Oceanic Alpha 9 CDX-5 Regulator

With the Alpha 9, you get effortless breathing in a compact design.

It 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.
