AURVTN033 Service and repair air compressors and components
Assessment tool
Version 1.0 Issue Date: May 2024
This unit describes the performance outcomes required to test, service and repair air compressors and associated components. It involves preparing for the task, cleaning and replacing filters, making adjustments and necessary repairs according to workplace instructions, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The compressors are for workshop air supply, drilling rigs or mobile compressors. This unit is not for air brake compressors on heavy vehicles.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the air compressors that they have serviced and repaired, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive workplace or simulated workplace
workplace instructions
manufacturer air compressor specifications
two different operating air compressors and components as specified in the performance evidence requiring service and repair
tools, equipment and materials appropriate for servicing and repairing air compressors and components.
