The Apeks ATX Stage 3 Set is the predecessor of the XTX range and has been used for many years around the world. Tough and simple construction makes the ATX preferred by many divers with modern balancing and cold water performance.

Simplicity

The ATX and DS4 combination is made to be simple and to work smoothly. The ATX delivers a quiet breathe and only has one adjustment, the Venturi. The Venturi lever prevents the 2nd stage from freeflowing as readily on the surface by redirecting air inside the 2nd stage.

Prescription Lenses

Features

high-performance regulator boasts an over-balanced first stage coupled with a pneumatically balanced second stage.

The smooth, quiet breath is sure to enhance your diving enjoyment.

Suitable for coldwater use thanks to its first stage environmental dry seal and second stage heat exchanger.

Compatible with EAN40 out of the box.

First Stage

Uses the 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.
1 HP port and 4 MP ports are available.
An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.
Available in DIN and yoke.

Second Stage

Pneumatically-balanced second stage results in smooth, easy breathing.
The large purge button on the ATX is easy to operate even with thick gloves.
The integrated venturi control provides a performance boost at depth while preventing unwanted freeflow at the surface.
An extremely efficient 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.
Offers a compact, integrated exhaust tee.

Apeks ATX Stage 3 Regulator - Features

FeatureProduct Specification
Adjustable Inhalation
?This feature allows the diver to adjust the inhalation setting from the set level and increase the effort required to open the 2nd stage valve to deliver air.
No
Adjustable Venturi
?The venturi control affects how air flows in the 2nd stage. In it's positive position the flow of gas creates a vacuum against the diapragm, helping to open the valve. In it's negative position it will divert gas back against the diaphragm helping to close the valve. It is basically used to help prevent free flowing.
Yes
Cold Water Rated
?Cold water has adverse effects on regulators and can cause some to freeze so each regulator combination must be tested during manufacturing for their performance in different water temperatures.

Cold water is defined by EN250 as below 10°C. If a regulator combination cannot meet the performance standards below 10°C then they are only suitable for warm waters.


EN250 / (EN250A >10°C)
To pass the regulator must provide at least 62.5 L/min of air at 50M depth above 10°C.
Cold & Warm Water
Environmentally sealed
?Environmentally sealed 1st stages offer greater protection against freezing when diving in cold water (below 10 degrees C)

Scubapro have a new method of cold water proofing their first stages called the eXtended Thermal Insulating System or XTIS which still allows water into the first stage but the internal parts that come into contact with the water are coated to prevent ice from forming.
Yes
First Stage
?Unbalanced regulators are affected by the pressure in the cylinder, becoming slighty harder to breathe from when the pressure starts to drop.

Balanced regulators are not affected by the cylinder pressure or depth.

Over-balanced regulators achieve unprecedented performance by increasing your air supply the deeper you go providing the best breathe for deep divers.
Over-balanced
High Pressure Ports
?High pressure ports supply the pressure gauge and wireless transmitters for dive computers
1
Low Pressure Ports
?Low pressure ports supply the 2nd stages and inflator hoses
4
Service Information
?All regulators need to be serviced to keep them in working order as the parts inside them age and wear over time and with use. Most regulators need to be serviced once a year or after 100 dives with normal recreational use to replace parts and re-balance.

Some regulators use more modern materials or mechanisms that allow them to extend the servicing interval that can save you some money in the long run.
