, the gas flush kit helps inhibit the growth of aerobic bacteria, mold, and other microorganisms, thereby preserving the freshness and quality of packaged items for longer periods.
