Description
First stage:
- FSR-style first stage.
- Highly polished bright chrome finish.
- Compact one-piece body.
- 4 angled medium pressure ports, 4 x 3/8″ UNF.
- 2 angled high pressure ports, 2 x 7/16″ UNF.
- Optional 5th port.
- Removable ARCAP valve seat.
- Unique over-balanced diaphragm design – as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a rate faster than ambient. This results in superior performance at depth.
- An environmentally dry system keeps water out of the main spring chamber, preventing ice build-up and keeping silt and contamination out
Second stage:
- The pneumatically balanced second stage results in smooth, easy breathing.
- The XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used – press the side of the purge for a lower flow rate, useful where more control is needed such as filling an SMB etc., then press the centre for the full effect of the purge.
- The large venturi lever has a soft rubber grip, making it easier to find and use. The lever reduces the ingress of grit and therefore resists any possible friction and gives smooth operation.
- An easy-grip control knob for the opening effort keeps the diver in control.
- This second stage is manufactured with active protection against infection, as all moulded parts are produced with an additive that kills MRSA, protects against E-coli, bacteria and fungi, and is also highly effective against viruses, mould, yeast and algae.
- A silicone exhaust valve improves the breathing performance of the regulator.
- The Comfo-bite mouthpiece virtually eliminates jaw fatigue.
- A heat exchanger (patented) surrounding the valve mechanism removes the cold caused by gas expansion while drawing in heat from the surrounding water.
The XTX40 Octopus offers the same features and performance as the XTX40 second stage and includes left/right reversibility. It comes with a high-visibility yellow front cover and a 36″ yellow hose. Suitable for cold water use (below 10 C / 50 F).
