Regulator series

The world's only 360 ° rotating second stage swing head regulator

A double swing head that can be rotated 360 degrees before and after and left and right. The power to come off from the mouth is dispersed by swinging (rotating) the whole second stage. BISM’s unique shape that always keeps the best comfort, eliminates fatigue on chin and teeth. Recommended for small women and elderly people. Compatible with either left or right installation. Octopus bassing is a regulator with excellent ease of handling and safety without stress.

Neleus commitment to titanium

Among the Beyism brands, all regulators in the Nereus series use titanium on the 1st. Titanium is perfect for seawater, so it is the best material used in seawater. Titanium is a material that is about half the weight of the copper alloy, but has a high strength, and is easy on the human body and the environment. It can be proven from the fact that it has been adopted in space development such as F1 machines, jet engines, and rockets, from deep -sea research vessels that investigate a thousand meters in water. A regulator sometimes exposed in a harsh environment. The Nereus series regulator is a model equipped with a beautiful form -shaped form and the latest BISM technology. It is a product that can be said to be the extremity of safety and luxury required by the diver.

2nd Stage

Second stage

New design second body case

Beyism’s unique new design second stage case has pursued fluid dynamics and has improved intake and exhaust performance with a deeper depth than the conventional model.

New design second body case
Vertical valve unit

It is a special structure in which valves in the second stage are arranged vertically. Since the exhalation is directly hit by the demand lever operating axis, the valve is heated by exhalation, which demonstrates a high performance in a low -water temperature environment.

Vertical valve unit
New function venture switch

Equipped with a Venturi switch. Control the venture effect properly to prevent free flow. The switch is two positions: dive ( +) and pre -dive ( -).

New design titanium face

Spiral Flow is a mechanism that controls air from the second valve. This mechanism along the inner wall of the mouthpiece, the gentle spiral air flow maintains the pressure inside the second and controls the diaphragm suction power. The spiral flow ensures the flow rate, and has a light and stable suction feeling that is difficult to free flow.

Evolved valve with a large amount of stable and stable suction
Double stream valve

By increasing the air outlet from one place to two places from the conventional place, and the air outlet is studied and exhausted, the venture effect is optimally controlled to achieve a large flow and stable air supply.
* Double Stream Valve EX is designed to supply more flow rate than the normal dollar stream valve, and is a valve that optimally controls the air flow along with the Venturi switch.

Flow Control Valve
Flow Control Valve

F.C.V is a mechanism that can control only the flow rate without changing the initial resistance. The initial resistance does not change because it does not depend on the spring. Therefore, it is a breakthrough mechanism that responds to two themes, “flow rate” and “sucking comfort” at the same time. The diver can control the flow rate arbitrarily according to the personal vital capacity, respiratory pattern, and diving depth, enabling comfortable diving.

Exploisting for underwater shooting
Exploisting for underwater shooting

Exploisty designed so that the exhaust bubbles flow behind the chin. Even when you look into underwater video or camera viewfinder, you will not feel stressed to check the composition and focus because the foam does not come in front of the mask.

Adoption of balance twisting Impiston method
Adoption of balance twisting Impiston method

In addition to the main piston, it is a BISM unique mechanism that incorporates a subpiston (high pressure rod) to keep the medium pressure value of the first stage constant. This mechanism does not affect the residual pressure in the tank and keeps the medium pressure value constant. We promise safe and comfortable diving to ensure stable breathing underwater.

(Fig. 1) The force generated by the subpiston (high -pressure rod) cancels the force applied to the high -pressure seat. Therefore, it is not affected by the remaining pressure of the tank and keeps the medium pressure value in the first stage constant. (Fig. 2) This is a mechanism with less flow rate because the air does not pass through the thin holes of the main piston.

Model compatible with low water temperature (4 ° C) of the lightest class
First stage

The first stage is made of titanium with low thermal conductivity, and the use of resin parts for the water pressure sensory department, which is more sensitive to the temperature, is highly performed in low -water temperature environments.

PLP Port

The medium pressure hose setting location of the main regulator was engraved with PLP. The PLP, which is the abbreviation of Primary LowPressure Port, is a port that secures the most suitable flow rate for breathing.
