Questions and Answers for Aqua Lung Airsource Power Inflator Octo:

  • Ralph:

    I would like to know if Mfg Part Number : 15230 Aqualung alternate/ inflator comes with the corrugated hose and MP air hose as it is pictured

    Bill  (Certified Scuba Instructor at

    Yes this is the complete unit.

  • Imad:

    What do you need to connect the aqualung airsource to my cressi travel light bc

    Darrick  (Certified Scuba Instructor at

    Hello Imad, this would not work for the Cressi travel light. The BCD connections are different sizes and the corrugated hose is to big for the Cressi. If you are looking for a set-up like that. Then you need to look at the Atomic SS1 octo/power inflator. If you have any other questions please feel free to give us a call at 1.800.347.2822.

  • Lis:

    Hi, What do you need to connect the aqualung airsource to my aqualung zuma bc and my dive alert? Do I need an extra shorter hose? or maybe a flex hose? tks

    Clarke  (Certified Scuba Instructor at

    Hello Lis, Thank you for your inquiry! The AquaLung ZUMA BCD only need the complete AquaLung alternate air inflator Airsource. It comes with the longer corrugated manual inflator hose, the longer power inflator hose, the Airsource. Your original ZUMA power inflator unit/corrugated and power inflator assemble is unscrewed from the BCD and replaced with the complete Airsource assembly described above. If you would like to place an order or have questions about our products, please contact one of our certified Dive Instructors at by calling 800-247-2822 <> 949-221-9300 or e-mail us at:

  • Brian:

    Will this inflator/octo fit onto an Apex WTX-4 wing?

    Arthur  (Certified Scuba Instructor at

    No, this only fits seaquest/aqualung.

  • Larry:

    Will this fit on my Seaquest Explorer BCD.

    Bill  (Certified Scuba Instructor at

    This should fit but you might want to contact the manufacturer to make sure it is compatible.

  • Alejandro:

    I need to know if you can sell me the part No. 15240 of the airsource. I lost my BC but I stayed with the octo, so I only need the part that is attached to de BC. Thanks

    Bill  (Certified Scuba Instructor at

    Email for availability.

  • Calvin:

    Will this item work on an Aqua Lung Pearl BC?

    Arthur  (Certified Scuba Instructor at

    Yes, this will work with your BC.

  • Bradley:

    Does sell the adapter rings for the Airsource? Aqualung lists them on their site, but I can not find them.

    Darrick  (Certified Scuba Instructor at

    Hello Bradely, that is a part that supports a life support system. You would need to e-mail our repair dept. at They would be able to install this on your BCD.

  • Todd:

    I just picked up a Dimension I3 today. It still has the standard hose manual inflator but also the I3 inflation/deflation system. Would this work with that BCD? Would this replace or add to that system? I want to also use this as my alternate. Will these work?

    Bob  (Certified Scuba Instructor at

    Are you certain it has both? If it were to use both a traditional inflation system and the i3 inflation system it would require 2 separate power inflator hoses from the regulator 1st stage.

  • jeff:

    will this work on a aqua lung pro lt? thanks

    Bob  (Certified Scuba Instructor at

    This is designed to work with Aqua Lung and Seaquest BCDs

  • Randy:

    I dont think I need to ask this but this will work with the Aqua Lung SeaQuest Axiom i3. Right?

    Darrick  (Certified Scuba Instructor at

    Hello Randy, since the power inflator is built into the vest on the side this will not work for the I# version of the BCD

  • color:

  • Jorgen:

    Hi ! Will the ALAQO fit with my OMS wing BCD ? Br, Jorgen

    Darrick  (Certified Scuba Instructor at

    Hello Jorgen, no this will not attach the the bladder of OMS. They are different attachment.

  • Hollie:

    I just purchased a Cressi AirTravel 2.0 BCD and use an Aqualung Legend Regulator. Is there an adapter to attach the Airsource to my Cressi BCD for ease of travel and streamlining? Thanks in advance.

    Arthur  (Certified Scuba Instructor at

    This wouldn''t work with your BC and there aren''t any adaptors.

  • jim:

    will this work on a seaquest black diamond

    Darrick  (Certified Scuba Instructor at

    Hello JIm, yes this unit would replace your current set-up on your SeaQuest BCD.

  • Brad:

    Bob, can you elaborate on why it will not fit the Mares Hybrid? Looking at mine and my wifes hybrids (gen 1 & 2 respective) it looks like all the gen 2 needs is a bladder flange gasket and the gen 1 should fit no problem. They look to have the same threads and bladder flange shape (dodecagon). Thanks

    Bob  (Certified Scuba Instructor at

    According to AquaLung this is designed for AquaLung and SeaQuest bcd''s only. Most all other manufacturers, Mares included, do not recommend the removing of the inflation system from the shoulder attachment.

  • Michael:

    Do you sell just the hose for the Aqualung Airsource 3?

    Bob  (Certified Scuba Instructor at

    For parts or individual portions of the system please contact our instructors at

  • Chris:

    Will this fit my SeaQuest Pro QD

    Bob  (Certified Scuba Instructor at

    According to the manufacturer it will.

  • Ellen:

    Will this fit my Oceanic Kevlar Bioflex BC?

    Bob  (Certified Scuba Instructor at

    No. It''s designed to fit AquaLung/Seaquest bcd''s only.

The Airsource combines a high-performance second stage with a power inflator. By eliminating the need for a traditional octopus, the diver can streamline his entire system. In addition, unlike a traditional octopus that can drag in the sand or damage coral, you’ll take comfort knowing that the Airsource is right in front of you ready to deliver life saving air in a moment’s notice.

The mouthpiece has been upgraded to Comfo-bite and is much sturdier.  The MP hose has been upgraded to flexi hose which is lighter weight and more pliable.  The ribbed hose is softer making it easier to pull open the rapid exhaust valve at the top.  Both buttons are stronger and more durable.

The second stage valve is pneumatically balanced resulting in unparalleled performance and consistent breathing from start of dive to end.  Ideal for use with over-balanced first stages.  "Trim Grip" in the middle of the corrugated hsoe allows diver todump air from BC during ascent without removing the Airsource from the mouth.  Using a clever bayonet mount, the Airsource quickly and easily separates from the BC at the "Trim Grip".  This allows the Airsource to remain with the diver's complete regulator for packing and traveling.  Ergononomic design optimizes button placement for ease of use.  Soft-touch purge cover is located on the bottom so it won't be inadvertently activated in strong currents.  Low-profile, rapid-exhause valve is activated by pulling on the "Trim Grip" or the lower unit.  Corrugated hose has clips and recessed areas to accommodate the mp hose.
