About Oceanic Alpha 9 CDX-5 DVT Regulator

The Alpha 9 CDX-5 features effortless breathing in a compact design that is extremely tough yet easy to maintain and service, and is paired with a compact over-balanced diaphragm first stage. The CDX5 first stage is made of Chrome Plated Marine Grade Brass and is a Balanced Diaphragm Design. With this design water doesn't enter the first stage, which means the CDX5 is excellent for ice diving (it won't freeze up) or diving in waters filled with contaminants or sediment (it won't corrode). Environmentally sealed, the diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. As is the Alpha 9 CDX-5, comes ready to use with air or nitrox mixtures up to 40 percent. Two high pressure and four low pressure ports assure a place for all your necessities and accessories.

The Alpha 9 Regulator Second Stage has a Patented Orthodontic Mouthpiece for exceptional comfort and Reduced Jaw Fatigue. The Mouthpiece accommodates the natural Overbite of the human jaw. In Addition the 30" (76.2 cm) Max-Flex Hose with its extreme Flexibility further reduces any Jaw Fatigue, making this one comfortable breathing regulator.

The Alpha 9 is classified as being suitable for use with nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts. Regulator weighs 35 oz (992.23 g) and the front profile dimension is only 2.9" (7.4 cm). Regulator comes with a Comprehensive Owner's Manual.

      Comments about Oceanic Alpha 9 CDX-5 DVT Regulator:

      I didnt even get into the water before the regs failed. The were free flowing constantly and couldnt ne stopped. Even though it was brand new they said i would be charged to fix the problem unless i returned it to the US where i ordered it from. Be very careful when buying Oceanic. They wont standby theur product. They will just tell you to read their policy
