Only NELEUS has a 360°revolving second stage in the world. Swing head regulator.
The "swing head" is realized by the double swivel which can revolve 360 °to the front/back and right/left. The swing of the entire secon d stage distributes the force that works to separate it from the mouth. The Bism's original design ensures the best feel of fit in your mouth all the time so your jaws and teeth will not feel tired. Ideal also for women or senior divers with smaller mouths.
Within the Bism brand, NELEUS regulator adopts titanium for its all first stage. Titanium has the high strength while its weight is about half of copper alloy, and is green material for both the human body and environment. It is proved from what is adopted for a deep sea research vessel to research the deep sea of several thousand meters of depth, F1 machine, jet engine and the space development such as the rocket. Sometimes, a regulator is exposed under the hard environment. NELEUS regulator is the model having a beautiful form made out of titanium and is equipped with the latest technology of Bism. It is the product gained the top of safety and high-grade sense that divers look for.
Lighter and yet Smoother Inhalation Feeling
Spiral Flow EX
Spiral flow is a mechanism to flow air from the valve. Along th e spiral inner wall of the mouthpiece, air flows in a soft spiral, maintaining the second stage pressure at an appropriate level while controlling diaphragm suction. It has realized a light and steady breathing experience with sufficient flow rate and little free flow.
Turbo Lever (Equipped to Spiral Flow EX)
It is the newly developed demand lever having the offset fulcrum.It minimizes the friction between the deman d lever and the valve casing when the second valve is open, and also enables to give big stroke, thus realizes large flow. It shows power for a diver with large vital capacity and the diving in the great depth.
Flow rate control system Flow Control Valve
FCV is a construction that can control the flow rate alone without changing the initial resistance.Initial resistance does not vary because it does not depend on a spring etc. It is an innovative design that both meet "flow rate" and "breathing" requirements. It assures your comfortable diving experience, allowing you to control the flow rate according to your lung capacity, breathing pattern and diving depth as you wish.
Tuned for underwater photography Exhaust tee
Exhaust tee designed to cause bubbles to flow to the rear of the diver's chin! Bubbles won't disturb you in front of the mask when you look into a underwater video or still camera viewfinder, enabling a stress-free check of the composition or focus.
One of the lightest low water temperature model (4℃)
The design is upgraded for low water temperature (4℃) while maintaining the reliability and traditional form! It has realized improved performance in essential functions while keeping the ultra-compact shape (Φ40mm× 60mm) to promise you more comfortable diving experience. A superb item that should be loved by those who know true quality goods.
Balanced twin piston system
In addition to the main piston, a sub piston (high pressure rod ) is provided to maintain the medium pressure in the first stage at a constant level.This mechanism maintains the medium pressure at a constant level unaffected by the residual pressure in the tank. The steady
"PLP" is stamped on the point for the medium pressure hose setting on the main regulator: the point stamped with "PLP" (standing for Primary Low Pressure) is the p ort for the flow rate best for breathing.
RESINA LINE SERIES
Soft, light and handy to use.
Compliance with the Food Sanitation Law attests to safety and security.
Color & design variations available (dolphin, black, white and yellow).
PLATINA NELEUS（Limited production of 100 sets）
Both the first and second stages are made of titanium, highly resistant to corrosion and scratch.
The titanium spiral flow design (use of titanium parts inside the second stage) realizes light weight and protection against rust.
The valve cone in the second stage is made of POM resin which is lighter and never rusts.
The swing head enables the supreme feel of hold in the mouth to be always sustained.
The Spiral flow EX component realizes a light and steady breathing experience.
The incorporated flow control system realizes personalized breathing aid.
