Product Information
An inflator reg combines a backup regulator with a BCD's buoyancy control system in one compact, at-the-ready unit. SCUBAPRO introduced the inflator reg concept to diving almost 30 years ago with the AIR2 (short for Alternate Inflator Reg). Now in its 5th generation, the AIR2 delivers air as smoothly as most primary second stages, and unlike traditional dangling octos, it is always within easy reach if needed. As a BCD power inflator the AIR2 fits comfortably in the hand, and the large inflate and deflate buttons can be differentiated by both color and touch, improving safety on ascents. The AIR2 was diving's first inflator reg and, with five generations of improvements, it's still the best.

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
Reviewers consistently rate this gear five stars, and the recurring theme is how light and compact it is: several say it is compact and easy to pack for travel, and one reported more than 500 dives on the same setup still in good shape. Reviewers praised how it handles buoyancy control, and a couple found it comfortable in the water. A good pick for traveling recreational divers who want a compact, light setup.
