Once the user ticks the chosen material and the blade/s, and enters the requested airflow and the requested static pressure in the dedicated blanks, the software will automatically show the list of impellers which meet the requirements. The user is free to decide whether to enter the impeller diameter and/or the rpm, or they can tick the free diameter and/or free rpm boxes.

When airflow and static pressure are unknown, the user can manually enter the diameter and the rpm, and leave the requested airflow and static pressure sections blank. The software will plot the performance graphs of the entire family (full range of angles) of the selected impeller.
