A compensated second floor, easier breathing
The first stage of the SCD 900 diving regulator is diaphragm-compensated. Compact and lightweight, it meets all requirements.
The medium pressure received by the second stage is constant, keeping the regulator's performance constant throughout the dive.
The SCD 900 regulator has 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 rate and venturi effect
The SCD 900 regulator has two settings on the second stage.
The first is the dive/pre dive knob, to prevent continuous flow, especially when entering the water.
The second is the flow adjustment knob. When activated, it acts on the second stage's adjustment spring, allowing you to soften or harden the inspiratory effort during the dive.
The second floor and easier inspiration
The second stage of the regulator must transpose natural breathing behavior into a mechanical reality. Its high quality significantly reduces stress, helping to improve diver safety by supplying air more easily and in sufficient quantity, without the need for superfluous effort.
The hydrodynamic openings in the hood make breathing in easier. This exclusive hood design also eliminates the need for continuous flow from the regulator.
Exhalation: greater visibility and less noise
During exhalation, ergonomic whiskers channel the flow of air bubbles to the cheeks, so that the noise doesn't disturb the diver and the bubbles don't pass in front of the mask. Less discomfort during practice and more pleasure in the activity!
SUBEA regulators: exclusive anatomical mouthpiece!
The exclusive shape of this mouthpiece was developed in conjunction with orthodontists, and makes it easier to hold in the mouth thanks to its palatal fins, lingual support and different material thicknesses and densities (mono or bi-density), taking into account the angle of jaw closure.
The SCD 900 regulator mouthpiece is bi-density, meaning that the area in contact with the gums is softer than the rest of the mouthpiece to limit irritation.
Regulator certification
This regulator is certified to EN250:2014. Tests carried out by RINA, Genova- Italia (certified body no. 0474). Tests are carried out on a breathing machine that simulates the diver's breathing. Tests are carried out at the pressure equivalent to 50 meters depth, with a ventilatory amplitude of 2.5 liters (inspiration/expiration), a ventilatory flow rate of 62.5 liters/minute, i.e. 25 cycles per minute, and at a temperature of 10°C or 4°C for cold water.
Weight and hose length
First stage weight: 650 grams (DIN)
Second stage weight: 250 grams.
Hose weight: 120 grams.
Total weight: 1020 grams.
Hose length: 75 cm. Hose base: anti-bacterial Thermoplastic Polyurethane (TPU) Polyether base.
Outer cover: braided nylon for strength and flexibility. They accept more torsion than conventional rubber hoses. They avoid the sensation of the regulator pulling on the mouth.
Maintenance tips
Never use solvents or hydrocarbon-based products to clean or lubricate your regulator yourself. Never use aerosol cans, as the propellants may attack plastics.
Regulator overhaul
SUBEA recommends that you have your regulator serviced every two years, and visually inspected at least once a year. Both checks should be carried out by a certified workshop SUBEA. An overhaul is also recommended after a particularly intense season (over 100 dives) or after a long period of inactivity.
