ET 512 Air Compressor Test Unit Show data sheet (pdf file) Print page
Technical Description

The experimental unit contains all the essential components of a compressor system.

  The compressor to be tested is a single-stage single-cylinder machine. During the functional test the efficiency of the compressor is investigated against the increasing pressure in the tank over time.

  The active power of the drive motor is displayed on the switch cabinet. A stopwatch is supplied for time-related measurements.


Learning Objectives / Experiments

Functional test of a piston compressor
- Pressure rise in the tank as function of time
