Dirty Air Probe (DAP) Test System | Airflow Sciences

The dirty air pitot (DAP) probe is utilized to measure air velocity, pressure, and temperature within a flow stream that is heavily laden with particulate. Compared to other pressure-type velocity probes, the design of the DAP reduces the potential for pluggage of the pressure lines, a situation that will yield erroneous results.
