VHP and isolator engineering calculators
Free calculators for the numbers that come up when planning and testing VHP bio-decontamination. Each tool shows its method and limits, and you can send any result to a Fenggu engineer for review.
ISOLATORS · CALCULATOR
Isolator leak rate calculator
Pressure decay reading → hourly leak rate and ISO 10648-2 class, with temperature correction.
Open the tool →SAFETY · CALCULATORVHP aeration time calculator
Volume, starting ppm and airflow → ideal time to reach 1 ppm (or your own target), with a log-scale curve.
Open the tool →EQUIPMENT · CALCULATORVHP equipment selector
What you need to treat and how big it is → the type of VHP equipment that fits, and what to confirm.
Open the tool →All results are engineering estimates. Cycle times, leak-tightness and efficacy are confirmed by testing and validation for your equipment and load.
