Product Information
The Scubapro AIR2 5th Gen Inflator Regulator is a combination backup regulator and BCD power inflator in one compact unit, built for recreational and technical divers who want their alternate air source always within reach. It integrates with a BCD's buoyancy control system, keeping air within easy reach, and weighs about 1 lb. It is now in its fifth generation, keeping your alternate air source within reach when it is needed.
Who it is for
This is for the diver who wants to simplify the front of the rig: instead of a separate octopus clipped off plus an inflator, the AIR2 puts both functions in the same hand. The activity rating covers recreational and technical diving. It is also a direct choice for divers already running a Scubapro first stage who want an inflator reg that Scubapro itself documents in combination with that first stage.
Key details
- Inflator reg: backup second stage and BCD buoyancy control in one at-the-ready unit.
- Fifth generation of the AIR2 inflator reg, which combines a backup regulator with BCD buoyancy control.
- Large inflate and deflate buttons differentiated by color and by touch, so they can be identified by feel during an ascent.
- Fits comfortably in the hand as a BCD power inflator.
- Product weight: 1 lb. Scubapro part number 21.090.000.
Compatibility and sizing

Frequently Asked Questions
Which Scubapro first stages is the AIR2 5th Gen declared with?
Scubapro has issued EU Declarations of Conformity for the AIR2 (5th Gen) in combination with the MK11 EVO (2024), MK17 EVO2 (2024), MK19 EVO (2020), MK2 EVO (2020), MK25 EVO (2025) and MK25 EVO Titanium (2020). Archived declarations also cover combinations with the MK11, MK17 EVO, MK2 EVO, MK21 and MK25 EVO variants, dated 2019 to 2021. Contact us if your first stage is not on that list.
Does the AIR2 replace my octopus?
Yes, that is the idea behind an inflator reg. The AIR2 combines a backup regulator with your BCD's buoyancy control system in one compact, at-the-ready unit, so your alternate air source sits where your hand already goes for buoyancy adjustments rather than on a separate hose. It is now in its fifth generation and keeps your alternate air source within reach when it is needed.
How do you tell the inflate and deflate buttons apart underwater?
The AIR2 uses large inflate and deflate buttons differentiated by both color and touch. Combined with a shape sized to sit comfortably in the hand, that makes buoyancy adjustments and a controlled ascent more straightforward, which is the main safety argument for an inflator reg.
What is the Scubapro part number and weight of the AIR2 5th Gen?
This AIR2 5th Gen Inflator Regulator carries Scubapro part number 21.090.000 with barcode 4048336290500, and the published product weight is 1 lb. It is rated for recreational and technical diving. If you need help confirming fitment with your BCD, call our Irvine, California shop at 888-701-4017.
Review summary
Written reviews are still few for this one, so there is not much diver feedback to go on yet.

It integrates with a BCD, weighs about 1 pound, and carries MPN 21.090.000. Scubapro lists it for recreational and technical diving, so it suits divers who want to simplify their alternate air setup.
