SCD 900 INT First Stage Regulator With Compensated Membrane.

Our Subea team developed a balanced diaphragm regulator, perfect for diving in all conditions, at all depths!A compensated membrane diving regulator, comfortable and easy to breathe with, developed to dive in all water temperatures > 4°C, and under all conditions.

A balanced piston first stage for easy breathing

The SCD 900 dive regulator has a balanced diaphragm first stage. Compact and lightweight, it meets all your requirements.
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 900 regulator is equipped with 6 pre-oriented outlets to balance the position of the hoses around the head.
There are 2 high pressure outlets (HP – 7/16”) and 4 medium pressure outlets (LP – 3/8).

Adjustment of flow and venturi effect.

The SCD 900 regulator is equipped with two settings on the second stage.
The first is the dive and pre-dive dial to avoid continuous flow, especially when entering the water.
The second is the flow control dial. Activating it adjusts the spring of the second stage. It thus makes it possible to increase or decrease the breathing effort during the dive.

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 900 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.

Weight and length of the hose

Weight of the first stage: 795 grams.Weight of the second stage:250 grams.
Weight of the hose:120 grams.
Total weight:1165 grams.Hose length: 75 cm.The base of the hose is made from antimicrobial thermoplastic polyurethane (TPU) polyether.

Outer coating: braided nylon for greater strength and suppleness. Withstands more twisting than conventional rubber hoses. Prevents the feeling that the regulator is pulling on the mouth.

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.

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.
