Centrifugal fan test unit

DESCRIPTION

The centrifugal wind tunnel test unit is complete with instrumentation and includes a technical and instruction manual.

The aspiring flue and fan can be disconnected and operated independently.

The components of the unit can be disconnected from each other allowing for many different designs in specific investigations.

Open circuit.
