Our airflow test stands were the first in the industry to offer test equations for multiple manufacturers. Flow test sequences, called "circuits" can automatically flow air with multiple test steps and with various airflow equations (i.e. specialized reduced airflow measurements)

Ideal for testing cooling holes of Turbine Engine Blades, Vanes, Shrouds, Combustors, Nozzles, and Buckets.
