About this app
VacuumProjectPro is an engineering application dedicated to calculations for vacuum technology. It calculates fundamental vacuum-system parameters, including pumping speed and pump-down time for primary and secondary vacuum systems. VacuumProjectPro uses pumping-speed curves for different vacuum pump technologies—including single-stage and two-stage rotary vane pumps, Roots pumping systems and turbomolecular pumps—to calculate operating parameters using integral calculations. PRO version features: - PNEUROP pumping-speed calculations for primary vacuum pumps, including single-stage and two-stage rotary vane pumps and Roots systems - Primary and secondary vacuum calculations - Vacuum chamber leak-rate calculations - Conductance calculations for tubes and tube series - Effective pumping-speed calculations - Outgassing calculations for a wide selection of vacuum materials, including custom materials - Unit conversions for pressure, leak rate, pumping speed and other vacuum quantities - Catalogue of ISO-KF, ISO-K and CF vacuum components - Optimized graphics for Retina displays - Additional engineering tools and reference information IMPORTANT NOTICE VacuumProjectPro is an engineering calculation and simulation aid. Results must be independently verified before being used for the design, selection or operation of vacuum systems. The app does not replace professional engineering judgment. The authors accept no responsibility for errors, improper use or consequences arising from the use of the calculated results.
