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 Delta 3's 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.
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 Delta 3.
This mechanically balanced valve maintains a preferred breathing
resistance throughout the dive. Set it once and the Delta 3 automatically adjusts to make breathing as easy at 100 feet as it is at 30 feet - with no
additional manual adjustment.
Adjustable Venturi System (A.V.S.)
The A.V.S. deflector vane found in the Delta 3 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.
Computer optimized 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 3's unique deflector vane and housing design diverts airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation.
Lightweight
The Delta 3's housing is made from an ABS/Polycarbonate composite blend of materials making the Delta 3 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, utilizing a unique process to prevent corrosion.
Patented orthodontic mouthpiece
To further reduce jaw fatigue, the Delta 3 features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw.
Nitrox Compatibility
The Delta 3 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.
TDX-5 Titanium Balanced Diaphragm First Stage
Machined from solid Titanium alloy for light weight and corrosion resistance.
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.
PX-2 Balanced Piston First Stage
Like the name implies, the PX2 Balanced Piston is a balanced design, meaning that air flow volume is unaffected by depth or tank pressure. In other words; performance is consistent from the beginning to the end of your dive, even under difficult or deep diving conditions. The swiveled low pressure ports of the PX2 make it easy to route your low pressure hoses for your second stage, alternate air source, BC power inflator, or drysuit any way you want.
