Why does vacuum and protective gas play an essential role in food packaging? Both are used to extend the shelf life of food. Protective gas like oxygen for example, needs special handling during the packaging process because it highly increases flammability. The new vacuum pump U5 series has been developed in regards to the special requirements of the packaging industry. In direct comparison to competitors the new U-series does not only have the best-in-class performance curves, but also innovative detailed solutions. For example; in the protective gas variant called MAPack, (Modified Atmosphere Packaging.) This new version makes the competitors external oil retrieval separators unnecessary. The patented design of the oil container provides the ground floor for a consistent design. This design allows for a smaller footprint thanks to the newly added integrated oil trap. This leads to better options for machine manufacturers, allowing easy integration into their systems.
