The pack includes:
1 DIN Subea SCD 500 regulator with compensated piston (75 cm hose)
1 Subea SCD 500 octopus surface indicator (100 cm hose)
1 SCD Subea pressure gauge
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 2 high-pressure (HP - 7/16”) outlets and 4 medium-pressure (LP - 3/8”) outlets.
Second stage and easy breathing
A regulator second stage has to translate natural breathing behaviour into mechanical reality. A high quality second stage can significantly reduce stress and help 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 anatomical mouthpiece!
These regulator mouthpieces have been designed to be highly comfortable in the mouth thanks to their anatomical shape developed with orthodontists. The exclusive shape of this mouthpiece 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 SUBEA diving octopus is a valve second stage, with a large diaphragm and a purge button.
Its simple and robust design provides long-lasting reliability and makes the SCD octopus the ideal second stage for new
divers, as well as the perfect choice for safe diving thanks to its one-metre yellow hose for easy air sharing.
SUBEA pressure gauge: diving pressure gauge for tank pressures of up to 300 bars
300-bar pressure gauge with stainless one-piece chrome-plated brass housing, explosion-proof, shock-proof.
Copper-beryllium sensitive spiral element.
Hose with an outer diameter of 55 mm.
Male screw thread. 7/16'' HP.
Highlighting of the red zone between 50 bar and 0 bar for greater clarity and safety.
Extra ring on the side to attach the pressure gauge and keep it within reach thanks to the safety strap.
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 hoses
Weight of the first stage: 750 grams.
Weight of the second stage with hose (75 cm): 350 grams.
Weight of the octopus with hose (100 cm): 365 grams.
Weight of the pressure gauge: 260 grams.
Hose length: 75 cm.
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.
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.
