The Apeks XTX200 & XTX40 Stage 3 Regulator Set combines the flagship FSR over balanced diaphragm first stage, a pneumatically balanced XTX200 second stage and the ever reliable XTX40 Octopus.

The First stage is a balanced design and it is fitted with two high pressure, and four low pressure ports, which are placed in angles that support optimised hose routing. The redesigned first stage now offers improved gas flow, which enables it to accept a 5th low pressure port (not included in a standard).

Environmentally sealed, high performance diaphragm first stage improves performance and safety in cold water.

The pneumatically balanced second stage offers great performance. With venturi air flow control, diaphragm deflector, customisable inhalation resistance and anti-bacterial mouthpiece, the second stage is full of well-thought-out features.

Additionally, the second stage can be converted from a right-handed hose configuration to a left-handed one by our authorised service technicians before shipping, find out more here.

FEATURES:
1ST STAGE:
  • FSR style first stage.
  • Highly polished bright chrome plating.
  • Compact one-piece body.
  • 4 angled low 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 environmental dry system keeps water out of the main spring chamber thus preventing ice build-up and keeping silt and contamination out
2ND STAGE:
  • 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 purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge, i.e. when regulator clearing etc.
  • The large venturi lever has a soft touch rubber grip, which makes it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation.
  • Easy-to-grip opening effort control knob keeps the diver in control.
  • The 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 very 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) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.
  • Compatible with EAN40 out of the box.
OCTOPUS:
  • The XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used - press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge, i.e. when regulator clearing etc.
  • 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.
  • Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable.
  • Suitable for cold water use.
  • Compatible with EAN40 out of the box.
  • Pneumatically-balanced second stage results in smooth, easy breathing.
