Axial fan test unit

DESCRIPTION

The axial fan test unit is complete with instrumentation and includes a technical and instruction manual.

The aspiring conduit and the fan can be disconnected from the rest of the unit and set up separately.

The components are easily separated allowing instructors to vary the design of specific projects.

Open circuit.
