Omega 3

We've turned conformity on it's side… again.

Introducing the sleek new Omega 3 side exhaust regulator. Once again we needed to break a few conventions in order to provide the kind of performance we demand in our gear.

From the unique levered servo valve to the placement of the dive/pre-dive switch and the positioning of the side exhaust valve... everything has been considered. The Omega 3 is a daringly unique regulator design and a perfect example of how diver ergonomics and valve function can come together to produce a regulator that is far more superior than traditional designs.

A Daringly Unique Design

The core of the Omega 3 is its durable levered servo valve. Truly one of diving's most unique regulator valve designs. It delivers airflow that is proportional to your demand without the sudden rush of air at depth or fluttering when you're shallow. We accomplished this feat with an ingenious two-chamber balanced design that provides pressure assisted air-flow and near zero inhalation effort. Unlike other regulators, the Omega 3 has no need for an inhalation-effort adjustment knob.

The Omega 3 valve is constructed from a tough, corrosion-resistant chrome plated marine brass valve that has better cold water performance and all-round breathing experience than standard valve designs. The all-metal valve encourages condensation of water vapor from your exhalation on the valve housing. When you inhale, condensed water vapor circulates with the airflow and helps reduce "dry mouth" and increase your overall level of comfort. The servo valve also has no up or down, meaning that it's a truly ambidextrous breather. This design allows you to comfortably route hoses anyway you like and makes the Omega 3 a great choice in an emergency as an backup air source.

The positioning of the side exhaust valve is another example of purposeful design. Keeping exhaust bubbles out of your field of view is a huge benefit for all divers. Photographers and videographers however, will be especially thankful for the unobstructed views.

The Omega 3 second stage comes paired with our new first stage FDX-i. The cold forged, over-balanced diaphragm FDX-i is environmentally sealed. It's in-line design limits the pressure loss inherent in "L" type first stage designs making the FDX-i more efficient and lighter due to it's compact form.

These two innovative and high-performance designs combine to provide a breathing experience that is second to none.

Second Stage Omega 3

  • Unique all metal levered servo valve automatically maintains minimal inhalation effort throughout the entire dive
  • Patented Dynamic Adjustment automatically maintains inhalation effort throughout the dive
  • Simple twist dive/pre-dive adjustment
  • Inline ball swivel reduces jaw fatigue
  • Orthodontic mouthpiece
  • Paired with the FDX-i first stage

First Stage FDX-i

The FDX-i in-line design provides an improved flow rate, greatly reduced weight and more ergonomic port positioning for better hose routing when compared to the classic right angle first stages.

  • Precision Cold Forged
  • Reduced weight
  • The Pneumatically Balanced - consistent performance at any depth
  • Environmentally Sealed diaphragm - cold water ready
  • 4 Low Pressure and 2 High Pressure Ports
  • Angled ports for ideal hose routing
  • Improved flow rate over standard right angle first stages.

improvement on old model
Review by fred F'tang (Posted on 2/3/15)
my only criticism is that there is only one proprietary length hose, which is too short to use with twin cylinders. please make an longer hoses or an adapter for a standard hose , Oceanic !!!
Review by Bigfish (Posted on 5/13/14)
Yesterday I had the opportunity to do a few dives on the Oceanic Omega3 and it preformed as well as I expected. I have been diving the Omega’s for many years and they get better with every revision. I used my Omega1 for the Alternate Air Source and was able to compare the 2 on the dive. The Omega 3 has a much smoother air delivery than the older models.
The ball swivel and Dive / Pre-Dive switch are nice addition to the second stage. I never had and issues with turning my head in any direction. During the dive I did switch the switch into Pre-Dive mode and noticed a difference in the breakability but was still able to get ample air.
The FDXi first stage is very compact, and the angle of the upper low pleasure ports were spot on. The second stage hose came well over my shoulder to give me a comfortable dive.
