Oceanic CDX5

Oceanic CDX-5 Compact Balanced Diaphragm First Stage 

The CDX-5 Balanced Diaphragm First Stage is the perfect regulator for extreme diving conditions, such as ice diving or diving in high sediment. The balanced diaphragm first stage design has been the regulator of choice for many divers who find themselves pushing the envelope. The advanced design of the CDX-5 isolates the critical seats and o-rings from the harsh environment. This helps prevent internal corrosion and contaminant buildup, leading to more consistent performance between service intervals.

The CDX-5 high performance over-balanced first stage provides progressively greater intermediate pressure as depth and gas density increases. The center “pads” that the diaphragms act against are different sizes so the working area of the outer environmental diaphragm is larger than the working area of the inner diaphragm. As depth increases, more pressure is applied to the larger surface area of the outer diaphragm than would be applied to the internal diaphragm. The result is superior gas delivery under the most extreme conditions
