Oceanic FDXi Regulator, First Stage (Only)

The cold forged, over-balanced diaphragm FDXi First Stage is environmentally sealed. The in-line design limits the pressure loss inherent in "L" type first stage designs making the FDXi more efficient and lighter due to its compact form.

The FDXi offers a balanced diaphragm. The balanced diaphragm is inherently environmentally sealed. Water enters the main spring cavity and the pressure increase from the water is transmitted to the internal components by the impermeable diaphragm membrane. The benefit of this type of first stage design is that none of the delicate internal parts are exposed-to-contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants can cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. A diaphragm first stage regulator requires less-maintenance then regulators that allow these contaminates to enter the internal mechanism.

In addition the FDXi first stage regulator has a secondary diaphragm to completely seal-off the main spring cavity. A sealed balanced diaphragm design; Enviro Kit and patented DRT (Dry Regulator Technology) isolate the main spring cavities internal components from the environment. It also means the FDXi is excellent for ice diving (it won't freeze up) or diving in waters filled with contaminants or sediment (it won't corrode). At 21 oz. (595.3 g), the FDXi is Oceanic's lightest weight first stages. The FDXi first stage has 2-high pressure and 4-low pressure ports assure a place for all your necessities and accessories. The FDXi is Nitrox ready up to 40% out-of-the-box.
