The unsurpassed performance of this first stage results from a balanced piston design which delivers significantly more gas than any other first stage design while leaving performance completely unaffected by changing tank pressure.

- Balanced, flow-through, freeze-resistant piston provides high performance
- Rotating swivel provides flexibility and super clean hose routing
- Two high pressure ports, five High Flow intermediate/low pressure ports
- 300 bar DIN, compatible with 40% Nitrox (outside EU)
