AirflowPressurePro is a smart and easy-to-use app to help engineers and designers calculate airflow needs in tunnels and ventilation systems. It brings together key tools to manage air quality, fan performance, and safety with just a few simple inputs.

From estimating fresh-air demand and fan thrust to checking CO/NOx dilution and pressure balance, everything is quick and accurate. The app also helps analyse visibility, reversible flow, and cross-passage purging for better safety planning.

With its simple design and reliable results, AirflowPressurePro makes complex airflow calculations easy for everyday use. Our goal is to save your time, improve accuracy, and support better air control decisions.
