ATX 200

The ATX 200 is the new "Flagship" of the Apeks line of regulators.This feature-rich, high performance regulator, with its restyled 1st stage and smaller 2nd stage, is the perfect regulator for any diving environment. 

First Stage

• Over-balanced first stage actually increases interstage pressure as you go deeper, compensating for the denser air. 

• The high-gloss black chrome gives the first stage a sleek look. 

• The first stage comes standard with a unique "dry" environmental sealing system that completely eliminates the need for messy silicone oil or grease filling. It is designed for use in all water conditions. It is ideal for professional use and for diving in cold or contaminated conditions. 

• The unique layout of the first stage with its upswept medium pressure ports allows for ideal positioning of the hoses. 

• Can be easily changed to a DIN connection system.

Second Stage

• The new ATX 200 second stage is smaller and 25% lighter than its TX predecessor. This results in less jaw fatigue and less drag. 
• Improved exhaust gas flow reduces exhalation resistance and therefore the overall work of breathing of the regulator. 
• The ATX 200 second stage uses a pneumatically balanced valve system and is the most advanced diver adjustable breathing system available. Independent performance tests have established that this regulator can supply air within the recommended limits of breathing resistance to a depth in excess of 230 ft. 
• The ATX 200 has ergonomically designed diver adjustable controls for opening effort and venturi assistance allowing the diver to tune the breathing characteristics of the regulator to give virtually ideal breathing. No fixed or preset system can achieve an ideal level of breathing performance under all conditions. 
• The ATX 200 second stage is suitable for use in all diving conditions. Because of its high efficiency heat exchanger system, it can cope with even the coldest conditions without freezing, making it the perfect all round regulator. 
• Comes standard with the Comfo-bite mouthpiece for increased comfort.

TX 100

The TX100, while similar in performance to the new ATX 200, uses the classic Apeks 2nd stage. This regulator has become so popular, it has been left in the line unchanged

First Stage

• The first stage, with its unique design and satin finish, has a definitive blend of style, quality and high performance. 
• The first stage is dry sealed keeping all components protected from the environment. 
• Two high pressure ports and four medium pressure ports are angled for optimum hose positioning. 
• The over-balanced first stage actually increases interstage pressure as you go deeper to compensate for the denser air. 
• The first stage can easily be converted to a DIN connector

Second Stage

• Pneumatically balanced second stage makes this a superior breather. 
• An adjustment knob allows diver to select necessary opening effort. 
• The venturi and breathing resistance are fully adjustable by you, the diver, so you can tune the regulator to your personal breathing requirements. 
• A second stage heat exchanger increases regulator-freezing resistance. 
• The large sweptback exhaust tee is excellent for bubble dispersion. 
• Comes standard with the Comfo-bite mouthpiece for increased comfort

ATX 50

The ATX50 Regulator is for the discriminating diver who wants the benefits of a feature-rich regulator at a moderate price.

First Stage

• High performance regulator that boasts an over-balanced first stage with a pneumatically balanced second stage. 
• Four medium pressure ports are located on a swivel turret to reduce tension on the hoses. The primary port is enlarged for maximum flow. 
• Two high-pressure ports are available for redundancy. 
• The first stage is dry sealed keeping all internal components protected from the environment. 
• Can be easily changed to a DIN connection system.

Second Stage

• The new ATX50 second stage is smaller and 25% lighter than its TX50 predecessor. This results in less jaw fatigue and less drag. 
• Improved exhaust gas flow reduces exhalation resistance and therefore, the overall work of breathing of the regulator. 
• The ATX50 second stage uses a peneumatically balanced valve system and is the most advanced diver adjustable breathing system available. 
• The ATX50 has ergonomically designed diver adjustable controls for opening effort and venturi assistance allowing the diver to tune the breathing characteristics of the regulator to give virtually ideal breathing. No fixed or present system can achieve an ideal level of breathing performance under all conditions. 
• The ATX50 second stage is suitable for use in all diving conditions. Because of its high efficiency heat exchanger system, it can cope with even the coldest conditions without freezing, makking the perfect all round regulator. 
• Comes standard with the Comfo-bit mouthpiece for increased comfort.

DS4 / TX-50

• The first stage comes standard with a 300 bar DIN connector. 
• The first stage is dry sealed keeping all internal components protected from the environment.

Second Stage

• The TX50 second stage uses a pneumatically balanced valve system and is the most advanced diver adjustable breathing system available. 
• The TX50 has ergonomically designed diver adjustable controls for opening effort and venturi assistance allowing the diver to tune the breathing characteristics of the regulator to give virtually ideal breathing. No fixed or preset system can achieve an ideal level of breathing performance under all conditions.
