What calculation tools should be used to correctly size an industrial or laboratory ventilation system?

---

Why calculation tools have become indispensable

In industrial and laboratory ventilation projects, decisions are based on:

• precise airflow rates ,

• controlled pressure losses ,

• justified technical assumptions .

Approximations lead to:

• underperforming facilities,

• excessive energy consumption,

• regulatory non-conformities,

• costly rework during the operational phase.

👉 Calculation tools help to make decisions more reliable from the very beginning of the project .
