A balanced piston first stage for easy breathing
The first stage of the Subea SCD 500 diving regulator is made of chrome-plated brass, with a compensated 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
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 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 INT regulator is certified up to 232 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.

Care instructions
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.

Tips for storage and maintenance
Storage tips
It is important to store diving equipment away from sources that produce ozone. Keep your equipment in a dry place away from heat and direct sunlight.
TESTS AND WARRANTY
Test product
Our technical partner: Planet Ocean (the PADI 5-star diving centre) based on the Water Sports Centre by DECATHLON in Hendaye - France. The centre uses SUBEA diving equipment throughout the year. The team of instructors are rigorously involved in the development of our SUBEA products: from the design phase with the teams (product managers, designers and engineers), to the endurance tests with the help of the centre’s divers (from beginners to trainee instructors, all year long).
Warranty
2 Years
