Regulator Seminar

Posted on by bjornloftisdiving

Hi Equipment enthusiasts!

I’m proposing a regulator seminar for divers with an interest in getting the most out of their equipment.

Please note:  This is not a PADI certification class.  You will not receive a C-Card for attending.  Also, this a not a manufacturer’s regulator repair class.  It will not qualify you to overhaul your first or second stage.

This seminar will focus on theory and practical skills that will enhance your understanding of your regulator, its use, and typical repairs that are within the skill of any diver.

There is some overlap of the content of this seminar with the PADI Equipment Specialist class – so your participation at this seminar may be credited towards satisfying some of the requirements of a PADI Equipment Specialist.

 

Regulator Seminar:

  • Brief History of Regulators (10 minutes)
  • Overview of Regulator Function (10 minutes)
  • Focus on First Stages (90 minutes)
    • First Stage Function:  How to create Stable IP (Intermediate Pressure)
    • Pressure compensation of IP
    • Piston versus Environmentally Sealed Diaphragm
      • Design and Operation
      • Functional Differences
      • Advantages and Disadvantages
    • Unbalanced, Balanced, Overbalanced
    • DIN versus Yoke
    • Other Features:  Ports: HP, LP, High Flow LP, Turrets, Swivels
    • Disassembly to Illustrate Function
      • Scubapro Mark 2 (Unbalanced, Piston 1st Stage)
      • Scubapro Mk17 (Overbalanced, Diaphragm 1st Stage) or Hollis DC1
    • Student Exercise:  Measuring IP with an IP gauge and what it tells us about our first stage’s health.
  • Focus on Second Stages (90 minutes)
    • Second Stage Function:  Ambient pressure from Stable IP
    • Balanced versus Unbalanced
    • Venturi Assist (Dive / Predive)
    • Cracking Pressure Adjustment
    • Disassembly to Illustrate Function
      • Scubapro R195 (Unbalanced 2nd Stage)
      • Scubapro G260 (Balanced 2nd Stage)
    • Student Exercise:  Measuring Cracking Pressure on a Magnahelic.
  • Service Technicians Role:  (Frequency of Service, Tools, Training, Process, Liability)  (10 minutes)
  • Hands on Clinic on appropriate Regulator Repairs:  (30 minutes)
    • Discuss limitations and liability for people NOT trained by the manufacturer for service
    • Student Exercise:  Proper care and storage.  Rinsing of regulator, inspection of fittings under strain reliefs
    • Student Exercise: Diagnosing Leaks (HP / LP Hose, Plug, Spool, o-ring, etc.)
    • Student Exercise: Appropriate Tools, Lubricants, techniques.
    • Student Exercise: Installing Accessories (Hose, Plug, Spool, SPG, Computer Transmitter, 2nd Stage)
    • Student Exercise: Inspecting / Installing a mouthpiece
