SCD 500 INT (Yoke) Diving Regulator with a balanced piston first stage

A balanced piston first stage for easy breathing

The first stage of the SUBEA 500 diving regulator is made of chrome-plated brass, with a balanced piston. The average pressure received by the second stage is constant in order to maintain the performance of the regulator, which also remains constant throughout the dive. The SCD 500 regulator is fitted with a pivoting turret to hold the hoses in the right direction around the head. There are two high-pressure (HP - 7/16”) outlets and four medium-pressure (LP - 3/8”) outlets.

Second stage and easy breathing

The second stage of the regulator has to translate natural breathing behaviour into mechanical reality. A high quality second stage significantly reduces stress and helps improve diver safety by providing air more easily and in sufficient quantity, without the need for unnecessary effort. Breathing is easier thanks to the hydrodynamic openings in the cover. The exclusive design of the cover prevents continuous flow through the regulator.

Breathing out: more visibility and less noise

When breathing out, ergonomic whiskers channel the flow of air bubbles to the cheeks so that the noise does not disturb the diver and so that the bubbles do not pass in front of the mask. Less disturbance and greater pleasure when diving!

SUBEA regulators: exclusive patented anatomical mouthpiece!

The exclusive shape of this mouthpiece, developed with orthodontists, makes it easier to keep inside your mouth thanks to the bite wings, tongue support and the different thicknesses and densities of the material (mono and dual density) that take into account the jaw closure angle. The bi-density mouthpiece of the SCD 500 regulator has a zone in contact with the gums that is more sensitive than the rest of the mouthpiece in order to limit irritation.

Regulator certification

This regulator is certified according to the standard EN 250:2014.

Tested by RINA, Genoa, Italy (certified body N°0474).

The tests are performed on a respiratory machine that simulates a diver’s breathing. The tests are performed at a pressure equivalent to a depth of 50 metres, with a ventilatory amplitude of 2.5 litres (breathing in and out), a ventilatory flow rate of 62.5 litres/minute, or 25 cycles per minute, and at a temperature of 10°C, or 4°C for cold water.

Certification and measurements of ventilatory effort

The SUBEA SCD 500 regulators are equipped with a balanced first stage and certified for use in cold water non-cold water (temperature higher than +10 °C). The DIN regulator is certified for 300 bars.

Results of the ventilatory effort certification tests (simulated pressure at a depth of 50 m in water at 8 °C) - tank pressure at 50 to 200 bars: 1.4 J/L.

The ventilatory effort is the measurement of the energy (in Joules) required for 1 litre of ventilation.

Weight and length of the hose

Weight of the first stage: 935 grams.

Weight of the second stage: 200 grams.

Weight of the hose: 150 grams.

Total weight: 1285 grams.

Hose length: 75 cm.

Maintenance advice

Never use solvents or hydrocarbon-based products to clean or lubricate the regulator yourself. Never use spray cans, because the gas propellent can attack the plastic.

Storage advice

It is important to store all diving equipment well clear of sources that produce ozone (electric motors, cookers, etc.) and to protect it against UV rays. If this is not the case, the seals can deteriorate more quickly, affecting your safety or the working order of the regulator. Keep your equipment in a dry place away from heat and direct sunlight.

Servicing the regulators

SUBEA advises you to service your regulator every two years and to make a visual inspection at least once a year. These two inspections must be made in a SUBEA certified workshop. A service is also recommended after a particularly intensive season (more than 100 dives), or after a long period of inactivity.
