Duct Calculator

The S&P duct calculator allows three different calculations to be carried out quickly and with ease. These calculations are divided into four areas:
1. Diameter converter, which converts circular diameters to equivalent rectangular ducts.
2. Ventilation parameter calculator allows the diameter, air speed, airflow and dynamic pressure of your installation to be calculated.
3. Pressure drop calculation tool for installations with straight sections and duct system elements.
4. Units converter, with which you will be able to transform speed, airflow, power and pressure units into other units of measure and scales.
