Apeks MTX-RC First Stage Regulator

The cold water rated Apeks MTX-RC first stage features a unique over-balanced diaphragm design – as the diver descends, the overbalancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth. Over-moulded innovative endcap and environmental diaphragm, a forged 1st stage body offers maximum thermal performance.

• Suitable for cold water use (below 10°C / 50°F)
• The 5th 3/8” UNF medium pressure port includes a protective bumper when not in use.
• Forged first stage body with heat exchanging ribs for maximum thermal performance.
• Angled HP ports for optimal hose routing and fitting of transmitters.
• Forged rotating turret with medium pressure ports in a parallel direction for improved hose orientation.
• Ribbed diaphragm clamp for improved heat exchange in cold water conditions.
• Nitrox/Oxygen compatible – Up to 40% O2 outside the EU (European Union).
