Questions and Answers for Aqua Lung Airsource 3 FCD (Freeflow Control Device) Octo:

  • Mark:

    I have a new AquaLung Dimension i3 and Mikron regulator with no alternate air source yet. Can I use the Airsource 3 with the i3...and does it make sense, rather than buy a separate alternate?

    Hello Mark, since your power inflator is build into the bcd in the bottom left side you would not be able to use this as a alt air source. You would not be able to connect this to your BCD since there is no connection at the top left of that BCD. You would need to go with a Octo on your right side.

  • Rod:

    Aqualung website says an adaptor ring is available for its Airsource 3. Can you supply the adaptor ring along with the Aqualung Airsource 3 and if so how much is it complete.

    We only carry the complete units with quick disconnect or flow control devise. These only fit Seaquest BCs.

The Airsource 3 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 3 is right in front of you ready to deliver life saving air in a moment's notice.

Several new features have been added to this latest version of Airsource to make it the most desirable of all breathable inflators.

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

Redesigned 'Trim Grip' in the middle of the corrugated hose allows diver to dump 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

Rather than use a traditional quick disconnect fitting, the Airsource is connected via a hose like your primary second stage. This allows better flow and better performance. It also prevents particulate matter and moisture from entering the second stage

A specialized cut-off valve allows the diver to quickly and easily shut off air to the unit should there ever be a malfunction

Ergonomic 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-exhaust valve is activated by pulling on the 'Trim Grip' or the lower unit

Corrugated hose has clips and recessed areas to accommodate the lp hose

Easier to service than it's predecessor

Available for shipment to U.S. zip codes only
