  • Strip down and adjust PMV
  • Strip down and service Interstage condensate trap replace filter
  • Strip down and repack P21 filter
  • Adjust high pressure Oil Pump setting of Bauer final stage lubrication system.
  • Setup and use of Bauer B-timer Automatic filter monitor
  • Use of interstage pressure gauges for fault finding.
  • Test compressor to 330bars to confirm integrity and lack of leaks
  • Power consumption measurement – use of Voltmeter & clip on ammeter.
  • Rpm measurement methods
  • Heat measurement of heads and intercooler functionality checks
  • 3-phase wiring basics – Changing rotation direction of 3-phase electric motor
  • 3-phase star-delta starter / 6 wire 3-phase motor basics. Adjusting Star-delta switch time.
  • Petrol engine rpm regulator adjustment for correct rpm
  • Alignment of drive motor and fan belt adjustment
  • Pumping efficiency tests
  • Compressor Log sheets use
  • Introduction of faults to the compressor and technician booby traps
  • EN12021 Air purity testing – preparation and test workshop following rebuild


  • ASSET/IDEST approved Compressed Air Systems Maintenance Certification establishing the legal competent person status of the technician to work on all compressed air systems
  • All student training Manuals used during the course + online access to the technician database
  • All compressor spare parts & consumables used during the course
  • Free Tea/Coffee and high speed Wi-Fi internet access at the training center
  • There are no formal pre requisites for this course.

Key Benefits

  • Prevents costly damage to the compressor unit through lack of operator care
  • Prevents costly damage or destruction of the dive centers scuba tanks through the moistures damage resulting from the damp air supplied from an incorrectly cared for compressor
  • Provides proof of formal compressor and air bank training. When a new compressor stops working, manufacturers often blame the operator or the owner if the person responsible for compressor operation has no training. If the compressor operator has formal training, the blame for compressor failure shifts to the manufacturer or supplier of the unit.
