Pneumatically Balanced Valve.
The pneumatically balanced second stage on the Oceanic EOS Regulator reduces breathing resistance to
near zero with a balanced valve seat designed to respond to the
slightest inhalation.
A pneumatically balanced second stage actually has
(or can have) the same initial crack opening effort as a mechanically
balanced, but the spring force of a pneumatically balanced second stage
is lighter so it’s spring rate is also lower. Therefore the force
required to open the valve farther as flow increases is less than that
required for a mechanically balanced second stage with a higher rate
spring. So the total effort to breathe the pneumatically balanced
second stage is indeed less.
The
spring force must be just enough to overcome the difference between
downstream air pressure and upstream balance chamber pressure.
The
downstream air travels through a hole in the poppet into the balance
chamber and applies an "upstream" force just slightly less than the
downstream force.
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 adjustment
knob enables complete control... Set the inhalation requirement on the Oceanic EOS regulator to near
zero when you need ultimate performance, or tune it for greater
resistance as conditions or preferences change. Patented Dynamic Adjustment.
A common objection to adjustable second stages 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 Oceanic EOS regulator. This
mechanically balanced valve maintains your preferred breathing
resistance throughout the dive. Set it once and the EOS reg automatically
adjusts to make breathing as easy at 100 feet as it is at 30 feet -
with no additional manual adjustment.
Ergonomic A.V.S. (Adjustable Venturi System) Dive/Pre-Dive Switch.
Designed to be unobtrusive, yet easily manipulated even with the
thickest gloves, the A.V.S. deflector vane found in the Oceanic EOS regulator either
diverts airflow from the valve to the mouthpiece, producing effortless
venturi-assisted inhalation or creates enough resistance to prevent
free flow on the surface.
Stainless Steel Inline Swivel. Ever
notice that nearly every picture you see of a diver, their regulator
looks like it’s not the least bit comfortable? The Oceanic EOS regulator features an
ergonomically designed stainless steel (no plating) in-line swivel for
ultimate comfort.
Computer Optimised Design.
The Oceanic EOS regulator was 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 EOS’s unique valve, deflector vane
and housing design directs airflow from the valve directly to the
mouthpiece, producing nearly effortless venturi-assisted inhalation when diving.
Patented Orthodontic Mouthpiece with High-Density Bite Tabs.
To further reduce jaw fatigue, the Oceanic EOS regulator features a patented Orthodontic
Mouthpiece, designed to accommodate the natural overbite of the human
jaw.
Nitrox Compatible.
The Oceanic EOS FDX-10 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 Over-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 when diving. A
sealed Balanced Diaphragm design, Enviro Kit and patented DVT (Dry
Valve Technology) isolate all internal components from the environment.
2 high pressure and 4 low pressure ports allow convenient and
comfortable hose routing. The Oceanic FDX-10 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 when diving even under the most extreme conditions.
DVT (Dry Valve Technology)
Ever wonder why they call it a "dust cap" and not a water cap? Most
dust caps are not designed to keep water from entering your first
stage. Regardless of how carefully you may maintain your regulator,
water entry is a much more common problem than most divers realise.
DVT is a revolutionary regulator technology designed to automatically
eliminate moisture and contaminants from entering your first stage,
even if the dust cap is accidentally left off. DVT eliminates corrosion
of critical internal components, bacteria, hose deterioration, and
damaged gauges and computers. |
