Description

Here some of the key features of the Apeks DS4 Nitrox 1st stage regulator:

  • Green and yellow cosmetic pieces clearly identify that this regulator is dedicated for high-percentage oxygen use.
  • The compact DS4 first stage has four medium-pressure ports and one high-pressure port (it does not feature the rotating turret found on the DST first stage).
  • Features an innovative Diver Changeable Exhaust system (DCE). This 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. Only the narrow exhaust tee is supplied with the regulator.
  • Can be converted from a right-handed hose configuration to a left-handed one. 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.
  • A braided flexi-hose comes standard. These hoses are lighter weight, more flexible and more durable.
  • Suitable for coldwater use (below 10 C / 50 F).
  • This regulator is suitable for use with up to 100% oxygen.
  • DS4 first stage.
  • 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.
  • The unique over-balanced diaphragm design has number of advantages over piston type first stages, especially when combined with Apeks Dry Sealed System, which is ideal for cold water diving or warm water diving.
  • 2 HP ports and 4 MP ports are angled for optimum hose routing.
  • An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.
  • Choose DIN or M26 fitting.
  • Popular with tech divers and twin set users due to its low profile and suitability for use with high oxygen concentrations.
