• Test With Original Parts Schmalz

    Test with Original Parts. A complete and energyefficient vacuum system has been assembled from the Schmalz vacuum components. You should still conduct tests with original sample workpieces. The theoretical system design gives you a feeling for the size of the system. Schmalz has its own test center in which we conduct practical tests.
