Even with the best laid dive plans, there are times you encounter conditions beyond your control. The Oceanic Delta
4 is one hot new regulator ready to take on all challengers with improved performance,
new features, improved styling, and the new FDX-10 First Stage featuring our
exclusive Dry Valve Technology (D.V.T.) Features of the Oceanic Delta 4 regulator include:
Diver adjustable
inhalation effort. Our Patented Dynamic Adjustment automatically maintains
inhalation effort throughout the dive.
Adjustable
Venturi Switch (A.V.S.) for simple Dive/Pre-Dive Adjustment
Paired with
the new FDX-10 Balanced Diaphragm regulator featuring Oceanic's exclusive D.V.T. (Dry
Valve Technology) that helps put an end to flooded regulators without sacrificing
performance! D.R.T. is a revolutionary regulator technology designed to automatically
eliminate moisture and contaminants from entering your first stage even if
the dust cap is left off eliminating corrosion of critical internal components,
bacteria, internal hose deterioration and damaged gauges and computers.
Diver Adjustable Inhalation Effort Most downstream demand valve regulators are calibrated during manufacturing to a single, 'middle of the road' operation. Whether finning up current at 100+ feet or merely snorkeling out to the dive site, this factory adjustment may not be optimum for the wide variety of demands we place on our equipment. A simple twist of the Oceanic Delta 4.1 regulator adjustment knob enables complete control...set the inhalation requirement to near zero when you need ultimate performance, or tune it for greater resistance as conditions or preferences change.
DVT (Dry Regulator Technology) 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 70m with just 150 bar in your tank.
The result? An end to flooded regulators! Oceanic's exclusive DVT is designed to automatically eliminate moisture intrusion and contaminants from entering your breathing system.
Amazing. Simple. Patented. And by the way, only available on Oceanic Regulators.
Patented Dynamic Adjustment A common objection to adjustable second stage regulators is that divers can't imagine themselves twisting and turning a knob as they descend and ascend through the depths. If inhalation resistance is set near zero at depth, your ascent would require you to manually increase resistance as ambient water pressure is reduced to prevent free-flow. Taking another stride beyond common second stage engineering, Oceanic designed a patented DYNAMIC ADJUSTMENT feature into the heart of the Delta 4 Regulator. This mechanically balanced valve maintains a preferred breathing resistance throughout the dive. Set it once and the Oceanic Delta 4.1 Regulator automatically adjusts to make breathing as easy at 30m as it is at 10m - with no additional manual adjustment.
Adjustable Venturi System (A.V.S.) The A.V.S. deflector vane found in the Delta 4.1 diverts the airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation. With the addition of a user Adjustable Venturi System (A.V.S.), in the form of a simple yet ingenious switch, full adjustment control rests in the hands of the diver.
Improved Adjustment Mechanisms Both the Dynamic Adjustment Knob and A.V.S. Switch are designed to be unobtrusive, yet easily manipulated even with the thickest gloves.
Surge Deflector Our surge protector (the titanium, blue or yellow that you see in the images above) reduces freeflow caused by surge or oncoming current.
Computer optimised design Oceanic regulators are exclusively designed using the latest 3-D computer modeling techniques. This allows us the ability to model and test performance while still in the early stages of development. The Delta 4.1 regulator unique deflector vane and housing design diverts airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation.
Lightweight The Delta 4.1 housing is made from an ABS/Polycarbonate composite blend of materials making the Oceanic Delta 4.1 regulator both extremely rugged and lightweight (6.7 ounces) and nearly neutrally buoyant underwater, reducing jaw fatigue on extended dives. The extremely ligweight cover ring is machined from a solid piece of aircraft aluminum, and then hard anodized, utilising a unique process to prevent corrosion.
Patented Orthodontic mouthpiece with high-density bite tabs To further reduce jaw fatigue, the Oceanic Delta 4.1 regulator features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw.
Nitrox Compatibility The Oceanic Delta 4.1 regulator is classified as being suitable for use with nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts.
FDX-10 Balanced Diaphragm First Stage Forged from marine-grade brass, the Oceanic FDX-10 1st stage regulator features optimised air paths and angled hose ports for superior performance and comfort. A sealed Balanced Diaphragm design, Enviro Kit and patented DRT TM (Dry Regulator Technology) isolate all internal components from the environment. 2 high pressure and 4 low pressure ports allow convenient and comfortable hose routing.
WORK
OF BREATHING
Did you know that it costs energy to breathe? The amount of energy your
regulator requires to move each liter of air is called work of breathing
(WOB). Lower work of breathing equals lower effort required to breathe
and increased comfort and safety during a dive.
How
to Read Work of Breathing Charts The computer-generated breathing machine chart presented above
represents a regulator's performance per standards established by the
U.S. Navy's Experimental Diving Unit. Tests are conducted at 198 feet
with approximately 3000-psi supply pressure, 25 breaths per minute of
2.5 liters each.
(1)
Inhalation - The chart shows one complete breath cycle, starting
with inhalation on the left and continuing along the bottom to the right,
staying mostly below 0.0; thus the inhalation work of breathing is reported
in negative numbers.
(2)
Exhalation - The exhalation effort begins on the right and
runs across the top to the left. These are all positive numbers since
a diver (or the machine in this case) is blowing out (exhaling) rather
than inhaling.
(3)
WOB - The total area inside the loop formed by the two lines
is what the computer analyzes to calculate the regulator's total work
of breathing - the amount of energy the regulator requires to move each
liter of air.

The FDX10
is a great first stage. I really like the way the ports are angled, so that
the hoses are much more streamlined. The Dry Valve Technology is also a bonus,
I never have to worry about the dust cover not being on properly ever again.
The Delta 4 is my favorite second stage regulator. The 30 degree inline swivel
ensures it sits comfortably through an entire dive, putting an end to ‘jaw fatigue”.
The fact that it is user adjustable is also fantastic, I can go from pool diving
with my Scuba Rangers, to a deep wall dive, to shallow diving around the local
piers and my reg will always perform just the way I like it. Combined with the
FDX10 first stage this would be the best breathing regulator that I have dived
on.

The FDX 10 Delta4
is an exceptional regulator. Its superior flow rate makes it perfect for all
types of diving. Whether I''m 60m down inside a wreck, battling a strong current
or chasing a wayward student the Delta4 is an easy-breathing, reliable regulator
that always performs above my expectations.
As a PADI MSDT and TDI Instructor, I spend a great deal of
time teaching Open Water, Advanced, Specialty and even Technical dive courses
and therefore I need reliable, comfortable and easy to use equipment.One of the most important pieces of dive
equipment is of course the regulator.As
I dive a great deal I find invariably I need a regulator set up that allows me
hassle free diving with easy flow of air from my tank and a first stage that is
robust, reliable and accommodates my every whim.
The Oceanic Delta 4 first stage has become a must for me as
a dive professional.It is a robust
first stage that I can rely upon in all dive conditions and through a variety
of dive requirements, from Nitrox diving, deep diving and dive teaching.The Oceanic Delta 4 has never failed me in
any dive condition and is an essential piece of dive equipment that I carry
with me for all dives whether I’m teaching or simply enjoying a casual dive.
In the vast range of dive equipment available to divers and
dive professionals it is rare to find a first stage that accommodates all my
needs and so I stay with my Oceanic Delta 4 first stage as it stays with
me. I would recommend the Oceanic Delta
4 Fist Stage to any diver – recreational or professional – for all standards
and experiences.
