About Oceanic ZEO DVT Swivel Regulator

The Pneumatically Balanced Oceanic ZEO is an Engineering Marvel of Precision, Durability and Comfort. It uses a Durable Chrome Plated Marine Brass Metal Second Stage Valve to deliver a Phenomenal Breathing Experience with Extensive Diver Control over the Air-Flow-Profile at any Depth. The ZEO comes with an In-Line Hose Swivel, Inhalation Effort Control, Dynamic Adjustment Technology Dive/Pre-Dive Switch and a Super Comfortable Orthodontic Mouth Piece. The new Cold Forged, Over-Balanced Diaphragm FDXi First Stage comes with DVT and 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, First Stage Regulator is inherently Environmentally Sealed. 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 the Contaminates to enter the Internal Mechanism.

The FDXi features DVT (Dry Valve Technology). DVT takes keeping the In ternal Components Clean of Contaminates to the Next-Level. DVT is an Innovative Design that keeps Moisture and Contaminants Out-of-the-First Stage, even if youforget to put the Dust Cap-On. Have you ever wonder why they call it a "dust cap" and not a Water Cap. DVT eliminates the possibility of Moisture entering the First Stage with a simple, yet ingenious design. No-Hassle, No-Worries. What about performance?DVT doesn't impact first stage performance even at 198' (60 meters) with just 200 psi (14 bars) in your tank. The result is an end to flooded regulators! Oceanic's exclusive DVT is designed to automatically eliminate moisture intrusion and contaminants from entering your breathing system. This means Internal Components Remain Corrosion and Bacteria Free. Amazing, Simple, Patented, and bythe way, DVT is only available on Oceanic Regulators.

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 Diving in Waters Filled-with-Contaminants or Sediment (it won't corrode). First Stage has 4 Low Pressure (LP) and 2 High Pressure (HP) Ports. The Regulators Angled Ports provide Ideal Hose Routing and Improved Flow Rate over Standard Right-Angle First Stages.

Oceanic started with the EOS, a legendary regulator known for its Comfort and Breathing Profile and ended up with the ZEO. Like its predecessor the EOS, the ZEO is also a Phenomenal Breather allowing the diver Extensive Control over the Air Flow Profile at Any-Depth. It takes this design one step further however by incorporating a Tough-and-Corrosion Resistant Chrome Plated Marine BrassValve that has better Cold Water Performance and even a Better-Breathing-Experience. The All-Metal Valve encourages the Condensation-of-Water-Vapor from your Exhalation on the Valve Housing. When you Inhale that Condensed Water Vapor Circulates with the Airflow and help to Reduce "Dry Mouth" and Increase the Overall Level of Comfort. The ZEO also comes with Oceanic's patented Dynamic Adjustment Technology, Diver Inhalation Effort Adjustment Controls, Dive/Pre-Dive Switch, In-Line Ball Swivel, 3/8" ThreadedMAXFLEX 30" (76.2cm) Hose and a Super-Comfortable Orthodontic Mouth Piece to Reduce Jaw Fatigue.

The ZEO/FDXi combination is everything you need for a sublime breathing experience at any depth and in any environment. From the balmy tropical waters of theCaribbean to the extremes of cold water diving's best dive sites, the ZEO will perform with reliability, consistency and comfort andmakes taking your favorite regulator literally anywhere, that much easier. The Regulator weighs 27.2oz (771g) without the Hose, is NITROX Compatible Up to 40% Out-of-the-Box, comes with an Owner's Manual and is covered by a 24 month limited warranty.

Questions about this item:

Shopper  The air adjustment knob does not have a hard stop when turned counter clockwise. Is this the correct functionality?
NATHAN T  Mine does the same thing and there is no performance impact.....this may be a built in clue to signal the user that they have opened all the way while the hard stop while going the other way closes the valve down to the lowest flow. This may be an Oceanic design as I own 2 of the EOS regulators and they are designed the same way Enjoy the reg... I know I do
Shopper  Good Morning, Can you tell me if this regulator is available in DIN?
