Aqualung Calypso Regulator

The Aqualung Calypso Regulator, Aqualung is proud to introduce the fifth generation Calypso regulator! This simple design, with its attractive price, makes this regulator a popular choice for new divers. It is compact, lightweight and it breathes like a regulator that costs much, much more.


First Stage:

  • In-line, high-flow piston design means fewer components, excellent reliability and easy maintenance
  • Large diameter of piston guarantees a more stable medium pressure output
  • The 6 large holes in the end cap results in easier cleaning as well as better thermal exchange, thus improving the freezing resistance
  • Features 1 HP port and 4 MP ports
  • Compatible with EAN 40 new, out of the box


Second Stage:

  • Mid-size, high performance, demand valve second stage
  • The easy-to-grip venturi lever prevents unwanted freeflow at the surface while giving a performance boost at depth
  • Can easily be reversed from right-handed to left-handed configuration by an Authorized Aqua Lung dealer without additional parts
  • Comes with Aqua Lung’s Comfobite™ mouthpiece that reduces jaw fatigue
  • A grid built into the exhaust tee creates finer exhaust bubbles for less noise and more stability
  • Easy purge front cover
  • A reinforced polycarbonate material makes this second stage stronger than its predecessor
  • The side openings on the front cover prevent freeflow when facing into currents or riding a scooter



  • Number of HP ports: 1 - 7/16 UNF
  • Number of MP ports 4 - 3/8 UNF
  • Flow rate 1300 ltr per min @ 200 bar
  • First stage exterior: Chrome over marine brass
  • Controls: Venturi switch
  • Mouthpiece: Comfobite
  • Overall work of breathing (WOB) scores Avg. 1.05 joules/liter @ CE parameters
  • Nitrox compatible: Yes to 40% O2 when new, out of the box
  • Certification EN250 approved
