Product Information
The Aqua Lung Airsource Dive Regulator is a combination alternate air source and BCD power inflator that replaces a traditional octopus with a single unit mounted on the front of your BCD, where you can reach it immediately. It pairs a pneumatically balanced second stage with a breathable power inflator, and it detaches from its bayonet mount at the Trim Grip for travel.
Who it is for
This is for recreational divers who want their backup air source positioned where it cannot dangle, drag or go missing, and for divers who prefer to carry fewer hoses and less clutter on the front of the BCD. It suits traveling divers because the Airsource separates from the BCD at the Trim Grip and packs with the rest of the regulator set, and it is a good match for divers using over-balanced first stages, since the second stage is pneumatically balanced for consistent breathing throughout the dive.
Key details
- Dual function: high-performance second stage plus BCD power inflator in one housing.
- Pneumatically balanced second stage for consistent breathing effort through the dive.
- Trim Grip in the middle of the flexi-hose dumps air from the BCD during ascent without removing the mouthpiece.
- Lightweight flexi-hose that is softer and easier to pull to open the rapid exhaust valve, with clips and recessed areas to route the MP hose.
- Soft-touch purge cover on the bottom of the housing to prevent accidental activation in strong currents.
- Bayonet mount connection to the BCD for quick removal.
Compatibility and sizing
The Airsource attaches to a bayonet mount on the BCD and separates from that mount at the Trim Grip, so compatibility depends on your BCD's inflator and mount configuration. If you are not sure whether your BCD accepts the Airsource, contact us before ordering and we will check it with you. This item is supplied under part number RG147111.

Frequently Asked Questions
How is the Airsource different from a traditional octopus?
A traditional octopus is a separate second stage on its own hose, routed apart from the inflator. The Airsource replaces it by combining the second stage with your BCD power inflator in one unit mounted on the front of the BCD. That keeps the backup air source in a known position directly in front of you, removes a dangling hose and simplifies your front profile.
Can I still deflate my BCD while breathing from the Airsource?
Yes. The Trim Grip control sits in the middle of the flexi-hose and lets you dump air from the BCD during ascent without taking the mouthpiece out. The flexi-hose is lighter and softer, so pulling it to open the rapid exhaust valve takes less effort.
Will the Airsource fit my BCD?
The Airsource connects to a bayonet mount on the BCD, so fit depends on your BCD's inflator and mount setup. Because the manufacturer compatibility list is not published here, contact DiveCatalog.com with your BCD model and we will confirm whether the Airsource can be installed before you order. Call 888-701-4017 or use chat.
Is the Airsource practical for dive travel?
Yes. It separates quickly from its bayonet mount on the BCD at the Trim Grip, so you can remove it and pack it together with your complete regulator set instead of leaving it attached to the BCD.
