Apeks has developed unique first stages specifically for use on a twinset. The benefits of this system are: minimized 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.
For those that already own two Apeks regulators and would like to take advantage of the Tek 3 first stages, AP0367-1, TEK 3 SET, FIRST STAGES, includes: a LH Tek 3 first stage and a RH Tek 3 first stage in one box.
This product qualifies for Free Parts for Life.
The TEK3 utilises all of the proven technology contained within the Apeks range of first stage
The ports on the TEK3 first stages are oriented so that all hoses will route downward to provide the streamlined configuration required by technical divers.
Allows unrestricted accessibility to the cylinder valves when using a twin cylinder set up.
Features an innovative Diver Changeable Exhaust system (DCE). The system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. This gives the user a choice, wider exhaust tee for minimal bubble interference (essential for underwater photography) and narrow exhaust tee for a smaller compact comfortable regulator. The regulator is supplied with both sets of exhaust tees.
The second stages can be converted from a right-handed hose configuration to a left-handed configuration. The process of changing the regulator to a left-handed configuration is both quick and simple. However this procedure must ONLY be performed by an APEKS Authorised Service Technician.
Available with DIN connection only.
Outstanding cold water performance (below 10 C / 50 F).
Compatible with EAN40 out of the box.
- 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 rate faster than ambient. This results in superior performance at depth.
- 1 HP port and 3 MP ports are all angled downward.
- An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.
- Maximum working pressure is 300 BAR (4350 psi).
