Evidence released from analysis of competitor’s vacuum flow data suggests it was mostly calculated using assumptions based simply on model size, not physics
Third party analysis of IVM’s main competitor’s vacuum performance data uncovered some troubling issues that question its legitimacy. This data, which for ~20 years has been considered to be representative of real physical test data, was shown to be calculable to an average error of ~ 0.1%, from a single equation. This is true across the entire vacuum range, regardless of ARV valve type or differences in internal geometry. This fact, combined with other physical inconsistences, has started to cause major engineering companies who depend on the implied legitimacy of this data to re-evaluate ARV purchasing practices, to the advantage of Vent-Tech®.
