MTX-RC 1ST STAGE
Satin-plated brass, over-moulded diaphragm first stage with heat-exchanging ribs and over-balanced design for superior cold-water and depth performance. 5 MP ports (4 rotating), 2 angled HP ports, double-swivel hose, DIN/Yoke/M26 options (DIN 300 bar, Yoke 232 bar, M26 300 bar); EN250A to 60 m; Nitrox up to 40% O2 (outside EU).
First-stage regulator with a satin-plated brass body and heat-exchanging ribs for improved thermal performance. An over-moulded endcap and environmental diaphragm reduce ice buildup and protect the first stage from impact.
- Ribbed diaphragm clamp to improve heat exchange in cold water.
- Over-balanced diaphragm design — medium pressure increases faster than ambient pressure as depth increases, improving performance at depth.
- Five medium-pressure ports (four on a rotating turret for flexible hose orientation).
- Two angled high-pressure ports for optimal hose routing and transmitter fitting.
- Double-swivel hose for increased freedom of movement and comfort.
- Easy-to-grip DIN handwheel or over-moulded yoke handwheel; releases with one hand.
- Connection options: DIN, Yoke, and M26 thread — rated DIN 300 bar, Yoke 232 bar, M26 300 bar (oxygen service).
Standards and compatibility: Tested to EN 250A for octopus use to 60 m in cold water. Nitrox/oxygen compatible up to 40% O2 outside the EU; within the EU, oxygen mixes above 21% require an M26 connection.
