Apeks has developed unique first stages specifically for use on a twinset. The benefits of this system are that there is a minimised risk of accidental snagging, no hose kinking and easier access to the manifold valves. Each first stage has three medium pressure ports and one high pressure port. They are over-balanced, cold water compatible and extremely robust. TEK3 looks great too! Not only is the TEK3 suitable for twinset use but it is equally suitable for single cylinder or stage cylinder configurations - offering perfect, snag-free hose positioning.
First Stage
• Compact, solid one-piece body
• 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 faster rate than ambient pressure, resulting in superior performance at depth
• 1 HP port and 3 MP ports, all angled downward
• Environmental dry system keeps water out of the main spring chamber, preventing ice build-up and keeping silt and contamination out
• Maximum working pressure of 300 bar (4350 psi)
Second Stage
• Pneumatically balanced second stage for smooth, effortless breathing
• Large XTX purge buttons, easy to operate. Two-stage progressive purge: press on the side for lower flow (ideal for controlled tasks such as filling lift bags), press in the center for full purge when clearing the regulator
• Large Venturi lever with soft-touch rubber grip for easy location and use
• Lever design reduces grit ingress, minimizing friction and ensuring smooth operation
• Easy-to-grip opening effort control knob keeps the diver in control
• Second stage manufactured with active protection against infection: all molded parts include an additive effective against MRSA, E. coli, bacteria, fungi, viruses, mould, yeast, and algae
• Silicone exhaust valve improves breathing performance
• Comfo-bite™ mouthpiece virtually eliminates jaw fatigue
• Patented heat exchanger surrounding the valve mechanism dissipates cold caused by gas expansion while absorbing ambient water warmth
